A pillow block housing from the SEALMASTER RPBA line holds a rotating shaft in place on industrial machinery. It suits arrangements where the load travels mostly along the radius and the base has to stay firm so alignment does not drift. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams across the United States and Latin America, alongside bearings, mounted units, seals and power transmission components.

Reading the code is the first step. RPBA is followed by a three-digit figure that points to the shaft size, then a suffix that tells you which sealing arrangement is used. RPBA-103-2 and RPBA-104-2 are two consecutive sizes, and the -2 ending marks one particular seal configuration. Because the digits alone do not give you the full picture, match the complete code against the manufacturer's dimension table, or send it to us and we will confirm what it covers.

You will find these units on conveyors, belts, elevators, mixers, mills and other process equipment in food, chemical, cement and material handling operations. Feed plants, aggregate processing sites and packaging lines rely on them where the housing has to stand up to dirt and moisture. Typical applications include feed plants, aggregate processing sites and packaging lines, where the housing has to stand up to dirt and moisture.

Choosing the correct housing comes down to four inputs: shaft diameter, whether the load is radial, axial or combined, the environment around the unit, and how it will be fastened. The RPBA series mounts through base bolts, so alignment and torque values deserve attention during installation. Lubrication and seal selection should reflect what the housing is exposed to, whether that is dust, water or chemical contact.

SEALMASTER housings can be swapped with units from other makers that work to equivalent standards, including SKF, FAG or NTN, provided the critical dimensions and the fastening style line up. Codes are not shared between manufacturers, so have a specialist validate the match before you commit to a replacement.
