The LINK-BELT PLB FD series is a 4-bolt flange mounted bearing unit that integrates the bearing and housing into one assembly for direct bolting to a flat surface. It supports rotating shafts where a firm, aligned mounting is required, and the flange spreads the load over four points. MR Industrial Accessories LLC supplies this line to customers throughout the United States and Latin America.

The part number breaks down into meaningful blocks. PLB denotes the flange housing family, FD specifies the fastening and sealing type, and the digits that follow indicate size and bearing dimension. For instance, PLB6839FD8 and PLB6847FD8 belong to the same series but differ in shaft diameter; PLB6855FD8 and PLB6863FD8 follow the same pattern. The trailing 8 marks variants within a given size. Supplying the complete part number ensures exact identification.

Typical applications include belt conveyors, bucket elevators, mixers, mills and process equipment in food, chemical and aggregate plants. The 4-bolt flange enables mounting onto sheet metal or structural steel without machining a housing seat, which simplifies field replacement. These units are often chosen where the shaft needs a rigid, low-profile support.

When selecting a unit, consider shaft diameter, the sealing required by the operating environment, and the radial and axial loads of the equipment. During installation, place the flange on a clean, flat surface, tighten the four bolts in a cross pattern, and check shaft alignment before rotating. Proper lubrication and correct internal clearance are key to service life; in dusty or humid conditions, specify enhanced sealing and monitor grease condition.

For interchangeability, compare flange mounted bearing units by shaft size, hole spacing and sealing type rather than part number alone. LINK-BELT is a well-known reference in this family, and many series have direct equivalents in other lines. If you are replacing an existing unit, provide the old part number or the flange dimensions and we will identify a compatible alternative.
