For mounting a bearing flat against a wall, frame or gearbox face, the SEALMASTER RFBA series offers a four-bolt flange unit that takes up little axial room while holding the shaft securely. MR Industrial Accessories LLC supplies this line and helps you match the unit to your shaft diameter and load conditions.

The RFBA code breaks down simply: the letters indicate the four-bolt flange family, and the number that follows gives the shaft size in millimeters. So RFBA-45MM, RFBA-50MM, and RFBA-60MM fit shafts of 45 mm, 50 mm, and 60 mm respectively, with the series moving in 5 mm increments up to its largest sizes. The MM suffix confirms metric sizing, which matters when you are working alongside inch-based equipment.

These units are at home in belt conveyors, packaging lines, mixers, blowers, and process equipment where the bearing mounts to a vertical or horizontal structure. You will also see them in milling machinery, food plants, and workshop builds that call for a self-aligning, easily replaceable unit. The four-bolt pattern spreads the load more effectively than a two-bolt design.

When selecting a unit, consider shaft diameter, the type of load (radial, axial, or combined), and the operating environment. In dusty or damp areas, pay attention to the bearing's sealing; where slight misalignment is present, the unit's self-aligning feature helps compensate. During installation, set the flange on a clean, flat surface, tighten the bolts in a cross pattern, and verify shaft alignment before startup.

Interchange between brands is based on shaft diameter and hole spacing, not on the commercial code. For a replacement, provide the complete code along with the flange and shaft dimensions if possible. MR Industrial Accessories LLC will identify the compatible alternative from the lines it supplies.
