The Rexnord PT Select is a mounted spherical roller bearing: the unit combines a self-aligning bearing with a housing that already has the mounting holes, so it bolts directly to the structure and stays aligned without any machining. It is used where the shaft is not perfectly aligned with the machine or where there is flexing in the frame, because the spherical element accommodates misalignment. MR Accesorios Industriales sells it in Buenos Aires, Argentina.

The PT Select series is identified by its trade name and is ordered by size: when requesting a quote, it is best to indicate the shaft diameter and the type of housing the machine needs. As it is a series, there is no single part number: each size has its own reference. If you have the code stamped on the old part, send it as is; if not, the shaft diameter and a photo of the housing are enough to locate the variant. At MR Accesorios Industriales they reply promptly with the corresponding alternative.

These mounted bearings appear in belt and chain conveyors, bucket elevators, mixers, mills, screens and process equipment. In food, cement, grain and aggregate processing plants they are common because they tolerate dust, moisture and impact loads. They are also found in medium-sized fans and pumps, where the flanged or pillow block housing simplifies anchoring. In the Argentine market they are in high demand for replacement of imported equipment and for machines that work outdoors.

To choose well, first look at the housing type: pillow block, flanged, take-up or wall mount, depending on how it anchors to the structure. Then check the sealing: in environments with fine dust or washdown, a more closed protection is advisable than in a clean room. Lubrication is with medium-consistency grease and must be replenished according to operating hours and temperature. When mounting, rest the housing on a flat surface, tighten the bolts in a cross pattern and verify that the shaft turns freely before coupling the transmission.

Regarding interchangeability, mounted bearing series from different brands replace each other when the shaft diameter, housing type and shaft locking system match, whether with set screws, taper bushing or adapter. It is not advisable to rely only on the code: those three things must be compared. If the original housing has a different height or hole, sometimes a new flange or base can be adapted. Send the code or size via WhatsApp to MR Accesorios Industriales and they will help you find the equivalent.

Before ordering, have on hand the shaft diameter, the housing type and, if possible, a photo of the installed part. With that data the PT Select series variant is identified and last-minute changes are avoided. Write to us on WhatsApp with the code or model you need and we will quote you promptly.
