The SEALMASTER RFB is a four-bolt flange housing that mounts a bearing to a flat surface, holding the shaft in place. The flange provides support and keeps the bearing aligned, spreading the load across the four bolt points. It is a good fit when you need a rigid, front-mounting unit that is easy to install and remove.

The RFB code works like this: the letters indicate the four-bolt flange design, and the number that follows is the shaft size in millimeters. So RFB-35MM, RFB-40MM, and RFB-50MM cover shafts from 35 to 50 mm, and RFB-60MM and RFB-70MM handle larger sizes. The MM suffix confirms metric dimensions. When you send the full part number, we can quote the exact housing you need.

These housings are common on conveyors, belts, elevators, mixers, blowers, and process lines where the bearing bolts to a panel or frame. Plants handling food, chemicals, or aggregates choose them for the simple front mounting and because the shaft can be removed without tearing down the machine. They also show up in bottling, milling, and material handling, even in dusty, wet, or washdown conditions.

To pick the right one, start with the shaft diameter from the part number, then check the bolt hole spacing and flange diameter against your drawing. Match the seal to the environment—clean areas need different protection than wet or dirty ones. During installation, set the flange on a flat, clean surface, tighten the four bolts in a cross pattern, and verify shaft alignment before final torque. Keep up with lubrication and recheck the bolts periodically to extend service life.

SEALMASTER is a Regal Rexnord line of mounted bearings, and its flange housings are often cross-referenced with similar products from other brands. Interchangeability is not just about shaft size: you must also compare housing type, hole count and position, sealing, and shaft locking method. If you have a part number from another brand, send it with the flange dimensions and we will identify the compatible option in the RFB series.

If you already know the part number, send it by WhatsApp along with a photo or sketch of the flange and its main dimensions. We will quote the corresponding SEALMASTER housing and suggest other variants if needed. We also supply bearings, power transmission components, seals, and lubricants, so you can cover everything in one inquiry.
