Sealmaster® 700748 ST Series Non-Expansion Standard Duty Take-Up Ball Bearing Unit, 1-15/16 in Dia Bore, 5-7/8 in L x 2-3/16 in W x 4-5/8 in H, 7889 lb Dynamic Load
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.
