SKF Cooper split bearing types

Expansion (EX)

The inner race is clamped to the shaft, and moves axially with it when expansion or contraction occurs. The SKF Cooper expansion bearing offers virtually no resistance to axial movement as the rollers spiral through the outer race.

Fixed (GR)

Provides axial location to the rotating elements of machinery. Can sustain axial and radial loads.


Used where the axial movement is greater than is possible with the EX type due to the use of long shafts or high temperature variation. Axial expansion takes place between the lengthened inner race and the rollers, maintaining the load central to the cartridge to help preserve bearing alignment


Intended for the fixed bearing position where there is both radial axial loading and the GR type is unsuitable. Two rows of opposed rollers to take axial loading in either direction.
