Sealmaster 2-7/16"-ID 4-BOLT TRB PILLOW BLOCK SEA RPB-207-4
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.

Browning® offers an extensive multi groove sheave offering. This includes Browning® SPLIT TAPER® and QD® bushing designs. This means maximum economy and versatility for your application. Truly the right drive every time! Our exclusive B5V® sheaves have a patented design that offers 5 V hp in the economy of a B section sheave. B5V® sheaves serve 90% of all applications from 10 to 150 hp. This can reduce cost up to 40% over traditional designs.
Browning® torque limiters are torque control devices that slip under excessive load but automatically carry the desired load after the excess has been removed. The device can be easily adjusted to slip at a desired overload and automatically re-engage when overload is removed. Overload should be removed promptly since prolonged slippage can be detrimental to the friction disc. Generally, no resetting is required after the torque limiter has slipped. Torque limiters help prevent machine and product damage and costly downtime caused by shock loads, overloads or machine jams but should not be used as clutches.
