RPBA housings from SEALMASTER are mounted units that pair an insert bearing with a pillow block body, so the assembly can be bolted directly onto the machine frame. They suit rotating shafts that need firm support and a straightforward installation. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams in the United States and Latin America, and assists with unit selection based on shaft size and how the housing will be mounted.

Reading an RPBA part number is simple once you know the pattern. The letters point to the pillow block housing family; the figure after them gives the shaft diameter in millimeters; the trailing digit tells you the mounting style or hole count. So RPBA-35MM-2 is a two-hole housing built for a 35 mm shaft, and RPBA-60MM-4 is a four-hole version for a 60 mm shaft. With that logic you can decode any reference in the series and order the exact unit.

Typical installations include conveyors, belt systems, elevators, mixers, mills and other process machinery in food, chemical, cement and material handling operations. Feed plants, aggregate processing sites and packaging lines rely on these units because they mount easily and hold up under constant duty. A housing that fits properly keeps the line running and reduces unplanned downtime.

Selection comes down to a few points: shaft diameter, the radial and axial loads involved, and where the unit will operate. Review the sealing arrangement as well, since SEALMASTER units generally use lip seals that keep lubricant in and contaminants out. During installation, line the housing up with the shaft, secure it to a flat base and tighten the bolts evenly. Lubricating on schedule and checking internal clearance helps the bearing reach a long service life.

Mounted pillow block housings from other manufacturers can serve as replacements when the critical dimensions line up: shaft diameter, hole spacing, height to center and mounting style. Compare those figures against the drawing or the part you are removing before committing. If you need an alternative, our team can point you to a compatible option for your application.
