The SEALMASTER RFB flange housing is a mounted bearing with a four-bolt housing, designed to fasten the shaft to a flat face of a machine or structure. The flange centers and supports the assembly, so that the bearing runs aligned and the load is distributed over the four anchoring points. It is used where a compact, rigid, front-mounting unit is required, with the shaft passing through or supported on the flange.

The RFB series designation is read from the number that follows the letters: that value indicates the shaft diameter in millimeters, as in RFB-35MM, RFB-40MM or RFB-50MM. The RFB abbreviation identifies the four-bolt flange family, and the MM suffix confirms that the size is expressed in millimeters. By that logic, RFB-60MM and RFB-70MM correspond to larger shafts within the same series. By sending the complete part number, MR Accesorios Industriales will quote the unit you need.

These housings appear in conveyors, belts, elevators, mixers, blowers and process lines where the bearing is bolted to a sheet metal panel or a frame. In food, chemical and aggregate processing plants they are chosen for the ease of front mounting and for the possibility of removing the shaft without disassembling half the machine. They are also seen in bottling, milling and material handling equipment, in environments with dust, moisture or frequent washdowns.

To select correctly, start from the shaft diameter shown in the part number and verify the bolt hole spacing and the flange diameter against the machine drawing. Check the sealing type according to the environment: a clean area is not the same as one with water or particles. During mounting, seat the flange on a flat, clean surface, tighten the four bolts in a cross pattern and check shaft alignment before applying the final torque. Proper lubrication and periodic retightening of the anchors extend the life of the assembly.

SEALMASTER is a Regal Rexnord line of mounted bearings, and its flange housings are commonly cross-referenced with other equivalent families from different brands. Interchangeability is not defined by shaft diameter alone: you must compare the housing type, the number and position of the holes, the sealing and the shaft locking system. If you have another brand's part number, send it along with the flange dimensions and we will point you to the compatible alternative within the RFB series.

If you already know the part number, send it by WhatsApp to MR Accesorios Industriales along with a photo or sketch of the flange and the main dimensions. With that we will quote the corresponding SEALMASTER housing and, if you need another variant of the series, we will tell you how to proceed. We also carry bearings, power transmission, seals and lubricants to complete the order in a single inquiry.
