Support rollers (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 needle roller or cylindrical roller sets. Yoke type track rollers can support high radial loads as well as axial loads arising from slight misalignment and skewed running.

Support rollers (yoke-type track rollers) 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 based on needle or cylindrical roller bearings. They are available in several designs and variants:

• with or without a cage
• with or without axial guidance (flange rings)
• with or without an inner ring
• with or without seals (sealed or open)
• with crowned or cylindrical (flat) outer running surface profile
