Track rollers are self-retaining, single or double row units with particularly thick-walled outer rings.
These bearings can support axial forces in both directions as well as high radial forces.
The bearing outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where there is misalignment in relation to the raceway and edge stresses must be avoided.
The track rollers are available with an inner ring, with a stud and with a plastic tyre on the outer ring.
