The FBMH bracket is a SEALMASTER line flanged mounted bearing designed to secure rotating shafts to flat structures. Its flange body with interchangeable insert allows mounting with bolts on front faces of machines, hoppers or frames. It is used in conveying, mixing and drive equipment where a compact, easy-to-replace unit is needed. MR Accesorios Industriales supplies this line with technical advice to select the correct size according to shaft diameter.
The FBMH designation is read as a family of flange brackets with insert bearing. The letters FB indicate flange, MH corresponds to the mounting series, and the number that follows — as in FBMH-20R — indicates the shaft diameter in millimeters or its inch equivalent according to the standard. The final R suffix identifies the version with insert bearing. Knowing this nomenclature allows you to order the exact spare part or the complete unit without ambiguity.
In Argentine industry, FBMH brackets are found in belt conveyors, bucket elevators, mixers, blowers and packaging lines. They also appear in agricultural equipment and aggregate processing plants, where the environment often has dust or moisture. Their flange allows mounting on sheet metal or cast iron with four bolts, facilitating maintenance and insert replacement without disassembling the entire shaft.
To select the correct bracket, verify the shaft diameter, the insert mounting type (set screw or eccentric) and the sealing required according to the environment. During mounting, ensure the support surface is clean and flat, and align the bracket with the shaft before tightening the bolts. Insert lubrication must follow the manufacturer's instructions, and radial play is controlled with the bearing's own mounting system.
Flange brackets with insert bearing are interchangeable between brands if the flange dimensions, shaft diameter and mounting system match. SEALMASTER is a benchmark in the market, and equivalents from other firms exist. MR Accesorios Industriales can indicate the compatible alternative or source the SEALMASTER unit you need, always with the same mounting quality.
