Support Rollers With Flange Rings With An Inner Ring

Contact Now

Support Rollers without flange rings are designed for applications where associated components limit axial movement of the outer ring. Based on needle roller bearings, these support rollers are available with or without an inner ring. Support rollers with an inner ring have an inner ring that is slightly wider than the outer ring to avoid axial clamping of the outer ring. Support rollers without an inner ring are intended for arrangements where the pin or shaft is hardened and ground.

Support rollers (yoke-type track rollers) are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc.. They are based on needle or cylindrical roller bearings. SKF supplies them ready-to-mount. They are available in several designs and variants:
