Roller bearing track rollers (yoke and stud type roller bearing track rollers) are mounted on shafts or studs (yoke type track rollers) or supplied with a heavy-section roller stud with fixing thread and a mounting aid (stud type track rollers). They comprise thick-walled outer rings with a profiled outside surface and needle roller and cage assemblies or full complement needle roller or cylindrical roller sets. They can support high radial loads as well as axial loads arising from slight misalignment and skewed running. They are not mounted in a housing bore, but are supported on a flat mating track. They can be adjusted to the mating track in the design with the eccentric collar, thus permitting, for example, larger manufacturing tolerances in the adjacent construction.

They are designed to run on all types of tracks and to be used in cam drives, bed ways, conveyor systems, linear guidance systems, etc..

They are available in two designs as below:

• Support rollers (yoke type roller bearing track rollers)
• Cam followers (stud type roller bearing track rollers)
