Why is Angular Soft Foot so destructive?

Why is Angular Soft Foot so destructive?

Tightening a motor foot that has Angular Soft Foot forces the

foot to make contact with the base, creating unwanted

stresses on the motor housing through the motor’s leg.

These stresses can distort the motor housing and twist

bearings, bending the shaft and causing shaft wobble.

Angular Soft Foot will cause:

Angular Soft Foot will cause:

Ultimately, the result will be premature

bearing failure and shorter motor life.

• extra strain on the bearings and seals

• eccentricity of the motor air gap, reducing

efficiency and increasing heat

• excess strain and wear on couplings

How can you recognize Angular Soft Foot?

How can you recognize Angular Soft Foot?

Inconsistent flat rise readings during alignment indicate

Angular Soft Foot. Check the gap under each corner of the

foot with feeler gage. If the measurements are not the same,

the motor may have an Angular Soft Foot condition.

Have you ever “Chased Your Tail”?

How does Sof’ Shoe shim work?

How does Sof’ Shoe shim work?

• It’s made of a specially formulated elastomer

• Cold flows and sets to fill any irregular gaps

between foot and base

• Creates total surface contact

• It is an “instant” step shim

What makes Sof’ Shoe shims so effective?

What makes Sof’ Shoe shims so effective?

• Unique properties retain about 50% of it’s flexibility

allowing it to conform to any shape

• Takes a permanent set after ten to fourteen days

under standard bolt torque compression

• Enables instant motor startup after alignment

• Stable to 225 degrees Fahrenheit
