The LINK-BELT 300 series 4-bolt flange bracket is a mounted bearing with a square flange housing and four mounting holes, designed to be mounted on flat machine faces, frames or structures. It is used when the shaft must be perpendicular to the mounting surface and firm, evenly distributed fastening is required. MR Accesorios Industriales supplies this line as an official brand and advises you on choosing the correct size for your application.

The designation of this line is read in blocks: FU identifies the 4-bolt flange bracket, the first number after the letters indicates the housing series —in this case the 300 series— and the letter K indicates the bolt locking type. The final number defines the bearing and shaft size. That is why references such as FU3K27, FU3K31, FU3K35, FU3K39, FU3K47 and FU3K55 coexist: they all share the same flange family and differ in the diameter they accommodate.

These brackets appear in belt and chain conveyors, bucket elevators, mixers, mills, screens and process lines in food, chemical and aggregate plants. In Argentina they are seen in sugar mills, meat processing plants, animal feed plants and mining facilities, where the 4-bolt flange allows mounting on sheet metal or structure without machining a cylindrical seat. They are also used in fans, pumps and transmission equipment that require rigid support and easy replacement.

To select the bracket, start from the shaft diameter and the radial and axial load the equipment will support. Check that the flange has enough space for the four bolts and that the mounting surface is clean and flat. Check the sealing: the radial shaft seal must be correctly oriented to retain lubricant and stop dust or water ingress. During mounting, align the shaft with the bracket, tighten the bolts in a cross pattern and grease according to the duty cycle. Poor alignment shortens bearing life.

As for interchangeability, 4-bolt flange brackets are available from several brands with standardized dimensions, but housing, sealing and locking system details vary. Matching shaft diameter is not enough: you must compare the hole spacing, flange diameter and center height. If you need to replace existing equipment, send us the old part number or a photo of the part and we will indicate the compatible alternative.
