RPB SEALMASTER housings are pillow block mounted bearings: a unit that combines the bearing with its housing, ready to be fixed onto a base and support a rotating shaft. They are used when a simple support is needed, with two anchoring holes, and a bearing that comes already aligned and protected inside its housing. MR Accesorios Industriales sells them in Buenos Aires, Argentina, for power transmission equipment in plants and workshops.

The RPB series designation is read in parts: the letters identify the pillow block housing family and the number that follows indicates the shaft size for which the unit is built. The final suffix distinguishes sealing and configuration variants within the same series. That is why RPB codes share a format but change in size; to choose correctly you must read the full code, not just the base number.

These housings appear in conveyors, belts, elevators, mixers, pumps, fans and process lines. In Argentina they are found in food, cement, chemical, meatpacking plants and metalworking workshops, where the environment has dust, humidity or frequent washdowns. The pillow block unit simplifies mounting on sheet metal or profile structures and allows replacing the assembly without redoing the anchoring.

To select, start from the shaft diameter and the type of load: predominantly radial or with axial thrust. Review the sealing according to the environment, because it defines protection against dust and water. During mounting, rest the housing on a flat, rigid base, align the shaft with the driven equipment and tighten the anchoring bolts evenly. Lubricate according to the duty cycle and check clearance and temperature at startup.

Among brands, mounted housings are interchanged by shaft number, base configuration and type of sealing, not by each manufacturer's commercial code. Two references from different brands can cover the same function if shaft dimensions, hole spacing and center height match. The compatible alternative is sought with that data and the equipment load.

If you have the code of the housing you are replacing, send it via WhatsApp to MR Accesorios Industriales along with the shaft diameter or a photo of the assembly. With that we will quote you the SEALMASTER reference and tell you how to mount it. We can also evaluate sealing variants within the same RPB series for your application.
