For shafts that need to be supported perpendicular to a mounting surface, the SEALMASTER RFBA series provides a four-bolt flange bearing that centers and secures with four fasteners. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America.
The RFBA code covers a family of four-bolt flange units. In references such as RFBA-103, RFBA-104 or RFBA-110, the digits after the hyphen set the size of the unit and the shaft diameter it fits. A larger number means a larger shaft capacity. Each unit combines a square flange with four mounting holes and a central housing that carries the insert bearing.
Typical installations include conveyors, belts, elevators, mixers, blowers and process equipment where the shaft runs at a right angle to the mounting face. The four-bolt pattern makes anchoring to walls, frames and sheet metal chassis straightforward, and it is also common when older machines are reconditioned because the flange standard is widely used.
Selection depends on shaft diameter, load type, speed and the operating environment. The flange should sit fully against the surface and the four bolts should be tightened evenly to prevent distortion. In dusty, wet or washdown areas, choose an insert with appropriate sealing. Lubrication and internal clearance are set by the insert design and should not be altered. During mounting, align the shaft with the bearing and avoid impacts on the outer ring.
SEALMASTER RFBA units are generally interchangeable with other four-bolt flange mounted bearings of similar dimensions and capacity. Equivalence is not decided by part number alone: check shaft diameter, hole pattern, center distance and insert type. For a replacement, send the part number stamped on the old bearing or the flange dimensions and we will identify a compatible option.
MR Industrial Accessories supplies the SEALMASTER line and can help you define the right RFBA bearing for your equipment. Send the part number, a photo of the flange, or the shaft dimensions and hole spacing by WhatsApp or email. We will respond promptly with a quote and, when needed, suggest an equivalent.

Frequently asked questions
- How do I identify the size of the RFBA bearing I need?
- The number after RFBA indicates the size of the mounted bearing and the shaft diameter. Compare it with the part number stamped on the old bearing, or measure the shaft and the distance between flange holes. With that data we will quote the exact model.
- What is the difference between a flange bearing and a pillow block bearing?
- A flange bearing is bolted to a flat surface with the shaft perpendicular to the support. A pillow block rests on a base with the shaft parallel. The choice depends on the space and how the equipment is built. Both support and align the shaft.
- Are SEALMASTER RFBA bearings available outside the United States?
- Yes. MR Industrial Accessories supplies the SEALMASTER line and serves customers in the United States and several Latin American countries. Send the RFBA part number or your flange dimensions and we will reply promptly with the reference you need or its compatible equivalent.
