SRF55SS Track Runner Bearings, Sealed, 2.750" Outside Diameter, 1.5000" Inner Diameter

This RBC caged roller follower can operate directly on a hardened and ground shaft (HRc 58 min, 16 rms min surface finish) or can be used with matching inner rings. Operating without an inner ring yields the largest possible shaft diameter with greatest strength and rigidity. Axial guidance must be provided by the application. It is recommended to use hardened steel or bronze thrust washers with radial lubricating grooves as needed. This caged SRF roller follower is popular in applications requiring oil bath lubrication, high speed, or in applications greased for life. RBC Bearings has been providing bearing solutions to our customers since 1919. A publicly-traded company (NASDAQ: ROLL), RBC currently has 23 manufacturing facilities worldwide, with 18 located in the USA.

• Designed with large internal grease storage capacity for applications where relubrication is infrequent
• Cage guided rollers permit operation at high speeds
• Double sealed to keep contaminants out on one side, but allow for free lubrication flow on the other side
• Considerably heavier cross section outer ring to reduce deformation under load
• Yoke style design allows for clevis mounting which provides support on both sides of the cam follower and permits use of a high strength pin
