ROLLER BEARINGSRoller bearing consists usually of 2 rings inner
and outer. Between them are placed bearing rollers. Bidirectional
axial bearing has an additional middle ring and its rolling bodies
are placed in 2 rows.
ROLLER BEARINGSTypes of roller bearingsDivision according to
direction of loading:a) Radial.b) Axial.
ROLLER BEARINGSTypes of roller-contact bearingsDivision
according to contact shape of rollers with rings:a) Bearings with
point contact.a) Bearings with line contact.
ROLLER BEARINGSTYPES OF ROLLER BEARINGSAccording to the shape of
inner rollers:a) Ball bearings.b) Roller bearings.c) Needle
bearings.d) Cone bearings.e) Spherical roller bearing.
ROLLER BEARINGSTYPES OF ROLLER BEARINGSAccording to number of
rollers rows:a) Single in-line bearings.b) Dual in-line
bearings.The shape of radial bearings rings can be adjusted to
higher axial loading. Such bearings are called bearings with
tapered contacts. Tapered bearings are used to equalize hub axis
and shafts position.
