McGill 4-1/4"-ID NEEDLE ROLLER BEARINGS MCG MR-68
McGill® CAGEROL® machined race needle bearings are manufactured from bearing quality steel. Most sizes use crowned or end relieved, rollers to help reduce end stresses and allows for greater misalignment. The rollers are separated by a steel retainer (cage) to help achieve higher speeds and provide a lubricant reservoir. CAGEROL® bearings are constructed with radial lubrication hole and groove on the outer and optional inner raceway (MI series) for relubrication through the housing or shaft. Other options include a variety of seal configurations to either help prevent contaminant entry or contain the lubricant.

Sealmaster® 701241 FB Series Non-Expansion Round Straight Standard-Duty Flange Mount Ball Bearing Unit, 1-1/4 in Dia Bore, 2-3/4 in L Bolt Center-to-Center, 3-Bolt Flange Mount, 1-7/8 in OAL/Dia
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.
