The LINK-BELT PLB FD series housing is a 4-bolt flange mounted bearing unit: a compact unit that combines the bearing and the housing in a single piece, ready to be fastened onto a flat surface. It is used to support rotating shafts in equipment where mounting must be firm and aligned, with the flange distributing the load across four points. MR Accesorios Industriales supplies this line as an official brand in Buenos Aires, Argentina.

The designation of the PLB FD series is read in blocks: PLB identifies the flange housing family, FD indicates the type of fastening and sealing, and the numbers that follow correspond to the size and the bearing dimension. For example, PLB6839FD8 and PLB6847FD8 share the series but change the shaft diameter; PLB6855FD8 and PLB6863FD8 follow the same logic. The final suffix 8 distinguishes variants of the same size. With the complete part number it is identified without ambiguity.

These housings are found in belt conveyors, bucket elevators, mixers, mills and process equipment in food, chemical and aggregate plants. In Argentina they are common in the oilseed industry, in grain processing plants and in packaging lines, where the shaft needs a rigid, low-profile support. The 4-bolt flange allows mounting onto sheet metal or structure without machining the housing seat, which simplifies field replacement.

To choose well, look at the shaft diameter, the type of sealing required by the environment and the radial and axial load of the equipment. During mounting, rest the flange on a clean, flat surface, tighten the four bolts in a cross pattern and verify shaft alignment before rotating. Correct lubrication and suitable internal clearance determine service life: if the equipment works with dust or humidity, prioritize reinforced sealing and check the condition of the grease.

As for interchangeability, flange mounted bearing units are compared between brands by shaft size, hole spacing and type of sealing, not only by part number. LINK-BELT is a reference in this family and many series have direct equivalents in other lines. If you need to replace an existing unit, send us the old part number or the flange dimensions and we will indicate the compatible alternative.
