Tapered Roller Bearings
Sealmaster® RPB-CR series contains heavy duty tapered roller bearings for radial, thrust and combination loading

Fluoropolymer Coated Cast Iron Split Housings
This non-stick coating on the housing and cap bolts, offers resistance to chemicals. In our testing, it performs better than painted or nickel coated housings. Stainless steel cap bolt washers and grease fittings also provide resistance to corrosion. Permanent metal nameplate allows for easy identification.

Replaceable Cartridge Insert (RCI)
The heart of the RPB-CR is the unitized, self-aligning cartridge insert with integral seals and double locking collars. The replaceable cartridge insert can accommodate +/- 3° static misalignment capability has factory controlled clearances and is factory sealed and lubricated. The cartridges fit all housing styles and are field replaceable for quick change out. RCI outer races are black oxide treated.

Contact Seals
Single lip race mounted contact seal is composed of a steel inner seal with a bonded elastomeric sealing member. The steel inner seal is press fit into the inside diameter of the outer race. The bonded elastomeric sealing member is held in the proper rubbing contact position on the outer diameter of the inner race. Black oxide seal stampings inhibits corrosion.

Positive Lubrication System
Positive lubrication system provides direct grease path to the bearing. The unit is designed with two lubrication ports in the cartridge OD. This is so that one of the lube holes in the cartridge lines up with the grease fitting, regardless of insert orientation in the housing. A rubber grommet in housing top recess directs lubricant into bearing cavity. Extra lubrication ports help prevent seal damage by venting excess pressure from over greasing. Sealmaster alignment pin helps prevent outer race rotation.

Collar Mount System
Two fluoropolymer coated locking collars are standard on all units. These consist of two setscrews at 120° for balanced three point contact. Precision manufactured diamond faceted setscrew design contributes to improved clamping and resistance to back out. Single locking collars are available where space limitations are present.

Specialized Food Grade Lubrication
The Sealmaster RPB-CR bearings are factory-filled with Sealmaster GoldPlex-FG (Food Grade) grease (USDA H1 approved). This makes them suitable for mounted bearing lubrication where incidental contact with food products may occur. They may be used in any application where clean, routine lubrication is required.
