Sealmaster RPBXT housings are mounted pillow block units: the cast iron housing seats an insert bearing and is fastened to the structure through its base, so the shaft rotates supported and aligned. They are used in equipment where the load is radial and the mounting must sit firmly on a bedplate or frame. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, and advises you on choosing the right variant.

The RPBXT designation is read in parts: the letters identify the pillow block housing family with insert bearing, and the number following the prefix indicates the shaft size for which the unit is intended. The final suffix, such as the 4 in RPBXT-204-4 or RPBXT-208-4, distinguishes the construction variant within that size. That is why two references with the same number can differ in their configuration: send the full code, for example RPBXT-211-4 or RPBXT-300-4, so we can point you to the equivalent option.

In Argentine industry these housings appear in belt conveyors, bucket elevators, mixers, mills, screens and continuous process lines. They are also found in water treatment equipment, food plants and agro-industrial facilities, where the drive shaft needs robust support that is easy to replace. Being mounted units, they simplify assembly and maintenance of the assembly compared with a loose bearing with a separate housing.

To select correctly, take into account the shaft diameter and length, the expected radial and axial load, and the type of shaft attachment the unit accepts. Check the sealing according to the environment: dust, moisture or frequent washdown require additional protection. During mounting, rest the base on a flat, rigid surface, align the housing with the rest of the line and tighten the bolts evenly. Lubrication and insert bearing clearance are controlled according to the duty cycle.

As for equivalences, mounted housings are compared between manufacturers by shaft size, housing type and attachment system, not by the commercial code. A unit from another brand can cover the same function if those characteristics match, even if tolerances or sealing differ. If you need to replace an RPBXT reference, send us the code and the shaft dimensions: we will point you to the compatible alternative and quote it.
