SEALMASTER RFB series flange units combine a bearing and its housing in one assembly that bolts to a flat face. They support shafts in equipment that needs firm front fastening and straightforward installation. MR Industrial Accessories LLC supplies this line to customers across the United States and in several Latin American countries, and can help you identify the right part number for your application.

The RFB code follows a simple pattern: letters denote the flange housing family, and the number that follows gives the size. References such as RFB-103, RFB-104, RFB-106, RFB-107, RFB-108, RFB-110, RFB-111 and RFB-112 all share the same mounting style; the numeric suffix separates housing sizes and the shaft each one accepts. When selecting, the complete part number is the key piece of information.

These units appear in power transmission and conveying equipment with horizontal or front-facing shafts: conveyor belts, elevators, mixers, blowers, pumps and process machinery. In food, chemical, cement and meat processing plants, as well as metalworking shops, they are chosen for their robust construction and simple replacement. The 4-bolt flange fastens to a flat face of the equipment and keeps the shaft aligned with the assembly.

Selection depends on shaft diameter, load type and operating environment. The 4-bolt flange needs a flat mounting surface with aligned holes; tighten bolts in a cross pattern and verify shaft alignment before start-up. Lubrication and sealing have a direct effect on service life, so in dusty, wet or frequently washed areas, specify the variant with suitable sealing. Under vibration, check the fit at regular intervals.

When comparing flange units across brands, cross-reference by shaft diameter, number of bolts, center-to-center distance and bearing type inside. A similar part number alone is not enough. If you are replacing an existing unit, send the part number stamped on the housing or the flange dimensions, and we will identify the compatible alternative within the SEALMASTER line.
