Sealmaster 1-3/4"-ID 4-BOLT BB FLANGE UNITS SEA SF-28
Sealmaster® gold mounted ball bearings feature a wide outer race insert bearing with land riding metallic retainer. The black oxide treated bearing steel insert features an exclusive lock pin and dimple system providing a direct path for lubrication into the bearing and prevents outer ring rotation within the housing. Shaft lock is achieved by either setscrew or Skwezloc® concentric locking collar. The felt seal with flinger provide a good balance between contaminant entry, GoldPlex® HP grease loss and friction.
