DESCRIPTION
The Sealmaster® RPB mounted tapered roller bearings are a dimensionally interchangeable upgrade from competitive type E bearings. The exclusive features include unitized replaceable inserts, self-aligning capability and split housing. They also include the Sealmaster® alignment pin. This provides a direct path for lubrication into the bearing and helps to prevent outer race rotation. The Sealmaster® RPB is available with two traditional setscrew locking collars for easy installation. The felt seal with flinger provide a good balance between contaminant entry, grease retention and friction. Depending on application requirements, these bearings are available in both inch and metric. They provide a wide variety of housing, sealing and lubrication options.
