The Rex Rexnord mounted spherical roller bearing is a unit ready to mount on drive shafts. It combines a spherical roller bearing with its housing, which simplifies installation and alignment in equipment where the shaft is not perfectly parallel. It is used in conveyors, mixers, mills and process machinery. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, and helps you identify the correct size for your application.

The Rex designation identifies Rexnord's family of mounted spherical roller bearings. Within the series, each reference combines the housing type, the shaft diameter and the locking system. That is why, to request a quote for a Rex, it is best to indicate the shaft size and, if you have it, the complete part number. With that data, the exact variant is determined: split or one-piece housing, locking by setscrew, eccentric or adapter, and the corresponding sealing.

These mounted bearings are chosen in industries such as food, cement, mining and material handling. In Argentina they appear in belt conveyors, bucket elevators, mixers, mills and continuous process equipment. Their self-aligning capability absorbs slight misalignments and shaft deflection, which is common in welded structures or structures subject to vibration. They also simplify maintenance because the unit is replaced without machining the shaft.

To select a Rex properly, take into account the radial and axial load, the rotation speed and the environment. In areas with dust or water, sealing is decisive: choose the variant with labyrinth or oil seal depending on the degree of exposure. Mounting requires cleaning the shaft, verifying that the tolerance and fit are correct, and lubricating before closing. Initial alignment and periodic lubrication with the right grease extend the life of the unit.

As for equivalents, mounted spherical roller bearings are interchangeable between manufacturers if the shaft diameter, the housing type and the mounting dimensions match. It is not enough for the series to be similar: the center height, the distance between holes and the locking system must be compared. If in doubt, send a photo of the nameplate or of the old unit and we will verify it with you.
