The SEALMASTER RFBA-CR is a 4-bolt flange housing that comes as a mounted bearing unit, ready to bolt onto a flat surface. The insert bearing turns on the outer race, which makes installation and replacement straightforward. It is commonly used on conveying, mixing and process equipment that needs a secure, compact mounting. MR Industrial Accessories supplies this series in metric sizes from 45 to 80 mm.

The RFBA code identifies the 4-bolt flange housing family. The number that follows is the shaft diameter in millimeters: RFBA 45MM-C CR fits a 45 mm shaft, while RFBA 80MM-C CR fits an 80 mm shaft. The -C suffix denotes the construction variant within the series, and CR means the unit has a contact seal at the sealing area. Reading the code correctly helps you order the right replacement without confusion.

These housings are found in belt conveyors, bucket elevators, mixers, screens and packaging lines, as well as in water treatment and food processing equipment where the flange makes cleaning and disassembly easier. Because it is a mounted unit, the whole assembly is replaced at once, which cuts downtime compared with assembling a bearing in the workshop.

When selecting a housing, confirm the shaft diameter and the bolt hole spacing on the flange. The RFBA-CR series handles moderate radial and axial loads; if the equipment runs with misalignment, consider a self-aligning housing instead. During mounting, tighten the four bolts in a cross pattern with even torque to avoid distorting the flange. Follow the lubrication schedule for the duty cycle and inspect the CR seal if you notice leaks or dust entry.

Flange housings from different brands use their own part numbers. Interchangeability depends on flange dimensions, shaft diameter and mounting type, not just the code. For a quote, send the complete part number and, when possible, the flange and shaft dimensions. We can then point you to a compatible option from the lines we supply.
