The Link-Belt 3-bolt flange bracket is a mounted bearing unit that fastens to a flat surface through three anchoring points. It is used to support rotating shafts in equipment where side or front mounting is more practical than a foot base. MR Accesorios Industriales supplies this Link-Belt line in Buenos Aires, Argentina, with technical support to choose the correct configuration according to the shaft and load.

The designation of these brackets is read in blocks. The initial letters identify the 3-bolt flange family; the number that follows indicates the nominal shaft diameter; the middle letter defines the locking type of the inner ring to the shaft; and the final letters describe the sealing and unit variants. For example, FB3S231N combines the flange body with a specific shaft diameter and an N-type seal. The full part number provides access to the exact configuration.

In Argentine industry they appear in belt and chain conveyors, mixers, dryers, bucket elevators and packaging lines. They are also found in water treatment equipment, food plants and ventilation systems. The 3-bolt flange allows mounting on folded sheet metal or profile structures, with bolt access from the front, which is useful when side space is limited.

To select the bracket, check the shaft diameter, the locking type and the sealing required according to the environment: dust, humidity or frequent washdowns. During mounting, rest the flange on a clean, flat surface, tighten the three bolts in a cross pattern and check shaft alignment with the drive equipment. Lubrication and internal clearance depend on the unit; follow the Link-Belt catalogue instructions for each configuration.

Flange mounted bearings are interchanged between brands by shaft number, locking type and flange dimensions. It can be replaced by an equivalent unit from another manufacturer, provided the shaft diameter, bolt holes and sealing match. MR Accesorios Industriales will indicate the compatible alternative or manufacture it to measure if needed.
