Description
SEALMASTER FBMH-20R belongs to flange mounted bearing, part of our Bearing housings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for FBMH-20R and any equivalents.
The FBMH from SEALMASTER is a flanged mounted bearing unit that supports rotating shafts on flat surfaces. A bolt-on flange body holds an interchangeable insert, so the assembly can be fixed to machine faces, hoppers or frames. Conveyors, mixers and drive equipment commonly use this style where space is tight and the insert needs to be swapped without a major teardown. MR Industrial Accessories LLC supplies the line and helps buyers match the unit to the shaft.
Reading the code helps you order the right piece. FB stands for flange, MH is the mounting series, and the number after the dash gives the shaft size, as in FBMH-20R, either in millimeters or its inch equivalent depending on the standard. The trailing R marks the version that ships with an insert bearing. With that breakdown, a maintenance planner can specify either the complete bracket or the insert alone.
These brackets show up on belt conveyors, bucket elevators, mixers, blowers and packaging lines, as well as agricultural machinery and aggregate plants where dust and moisture are present. Four bolts through the flange secure it to sheet metal or cast iron, which keeps insert replacement simple and avoids pulling the whole shaft.
Selection comes down to three checks: shaft diameter, insert mounting style (set screw or eccentric), and the sealing needed for the environment. At installation, the support surface should be clean and flat, and the bracket aligned with the shaft before the bolts are tightened. Lubrication follows the manufacturer's instructions, and radial play is set through the bearing's own mounting system.
Flange brackets with insert bearings can be interchanged between makers when flange dimensions, shaft diameter and mounting system line up. SEALMASTER is a well-known reference, and equivalents are available. MR Industrial Accessories LLC can point you to a compatible option or source the SEALMASTER unit, with the same mounting quality.

Frequently asked questions
- What does the R at the end of FBMH-20R mean?
- It shows that the bracket comes with a mounted insert bearing, so it is the complete version ready to bolt to the structure. The insert on its own can also be quoted under its own part number.
- How do I confirm the shaft diameter?
- Measure the shaft where the bearing sits and compare it with the number in the designation. FBMH-20R, for instance, fits a 20 mm shaft or its equivalent. If unsure, send the measurement by WhatsApp and we will check it.
- Will this work in dusty or damp areas?
- Flange brackets with sealed inserts are used in tough environments. Where dust or moisture is heavy, versions with extra or labyrinth seals are the better fit. Ask about the sealing options for your application.
