Sealmaster® 703271 NP Series Standard-Duty Pillow Block Ball Bearing Unit, 2-7/16 in Dia Bore, 6-7/8 to 7-5/8 in L Bolt Center-to-Center, 2-3/4 in Base to Bore Centerline, 9-1/2 in OAL x 5-9/16 in OAH
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. Depending on your preference, these bearings are available in both inch and metric shaft sizes with a wide variety of cast iron, stamped steel or rubber mount housings, sealing, and lubrication options or industry specific solutions.
