Link-Belt PLB…R pillow blocks are mounted pillow block bearing units, designed to support rotating shafts in equipment with moderate loads. They are used in conveyors, agitators, pumps and process machinery where a rigid base and stable alignment are required. MR Accesorios Industriales sells this line and advises you on choosing the right variant according to shaft diameter and mounting type.

The PLB…R designation is read as a family of pillow blocks: the letters PLB identify the construction type, the number that follows defines the size and the final letter R distinguishes the mounting version. In the examples PLB6823R, PLB6824R or PLB6831R, the numeric block changes according to shaft diameter and load capacity. The series is based on the 6600, 7800 and 7900 groups, which bring together different combinations of housing and bearing. To identify your size, send us the complete part number or the shaft diameter.

These pillow blocks are found in food, chemical, cement and aggregate processing plants. Also in belt conveyors, bucket elevators, mixers and centrifugal pumps. In Argentina, they are common in sugar mills, milling plants and packaging lines where a robust unit with easy replacement is needed. The pillow block housing allows mounting the shaft on a flat base and absorbing moderate radial and axial loads, with lubrication that is renewed from the outside.

To select the right pillow block, take into account the shaft diameter, the radial and axial load, and the environmental conditions. If there is dust or moisture, a variant with reinforced sealing is advisable; if the equipment runs fast, check the internal clearance and the type of lubricant. During mounting, rest the base on a clean, flat surface, tighten the bolts in a cross pattern and check alignment with the shaft. Poor alignment shortens bearing life and generates vibration.

Mounted pillow blocks are interchanged between brands by shaft number and housing configuration, but not all part numbers are equivalent. Link-Belt, SKF, Timken or NTN series may differ in center height, hole spacing and mounting type. Therefore, before replacing, compare the critical dimensions and the shaft locking system. MR Accesorios Industriales tells you the compatible alternative.
