Support rollers (yoke-type track rollers) with axial guidance (flange rings) and an inner ring
Support rollers (yoke-type track rollers) are designed to run on and to be used in cam drives, bed ways, conveyor systems, linear guidance systems, etc. They have a thick-walled outer ring with a profiled outer running surface and are supplied ready-to-mount. They can support high radial loads as well as axial loads arising from slight misalignment and skewed running. The inner ring contains a lubrication hole to facilitate relubrication.

They are available in several designs and variants:
• with crowned or cylindrical outer running surface
• with cage or without cage (full complement needle roller)
• gap seal on both sides or three-stage sealing by plastic axial plain washers
• high carbon chrome steel or stainless steel
