LINK-BELT series 6600 4-bolt flange bearing housings are mounted units that combine an insert bearing with a round flange housing, designed to secure drive shafts to flat structures. They are used when the shaft must sit perpendicular to the mounting surface and rigid fastening with four anchor points is required. MR Accesorios Industriales sells this line, backed by technical experience in the field.

The PLB…M…FR designation is read in blocks: PLB identifies the flange housing family; the two digits that follow indicate the insert bearing size; the M in the middle indicates how the insert locks onto the shaft; and FR corresponds to the four-bolt flange. The part numbers in the series share series 6600 and differ in the shaft diameter they accommodate. Understanding this structure lets you order the exact part number.

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, meatpacking and cement industries, where mounting on sheet metal or profile structures makes maintenance and cleaning easier. The four-bolt flange distributes loads evenly and allows the shaft to be aligned accurately before tightening the bolts.

To select the right housing, check the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. Series 6600 accepts inserts with different sealing systems; in dusty or damp environments, reinforced lip seals are the better choice. During mounting, make sure the support surface is clean and flat, and that the four bolts are tightened in a cross pattern so the flange is not distorted. Lubrication must be renewed according to the duty cycle.

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