SEALMASTER RPB series pillow blocks are mounted bearing pillow block units, designed to support rotating shafts in equipment where a solid base and stable alignment are required. They are used in conveyors, fans, mixers and process machinery. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, and advises you on choosing the right size according to shaft diameter and load type.

The RPB designation is read in parts: the letters identify the mounted bearing pillow block family, and the numbers that follow indicate the shaft diameter in millimeters. For example, RPB-35MM-2 corresponds to a 35 mm shaft, RPB-50MM-2 to a 50 mm shaft and RPB-65MM-2 to a 65 mm shaft. The final suffix distinguishes construction variants within the same size: RPB-60MM-2 and RPB-60MM-4 share the 60 mm diameter but differ in configuration. Send the complete part number to identify the exact variant.

These pillow blocks are used in the food, cement, chemical and aggregate processing industries, among others. In Argentina it is common to see them in belt conveyors, bucket elevators, horizontal mixers, centrifugal fans and packaging lines. The pillow block base allows them to be bolted to steel or concrete structures, and the built-in bearing supports radial loads and some axial thrust depending on the mounting. For dusty or humid environments, seal selection is key.

When choosing an RPB pillow block, check the shaft diameter, load type and environmental conditions. The seal must be compatible with dust, water or cleaning agents. Proper lubrication and correct internal clearance extend service life. During mounting, ensure a flat, clean surface, align the pillow block with the shaft and tighten the mounting bolts evenly to prevent deformation. If the equipment runs with vibration, periodically check bolt tightness and seal condition.

Regarding equivalents, SEALMASTER RPB pillow blocks can be interchanged with units from other brands that share the same shaft diameter and base configuration, such as the SY, FY or UCP series from recognized manufacturers. Interchangeability depends on mounting dimensions, center height and shaft fastening type. Matching the diameter is not enough: hole spacing and load capacity must be compared. If you need to replace an existing pillow block, send us the part number or dimensions and we will point out the compatible alternative.
