Ball bearing track rollers are self-retaining, single or double-row ball bearings with particularly thick-walled outer rings. In addition to high radial forces, these bearings can also support axial forces in both directions.

Yoke-type track rollers are single or double-row units mounted on shafts or studs. They comprise thick-walled outer rings with a profiled outside surface and needle roller and cage assemblies or full-complement rolling element sets.
