SEALMASTER's SRF line covers two-bolt flange bearing units that hold a rotating shaft against a flat mounting surface. Where space is tight and the shaft needs a self-aligning support that carries radial load plus a measure of axial thrust, this style of unit is a common choice. MR Industrial Accessories supplies the SEALMASTER range to maintenance and purchasing teams throughout the United States and in several Latin American markets.
Reading the code: the letters SRF mark a flange housing that takes an insert bearing. In a reference such as SRF-20R, the digits give the shaft size in millimeters or the inch equivalent, and the trailing R tells you which insert configuration and locking method is fitted. Match the shaft diameter and the full code from the nameplate before ordering.
Typical duty covers belt conveyors, bucket elevators, mixers, fans and process lines in food, chemical and materials handling plants. Two-bolt flange mounting keeps installation simple on folded sheet metal and profile frames, which is why the same units turn up on pumping equipment and agricultural machinery.
Selection comes down to three checks: shaft diameter, insert locking style (set screw, eccentric collar or adapter) and the sealing arrangement the environment demands. The flange face should sit flat and the bolts should be drawn down evenly so the housing is not distorted. Align the shaft to the housing to keep extra load off the bearing, and relubricate the insert with lithium or a compatible grease.
SEALMASTER SRF housings can be swapped with other makes of two-bolt flange mounted bearings that use the same shaft diameter and mounting dimensions. Send the complete code along with the shaft dimensions and our team will confirm the equivalent option, so the replacement drops in without touching the machine.

Frequently asked questions
- What does SRF mean in a SEALMASTER housing code?
- SRF denotes the series of two-bolt flange housings that accept an insert bearing. The number after it gives the shaft diameter, and the closing letter R identifies the insert configuration. Send the full code plus the shaft diameter and we will confirm the match.
- How can I check that an SRF housing fits my machine?
- Check the shaft diameter, the flange hole spacing and the insert locking type against your equipment. A photo or the code from the housing you are replacing is enough for us to identify the equivalent reference and quote it.
- What grease does this housing take?
- The insert bearing runs on lithium or compatible grease. How often you relubricate depends on the working conditions, with dirty or damp locations calling for shorter intervals. Do not mix greases with different bases, and follow the equipment manufacturer's schedule.
