The SEALMASTER SFMH-T Y-bearing with insert bearing is a 4-bolt flange mounted unit that combines a cast iron housing with a self-aligning insert bearing. It is used to support rotating shafts in equipment where the flange is fixed to a flat surface, such as conveyor belts, mixers, fans and agricultural machinery. MR Accesorios Industriales supplies this line with technical advice to select the correct size.

The designation SFMH-T reads as a family of square 4-bolt flange brackets. The letters SFMH identify the construction type, the T indicates the sealing variant and the number that follows — as in SFMH-20RT — corresponds to the shaft diameter for which the insert is machined. The suffix RT indicates the type of seal or sealing of the insert bearing. This code defines the complete unit: housing plus bearing.

In Argentine industry these brackets appear in belt conveyors, bucket elevators, screens, mixers and process equipment. They are also found in food, cement, mining and aggregate processing plants, where the 4-bolt flange allows mounting onto sheet metal or structure without machining. The cast iron housing withstands radial loads and some axial thrust, and the self-aligning insert absorbs small shaft misalignments.

To choose the bracket, check the insert shaft diameter and the flange hole pattern. The RT seal protects against dust and moisture; in environments with water or frequent washing, additional protection is advisable. During mounting, rest the flange on a clean, flat surface, tighten the bolts in a cross pattern and check that the shaft turns without effort. The insert is lubricated through the built-in fitting, with the grease recommended for the working temperature.

SEALMASTER mounted brackets are interchangeable with other 4-bolt flange brands that share the shaft diameter and mounting pattern. Interchangeability depends on the flange dimensions and the type of insert-to-shaft fixing — set screw, eccentric or taper — not only on the code. If you need to replace an existing unit, send us the code stamped on the housing or the flange dimensions and shaft diameter.
