SEALMASTER RPB series pillow blocks are mounted bearing units built to carry rotating shafts where a firm base and steady alignment matter. Conveyors, fans, mixers and process equipment are typical homes for them. MR Industrial Accessories supplies this line to customers throughout the United States and in several Latin American countries, and can guide you toward the right size based on shaft diameter and the type of load involved.

Reading the RPB code is straightforward. The letters stand for the pillow block family with a mounted bearing, the digits that follow give the shaft diameter in millimeters, and the closing suffix separates construction variants of one size. So RPB-35MM-2 fits a 35 mm shaft, RPB-50MM-2 a 50 mm shaft and RPB-65MM-2 a 65 mm shaft, while RPB-60MM-2 and RPB-60MM-4 cover the same 60 mm diameter in two different configurations. Quote the full part number when you write to us so the exact variant is identified.

You will find these housings in food processing, cement, chemical and aggregate operations, and in belt conveyors, bucket elevators, horizontal mixers, centrifugal fans and packaging lines. Bolting the base to a steel or concrete structure keeps the unit in place, and the bearing inside handles radial loads plus a degree of axial thrust depending on how it is mounted. Where dust or moisture is present, the sealing choice becomes the deciding factor.

Selection comes down to three checks: shaft diameter, load type and the environment the unit works in. The seal has to suit dust, water or the cleaning agents used nearby. Lubrication and correct internal clearance both affect how long the housing serves. At mounting, work on a flat, clean surface, line the housing up with the shaft and tighten the base bolts evenly so the housing is not distorted. On equipment that vibrates, inspect bolt tightness and seal condition at regular intervals.

For replacements, SEALMASTER RPB housings can be interchanged with units from other manufacturers that share the same shaft diameter and base layout, including SY, FY or UCP series. What decides compatibility is mounting dimensions, center height and the shaft locking method. A matching diameter by itself tells you little, since hole spacing and load capacity also have to line up. Send the part number or the dimensions of the housing you are replacing and we will point you to a compatible option.
