LINK-BELT series 6600 4-bolt flange bearing housings are mounted units that pair an insert bearing with a round flange housing, holding a shaft perpendicular to a flat mounting surface. Four anchor points provide rigid fastening where the shaft must sit square to the structure. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the US, Canada, Mexico and South America.

The PLB…M…FR code breaks into sections. PLB marks the flange housing family, the two digits after it give the insert bearing size, the M in the middle shows how the insert grips the shaft, and FR stands for the four-bolt flange. Every part number in the series shares series 6600 and differs by the shaft diameter it takes. Reading the code this way helps you order the exact unit.

Typical installations include belt conveyors, bucket elevators, mixers, mills and process equipment in food, chemical and aggregate plants. Mounting on sheet metal or profile structures simplifies maintenance and cleaning. The four-bolt flange spreads the load across the mounting surface and lets you align the shaft accurately before final tightening.

When selecting a housing, confirm the shaft diameter, whether the load is radial, axial or combined, and the surrounding conditions. Series 6600 accepts inserts with different sealing systems; for dusty or damp areas, reinforced lip seals are the better option. At installation, keep the support surface clean and flat, then tighten the four bolts in a cross pattern to avoid distorting the flange. Renew lubrication according to the duty cycle.

Several brands offer 4-bolt flange housings in standardized dimensions, but tolerances and materials can differ. If you replace a LINK-BELT unit with another brand, compare shaft diameter, flange diameter, bolt hole spacing and overall height. Where space is tight, series 6600 includes compact options. Our team can help you find a suitable equivalent without compromising performance.
