Link-Belt PLB…R pillow blocks are mounted bearing units that hold rotating shafts in place, suitable for equipment with moderate loads. They appear in conveyors, agitators, pumps and other process machinery where a solid base and consistent alignment matter. MR Industrial Accessories supplies this line and can help you select the correct variant based on shaft diameter and mounting style.

The PLB…R code breaks down into three parts: PLB indicates the pillow block construction, the following number sets the size, and the trailing R shows the mounting version. For instance, PLB6823R, PLB6824R and PLB6831R differ in the numeric block, which corresponds to shaft diameter and load capacity. This series draws from the 6600, 7800 and 7900 groups, each combining housings and bearings in different ways. To pinpoint your size, provide the full part number or the shaft diameter.

You will find these pillow blocks in food, chemical, cement and aggregate processing facilities. They also serve in belt conveyors, bucket elevators, mixers and centrifugal pumps. The housing design allows you to mount the shaft on a flat surface while handling moderate radial and axial loads, and lubrication can be refreshed from the outside.

When choosing a pillow block, consider shaft diameter, radial and axial loads, and the operating environment. In dusty or damp conditions, a variant with enhanced sealing is recommended; for high-speed operation, check internal clearance and lubricant type. During installation, place the base on a clean, flat surface, tighten bolts in a cross pattern, and verify alignment with the shaft. Misalignment leads to vibration and reduced bearing life.

Pillow blocks from different brands can often be interchanged by shaft number and housing configuration, but not all part numbers are direct replacements. Link-Belt, SKF, Timken and NTN series may vary in center height, hole spacing and mounting style. Always compare critical dimensions and the shaft locking method before substituting. MR Industrial Accessories can identify a compatible alternative for you.
