LINK-BELT series 6600 4-bolt flange housings are mounted units that combine an insert bearing with a circular flange housing, designed to fix transmission shafts to flat structures. They are used when the shaft must be perpendicular to the mounting surface and rigid support with four anchoring points is required. MR Accesorios Industriales supplies this line as an official brand, with the technical backing of more than 80 years in the field.

The designation PLB#M#FR is read in blocks: PLB identifies the flange housing family; the two digits that follow indicate the insert bearing size; the intermediate M indicates the insert mounting type on the shaft; and FR corresponds to the 4-bolt flange. For example, PLB68M65FR and PLB68M70FR share the 6600 series and differ in the shaft diameter they accommodate. Knowing this structure allows you to request the exact code or the compatible alternative.

These housings are used in belt conveyors, bucket elevators, mixers, mills and process equipment in food, chemical and aggregate plants. In Argentina they are common in the oilseed, meat and cement industries, where mounting on sheet metal or profile structures facilitates maintenance and cleaning. The 4-bolt flange distributes loads evenly and allows the shaft to be aligned accurately before tightening the bolts.

To select the correct housing, check the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The 6600 series accepts inserts with different sealing systems; in dusty or humid environments, reinforced lip seals should be chosen. During assembly, make sure the mounting surface is clean and flat, and that the four bolts are tightened in a cross pattern to avoid deforming the flange. Lubrication must be renewed according to the duty cycle.

Regarding interchangeability, 4-bolt flange housings are available from several brands with standardized dimensions, but tolerances and housing materials may vary. When replacing a LINK-BELT unit with another brand, compare the shaft diameter, the flange diameter, the bolt hole spacing and the overall height. If space is limited, the 6600 series offers compact alternatives. MR Accesorios Industriales advises you to find the right equivalent without compromising performance.
