They can roll directly on the tray under heavy load and shock load. They are greased for life. Under normal operating conditions, they are maintenance-free, while they should be re-lubricated under severe working condition to prolong the working lifespan.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.
