SEALMASTER RPB-CR pillow blocks are mounted bearing assemblies built to carry rotating shafts on industrial machinery. The housing is rigid and the sealing arrangement is designed for areas where dust, moisture or splashing liquid is present. Typical installations include conveyors, fans, mixers and process equipment. MR Industrial Accessories supplies this line and helps customers work out which configuration fits their equipment.

Reading the code helps you order the right unit. RPB is the pillow block family within the SEALMASTER line. The digits that come next, as in RPB 103-C2 CR or RPB 112-C2 CR, tell you the shaft size the block is made for. C2 marks the sealing or locking variant, and the CR ending points to a particular coating or treatment. Put together, the full number describes a complete assembly that arrives with the bearing already seated in the housing.

On the plant floor these blocks show up on belt conveyors, bucket elevators, mixers, centrifugal fans and packaging lines. Aggregate processing equipment uses them as well, and food plants often specify them because the perimeter seal helps keep contamination out. Because the mounting base is flat, they bolt onto flat beds or profile frames, which simplifies alignment and makes changeouts during maintenance less of a job.

Selection comes down to three things: shaft diameter, the nature of the load (radial, axial or a combination) and where the unit has to work. The CR seal gives extra protection where dust and water are present, so inspect the lip for damage before you install it. Use the lubricant the manufacturer calls for and refresh it according to the duty cycle. Line the block up with the shaft and draw the mounting bolts down evenly so you do not introduce parasitic stresses.

Units in this series can be swapped with other brands as long as shaft dimensions and hole spacing line up. When you ask for a quote, it pays to compare center height, shaft diameter and mounting style. If the equipment you are working on carries a different designation, MR Industrial Accessories can point you to a compatible option within the SEALMASTER line or among the other brands the company carries.
