Yoke type track rollers are single or double row units fitted on studs. They comprise thick-walled outer rings with a profiled outside surface and needle roller and cage assemblies or full complement sets of cylindrical or needle rollers. 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 bearings are available with or without an inner ring as well as in open and sealed versions.
