Nothing Outlasts a Diamond.

DIAMOND CHAIN HISTORY

Arthur C. Newby, Edward C. Fletcher and Glenn Howe, with a $5,000 investment, started

what was to become the Diamond®Chain Company by forming The Indianapolis Chain &

Stamping Company on December 24, 1890. They took the diamond as their

trademark because it symbolized perfection and acted as a constant

reminder of their endeavor.

In its humble beginnings, The Indianapolis Chain &

Stamping Company (IC&SC) specialized in bicycle chain. As

one of the first companies in the United States to produce

bicycle chain, IC&SC prospered, outgrowing its original quar-

ters and moving to larger facilities in 1892.

In 1901, when the bicycle chain business slumped, IC&SC

rebounded by developing and introducing to industry a twin-

roller roller chain.

From December 17, 1903, when Diamond chain was used on

the Wright brothers’ first flying machine, to the present, Diamond Chain has been

a major supplier of chain not just for aircraft, but for power transmission and product convey-

ing throughout manufacturing industries.

In 1950 Diamond Chain was acquired by American Steel Foundries, Inc. – the largest steel

foundry in the world, and in 1962 the name of the parent company was changed to AMSTED

Industries Incorporated.

During Diamond’s many years of producing the highest quality roller chain they have tested,

examined and discovered many developments which have significantly increased the perfor-

mance of their roller chains. These developments have rarely become “product lines” but

rather, “product improvements” which have been incorporated into daily

production so that all customers can benefit, without special requests

or premium prices.

In addition to continued product improvement, Diamond

has introduced a detailed roller chain Drive Selection

Software program. This software will improve the way chain

is specified by engineers and designers by simplifying a

multitude of sometimes difficult calculations and equations.

In today’s environment, Diamond, while focusing on

the increased use of technology, still operates under the same

3

inventive, grassroots philosophy it was founded on – providing its customers

customers with a high-quality product possessing the best balance

with high-quality product processing the best of performance, reliability

price and delivery that meet or exceed their requirements.

If you’re looking for the best roller

chain for the job, it’ll pay to take acloser

look at Diamond roller chain. Diamond roller chain may look

like your everyday chain, but upon closer inspection the unique

differences that make Diamond chain better become evident.

From the strict attention to detail we devote to every chain

design, to the extra steps we take during fabrication and assem-

bly operations, those differences really add up. We build long

life, lasting value and enduring customer relationships into every

link of chain...that is the Diamond difference.

Over the years we’ve produced tens of thousands of types of roller chain

for a wide variety of applications from oil field and deco ovens,

to conveyors and combines. So, if your application calls for some

special attention, our application engineers can easily help you

find that lasting solution.

Please, take a closer look at Diamond roller chain...we do.

That closer look is what makes ours better than other chains.

And what you can’t see, you can experience with improved

performance – which means less downtime, less repair costs,

and increased productivity. Those are just

some of the differences that a Diamond chain makes.

ISO 9001

Building high-quality roller chain is a matter of demanding

precision – a matter of establishing critical parameters, both in

component fabrication and final assembly, and monitoring them

to ensure that they are maintained.

ISO 9001 certification is awarded to companies that develop,

and consistently adhere to, a well-documented quality system. ISO 9001 requires compliance

with 20 elements, some of which include customer

service, contract review, manufacturing procedures, and product design and

development. Diamond is ISO 9001 certified. That means you can be sure that Diamond chain

is consistently manufactured following detailed processes developed by Diamond and proven to

produce some of the longest running and best performing roller chain.

Each component of a Diamond chain is engineered and produced with optimum perfor-

mance in mind. Exacting specifications cover critical properties of all component parts and

assemblies. Diamond’s ISO 9001 certification is proof of the fact that “we say what we do and do

what we say.”

API

We produce our Oil Field chains with the same attention to detail that goes into all our products.

but additionally these models are subjected to performance testing in accordance with API

(American Petroleum Institute) Specification 7F. Only those companies which have established

quality systems, approved and routinely audited, are authorized to display this symbol.

CHAIN COMPONENTS

Roller chain is not that hard to understand. It is normally made up of five components:

Collectively, these components produce a series of “traveling bearings.” To accomplish this, the chain

is assembled with alternate inside and outside links. The inside links that employ bush-

ings and/or rollers are called roller links, and the outside links that employ the pins are

called pin links, or connecting links. In operation, the pins articulate inside the bush-

ings leaving the rollers free to turn on the outside of the bushings for

“rolling” action as the chain enters and exits the sprocket.

Every Diamond chain is made from the highest quality raw

materials available. Starting with the proper raw materials is the

foundation of any quality product. Diamond pays close attention

to chemistry and dimensional specifications which are critical fac-

tors as the material is transformed into components capable of

handling the toughest job. Producing these components requires

painstaking attention to detail and control of fabrication, heat treat-

ment, finishing and assembly processes. Other chain manufacturers

may do a good job in some of these areas but at Diamond, we consis-

tently do it better in all.

MANUFACTURING PROCESS

Diamond jewels are sought out because of their

enduring perfection. The same argument can be made

for a Diamond chain. But, unlike precious gems,

Diamond chain is readily available directly from us or

your authorized Diamond distributor.

The process of manufacturing the longest lasting chain

begins by purchasing the materials to our detailed specifications.

We do this because we must specify chemistry, dimensional size and

even the direction of the grain in order to fabricate components capable of performing to

your expectations.

Transforming these raw materials into individual components that meet our high stan-

dards is no easy task. Again, we’ve learned that attention to detail is a key to achieving the

desired result, which is the user’s

satisfaction. Some of the steps taken to provide this satisfaction are:

Link plate pitch holes are produced using a three-part process to

create a polished hole with maximum bearing area and minimal surface

imperfection. Maximum bearing area increases chain integrity, and a

smooth surface within the pitch hole maximizes the ability to han-

dle heavy loads,

especially in fatigue-sensitive applications. Even with the three-

part process,

link plates are left with a small “breakout” area. To minimize the

effects of this, Diamond provides a unique identifying feature on

our 19.10mm through 57.20mm pitch, standard and heavy series

ANSI chains. This identifying feature, a beveled edge, is unique to

Diamond, and we use it to orient and assemble the link plates in a direc-

tion which minimizes negative effects of the breakout.

Many years ago, Diamond discovered that forming bushings and rollers from strip pro-

duced a far superior component, particularly when the chain operated in an application that

subjected it to bushing/roller fatigue. Diamond also developed processes which orient the

chain bushings to position the seam away from the load bearing

surface. Positioning the bushings results in a smoother, more uniform bearing surface and

helps to reduce chain length variation. In 6.40mm through 31.80mm pitch ANSI chains, our

standard

bushings and rollers are produced using this method. This is

because in these sizes horsepower is

most often transmitted at higher speeds with relatively low

loads.

Beginning with 38.10mm pitch, Diamond provides

solid rollers because in the majority of

applications horsepower is transmitted using higher loads

and lower speeds. Under these conditions the integrity of a

solid roller is beneficial and therefore, it is provided. There are, of

course, exceptions to these standards and depending upon the specific

conditions, solid rollers are available either by design or customer request.

To most users, the obvious indication of quality is superior wear life. Poor wear life often

leads to regular adjustment or replacement, which reduces productivity and adds cost to an

operation. Heat treatment of component parts is an additional procedure to prolong wear

life which gives them the ability to perform to their optimum, depending upon what the

environment may be. In the vast majority of applications, wear life is critical, so Diamond

heat treats those components which control chain elongation very carefully.

Virtually all of our standard pins, bushings and rollers are carburized, or case hardened.

This closely controlled process transforms the outside of the parts into a hard, wear-resistant

surface

but allows the inner core to remain tough and ductile so as to absorb

normal shock loading.

In most applications this combination provides the perfect bal-

ance between wear resistance and durability.

Link plates, on the other hand, are not normally subject-

ed to wear but must be tough to resist

the loads, sometimes heavy, to which the chain may be

exposed. Their heat treatment is designed

to produce tough, ductile and shock-resistant properties, but

sometimes heat treatment is not enough. For those sizes that are rou-

tinely subjected to heavy or shock loads Diamond further conditions

the link plates using a process called “shot peening.” In this process, small steel pellets, or

shot, are propelled at the link plates. When they strike the surface they leave

a tiny indentation which causes the material to work harden. This work hardening creates

compressive stresses on the surface of

the link plate that allows it to resist, beyond conventional heat

treatment, premature fatigue failures.

The attention to detail that goes into the fabrication of component parts is not forgotten

when assembly operations begin. During the assembly of every pitch of Diamond chain, four key

components (pin, bushing, pin link plates and roller link plates) are examined carefully. These

four parts are critical in maintaining chain integrity and controlling chain length. Sections of

chain are tensile-tested for conformance to Diamond’s specifications which are greater than

those specified by ANSI, The American National Standards Institute. Sub-assemblies are evaluat-

ed, too, for both pin and bushing press-out force. Holding-power tests are done to ensure that

the sub-assemblies are of the highest quality and will not become the “weak link” in the chain. All

this “self inspection” allows us to examine how the parts work separately as well as together.

And, when new components are added during assembly, additional tests are

performed to ensure the integrity of the complete chain remains unchanged.

Diamond even identifies our chains with a unique code, we call it a “date stamp,” that is

applied during assembly. This code gives us information about the components used to produce

the chain. This means that Diamond Chain has traceability as to the material used to produce

a component, fabricated on a specific piece of machinery, heat treated in a specific furnace and

finally, assembled on a specific date. That’s a significant feature that other chain manufacturers

just don’t have.

One might think that assembly is the final step in producing a product, but at Diamond we

still have a couple of things left to do. After the chains are assembled, we apply an initial load to

the chains, called preload. This loading approximates the recommended loading a chain can

expect in service. Preloading is done to align the various chain components such as pins, bush-

ings and link plates. Preloading helps eliminate initial elongation and can increase the usable

service life of your chain.

We even subject our own product to performance testing at conditions well beyond recom-

mended limits. Tests on link plate fatigue, roller/bushing fatigue and initial lubrication wear are

performed to search out the chain’s endurance limits. This “torture testing” allows us to set rec-

Extra roller/bushing capacity of Diamondchain is a result of formed bushings androllers which have more perfect roundnessand grain structure orientation.

Extra link plate capacity of Diamondchain is a result ofdetail to pitch holepreparation and of shot peening external surfaces.

HEAVY SERIES CHAINChain Descriptions and Dimensions

Heavy Series ChainHeavy Series chains, also built in accordance with ANSI B29.1, are designed using link plate material from the next larger size chain. Heavy Series chains are not necessarily stronger than Standard Series chains, but the thicker link platematerial provides an increase in fatigue resistance for those drives subjected to heavy shock loads, multiple stops/starts or revers-ing.

HIGH STRENGTH/LIFT CHAINChain Descriptions and Dimensions

Produced in accordance with ANSI B29.1, these chains are designed for the rigors of heavy loads and lifting. Depending on yourspecific application, Diamond offers three options from which to choose.

High Strength (HS) Drive ChainsHS Series Drive chains are built in accordance with ANSI B29.1 and are dimensionally identical to Heavy Series Drive chains, butare specially designed and incorporate pins produced from medium carbon alloy steel. These pins are through-hardened to givethe chain a higher working load capacity and additional resistance to fatigue in high load and pulsating type applications. Users ofthese chains should remember that wear life may be slightly reduced due to the material and heat treatment of the chain pins.Slip-fit type connecting links and offset links are not available for these chains.

Note: Offset links and slip-fit connecting links are not recommended for any High Strength or Lift Chain.

Hoist ChainThese chains are built in accordance with ANSI B29.24 and are dimensionally identical to Standard Series Drive chains, but alsoincorporate pins produced from medium carbon alloy steel, through-hardened, to give the chains higher working load capacity andadditional resistance to fatigue. Additionally, these chains are produced with solid rollers for increased performance when loadingis high, but speeds are slow. Users of these chains should be aware that wear life may be slightly reduced due to the material andheat treatment of the chain pins.

SPECIAL LUBRICATED CHAINChain Descriptions and Dimensions

RING LEADER®O-ring ChainDiamond’s RINGLEADERO-ring chain is specifically designed for applications that don’t permit regular lubrica-tion, requiring thechain to depend entirely upon initial factory lubrication throughout its service life. Depending upon the specific conditions, RINGLEADERcan provide up to ten times the wear life of standard chain.

Industries such as agriculture, food processing, packaging, printing, textile and chemical processing can introduce contaminants that damage standard chain. Dirt, mud, food particles, paper fines, dust and moisture can cause buildupon the chain and clog the openings on standard roller chain where lubrication enters the pin/bushing area. These contaminantscan even get inside the chain, actually damaging the surface of pins and bushings.

RINGLEADER O-ring chain is constructed with O-rings that seal a specially formulated lubricant into every joint. This sealed-inlubricant is essential for the chain’s optimum wear life and the O-rings also help to seal out and protect the internal surfaces from dirt, contaminants and moisture. Diamond recommends that RING LEADER O-ring chainreceive periodic external lubrication to maintain moisture on the external O-ring surfaces and to lubricate roller/sprocket contact surfaces. Note: Standard RINGLEADER O-ring chain can routinely operate in ambient tempera-tures up to 66° C. For higher temperature requirements, special O-rings can be substituted, allowing operation in temperatures of206° C or greater.

■ O-rings keep lubrication in and contaminants out.

■ Special bushings, having very uniform wall thickness, are precisely heat-treated to obtain an optimum balance of strength, wear resistance and toughness. The bushings are extended beyond the roller link plates. This feature helps theO-ring stay in position and provides maximum pin support, resulting in greater bearing area for the pin.

■ Pins are made from a special alloy steel and are hardened and centerless ground. Rigid quality standards ensure precise hardness control for high wear resistance and toughness.

15


Because the RING LEADER chain lasts up to ten times longer than regular chain, overall economy of operation is improved. Withlubrication already sealed into the chain, maintenance expense is lowered. RINGLEADER O-ring chain experiences less wearelongation during normal operation, thus providing a longer service life. Life cycle costs of RINGLEADERchain can be dramati-cally less than for standard chain in certain applications which translates into longer lasting roller chain and a real cost savings.

When the environment or location of your roller chain drive is such that regular lubrication is not possible or practical, considerDiamond Chain’s Special Lubricated chains. Diamond offers two types of Single- and Double-Pitch Drive or Conveyor chainsdesigned specifically to deliver the highest level of performance– even in applications that can’t, or don’t receive proper lubrica-tion.

DURALUBE®ChainFor applications where regular lubrication is a challenge, DURALUBE can offer a longer lasting solution. This chain is constructed using a one-piece powdered metal bushing/roller combination which has lubricant drawn in under vacuum. In ser-vice, this lubricant is released and provides supplemental lubrication to the pin/bushing joint between regularly scheduled mainte-nance.

CORROSION/MOISTURE RESISTANT CHAINChain Descriptions and Dimensions

Nickel-Plated ChainDiamond Chain produces a full line of Nickel-Plated roller chains for a variety of uses in environments where the chains areexposed to moisture. Common uses include applications exposed to the weather, high humidity or those on machines that are fre-quently washed down with water.

Diamond Nickel-Plated chain is different from many rust-resistant chains, because Diamond electroless nickel plates all of thecomponents before assembly, virtually eliminating the possibility of stress-corrosion cracking. Pre-assembly plating also ensures all components are plated, which prevents internal rust from seeping out and causing contami-nation.

Note: These chains are not intended to resist corrosion from caustic chemicals or acids. For those types of applications, stainless steel chain is recommended.

CORROSION/MOISTURE RESISTANT CHAINChain Descriptions and Dimensions

Stainless Steel Chain

Diamond produces a wide range of Single-Pitch Drive and Double-Pitch Conveyor chains manufactured in four combinations ofstainless steel depending upon the specific application.

AP Stainless Chain:This chain is assembled using 300 Series (austenitic stainless) link plates, bushings and rollers along with a precipitation-hardened stainless steel pin. This combination increases the wear life of this chain over those constructed entirely of 300 Series components. AP Stainless chains are well suited for food processing, and are approved by the Food and Drug Administration. AP Stainless will be supplied unless otherwise specified.

300 Series Stainless Chain:These chains are assembled entirely from 300 Series (austenitic) components. Theyhave excellent corrosion resistance and very low magnetic permeability but cannot be expected to have the same wear resistanceof our heat treated stainless chains. For industries that require it, 300 Series chains can be considered “non-sparking.”

400 Series Stainless Chain:These chains are manufactured using 300 Series link plates but have pins, bushings and rollers that are produced from 400 Series (martensitic) heat treated stainless. This combination significantly increases wear resistance over those that are constructed using only 300 Series stainless chains. The properties of the 400 Series heat treated parts may, in some instances, cause them to discolor when in contact with certain chemicals.

600 Series Stainless Chain:These chains are assembled using 300 Series link plates, with pins, bushings androllers made from 600 Series (17-4/17-7) precipitation-hardened stainless.

Attachment Hole SizesDiamond’s attachment hole sizes are sometimes unique. Diamond has such a long history of producing roller chain that many ofour attachments were designed long before any standardization was adopted throughout the industry. We continue to produce our most common attachments with holes to accommodate the following screw sizes:

If your application requires a different attachment hole than shown in this section, please contact Diamond as many alternate lugholes are available. Many can be shipped from stock.

ATTACHMENT CHAIN CONSIDERATIONSChain Descriptions and Dimensions

Assembly:While it is possible to purchase base chain or attachment components and construct an attachment chain, it isstrongly recommended that chains be ordered and assembled at the factory to ensure the proper fit and alignment of all partsalong with any length or matching requirements.

Manufacturing Length Tolerance:ANSI defines the permissible length of an assembled section of roller chain. The allowable length tolerances vary from model to model and are also affected by the chain’s construction, i.e., with or without attachments.

As an example, the assembled length tolerance for an ANSI one inch pitch chain (#80) is + 1.33mm/-.000mm per meter. When attachments are added to the chain’s design, the tolerance for length expands to + 2.66mm/-.000mm per meter. This means that a section of #80 chain 12 pitches long (304.8mm nominal) can measure as long as305.206mm but no less than 304.8mm. The same section of chain assembled with bent, straight, or extended pin attachmentscould measure as long as 305.6mm but again, no less than 304.8mm.

In common practice, manufacturers strive to produce chain nearer to the nominal figure, but the maximum allowable length toler-ance should always be considered when designing for take-ups and catenary chain sag. If the application requires it, some designand assembly steps can be taken to direct the length of the chain toward the nominal. However, on a routine basis machinedesigns based on a nominal or specified chain length should be avoided.

Length Matching of Roller Chains:Many applications require two or more chains, normally with attachments, torun in parallel with “flights” joining the chains together forming a conveyor or transfer type system. In these cases it is critical tohave the chains ordered as a set, matched for length and installed on the machinery with the same relationship to one another aswhen they were manufactured.

Diamond offers two degrees of matching for parallel operation:Class I and Class II

Class I -A Class I match assures that the longest and the shortest chain in a given set will not vary in overall length by morethan .500mm/m. Again using #80 chain as an example, the length of two #80 chains 120 pitches long will not vary by more than1.524mm in overall length (3.048m x .500mm/m = 1.524mm). The shortest could measure 3048mm + .000mm (remember, no negative tolerance) and the longest could measure up to 3048mm + 1.524mmand satisfy the Class I requirement. Class I matching is most often accomplished by assembling the chains from selected lots ofcomponent parts.

Class II -A Class II match is much more stringent and assures that the longest and the shortest chain in a given set will notvary in overall length by more than .167mm/m. Applying this new tolerance to the above example, the length of two #80 chains 120 pitches long will not vary by more than .508mm in overall length (3.048m x .167mm/m =.508mm). The shortest could measure 3048mm + .000mm and the longest could measure 3048mm + .508mm and satisfy therequirement. Class II matching is quite difficult and requires some very unique procedures.

Differences -It is important to remember that matched chains still fall under the overall length limitations imposed by eitherANSI or the manufacturer. Matching does notassure the user of chains with a finite overall length, only that the chains in theset have a controlled relationship to one another.
