Sealmaster® gold mounted ball bearings feature wide outer race insert bearing with a land riding metallic retainer. The black oxide treated bearing steel insert features an exclusive lock pin and dimple system. This provides a direct path for lubrication into the bearing. It also helps prevent outer ring rotation. Available with 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.
