The SEALMASTER SFMH-T is a four-bolt flange unit that pairs a cast iron housing with a self-aligning insert bearing. It supports rotating shafts where the flange bolts to a flat surface, a common setup on conveyors, mixers, fans and farm equipment. MR Industrial Accessories LLC supplies this line and helps you match the right size to your application.
Reading the code: SFMH denotes the square four-bolt flange bracket family, T is the sealing variant, and the number that follows — for example, SFMH-20RT — gives the shaft diameter the insert is bored for. The RT suffix identifies the insert bearing's seal type. Together, these characters specify the complete unit: housing and bearing.
These brackets are used in belt conveyors, bucket elevators, screens, mixers and process equipment, as well as in food, cement, mining and aggregate plants. The four-bolt flange mounts directly to sheet metal or structural steel without machining. The cast iron housing takes radial loads and some axial thrust, while the self-aligning insert compensates for minor shaft misalignment.
When selecting a bracket, confirm the insert shaft diameter and the flange hole pattern. The RT seal guards against dust and moisture; for washdown or wet areas, extra protection is recommended. During installation, set the flange on a clean, flat surface, tighten the bolts in a cross pattern, and verify the shaft turns freely. Lubricate the insert through its built-in fitting using grease suited to the operating temperature.
SEALMASTER mounted brackets can interchange with other four-bolt flange brands that share the same shaft diameter and mounting pattern. Compatibility depends on flange dimensions and how the insert locks to the shaft — set screw, eccentric or taper — not just the code. To replace an existing unit, send the code stamped on the housing, or the flange dimensions and shaft diameter.
MR Industrial Accessories LLC supplies the SEALMASTER line and provides selection support. Send the code SFMH-20RT or any SFMH-T series number you need, along with the shaft diameter and a photo of the flange if available, by WhatsApp or email. We reply promptly and can suggest a compatible alternative when required.

Frequently asked questions
- What does the code SFMH-20RT mean?
- SFMH identifies the four-bolt flange bracket; T is the sealing variant; 20 is the insert shaft diameter; and RT is the seal type. This follows the SEALMASTER SFMH-T series nomenclature.
- How do I know if it replaces the bracket I have mounted?
- Compare the shaft diameter, flange hole pattern and insert fixing type. With that information we can confirm whether the SEALMASTER unit is compatible or recommend the best fit.
- Does the insert bearing need maintenance?
- Yes. Lubricate it through the built-in fitting with grease suitable for the temperature and environment. In dusty or moist areas, check the seal condition and refresh lubrication according to the duty cycle.
