Track roller bearings are essentially cylindrical roller or needle roller bearings which have a thick-walled outer race.

Yoke type track rollers can support high radial loads and axial loads arising from misalignments and skewed running and are suitable for cam drives, slideways, conveying equipment etc.

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 bearings are available with or without an inner ring as well as in open and sealed versions.
