Sealmaster 1-7/8"-ID 4-BOLT BB FLANGE UNITS SEA SF-30
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.

MasterDrive H13/16 H Series Double Split Tapered Bushing, 3/16 in Dia Bore, 1-5/8 in Dia Barrel, 2-1/2 in Dia Flange, 1-11/32 in OAL, Powdered Metal
Double Split Tapered Bushings are used on sheaves, sprockets and pulleys to provide increased clamping force over standard bore-to-size components. They are tapered in design with flanges and utilize cap screws to tighten on the shaft. The double split design assures better concentricity to the shaft and provides the highest degree of mechanical locking component to component. Most sizes are contructed of ductile iron to provide strength and duarability. Each Split Taper Bushing series is produced in a number of different bore size options, most that include a keyway, allowing users flexibility when using sheaves, sprockets or pulleys in applications that may utilize various shaft sizes.
