RA-RR, RA-RRB NON-RELUBRICATABLE TYPES

These bearings are an extended inner-ring type with a self-locking collar. Due to the positive contact, the land-riding R-seal provides improved protection against harmful contaminants and retains lubricant under severe operating conditions. RA-RR series are factory-prelubricated and have cylindrical outside diameters. RA-RRB series have spherical outside diameters for use in housings with corresponding spherical inside surfaces to provide unrestricted initial alignment. suggested shaft tolerances:
