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.
Browning® mounted ball bearings feature multiple housing styles, materials and configurations, an extended inner race insert bearing with ball riding nylon retainer. The insert features a rivet to prevent outer ring rotation and is available with setscrew, eccentric or BOA concentric locking collar. The contact seal with black oxide treated flinger provides a good balance between contaminant resistance, grease loss and friction.
