When a shaft needs support but floor space is tight, a 3-bolt flange bracket from Link-Belt offers a practical answer. This mounted unit anchors to a flat surface at three points, so you can mount it to a wall, frame or folded sheet metal instead of a foot base. MR Industrial Accessories LLC supplies this Link-Belt line to customers across the United States and Latin America, with technical help to match the right configuration to your shaft and load.

The part number tells you most of what you need. The first letters indicate the 3-bolt flange family. The number that follows is the nominal shaft diameter. A middle letter shows how the inner ring locks to the shaft. The final letters cover sealing and unit variants. Take FB3S231N: it pairs the flange body with a specific shaft size and an N-type seal. Always quote the complete code to get the exact unit.

You will see these brackets on belt and chain conveyors, mixers, dryers, bucket elevators and packaging lines. Water treatment equipment, food plants and ventilation systems also use them. The three-bolt pattern lets you bolt through the front, which helps when side clearance is limited. It also works on folded sheet metal or profile structures.

Selection comes down to three checks: shaft diameter, locking type and the sealing needed for the environment. Dust, humidity or frequent washdowns will point you to the right seal. During mounting, set the flange on a clean, flat surface. Tighten the three bolts in a cross pattern, then verify shaft alignment with the drive. Lubrication and internal clearance vary by unit, so follow the Link-Belt catalogue for your specific configuration.

Flange mounted bearings can be interchanged between brands by shaft number, locking type and flange dimensions. An equivalent unit from another manufacturer may work if the shaft diameter, bolt holes and sealing match. MR Industrial Accessories LLC can point you to a compatible alternative or discuss a custom solution if needed.
