The LINK-BELT pillow block is a split cast iron housing that mounts on a base and supports the bearing in power transmission applications. It is used when the shaft needs an additional support separate from the drive machine, for example in conveyors, mills, pumps and process equipment. MR Accesorios Industriales sells this line and advises you on choosing the correct part number according to shaft diameter and mounting type.

The designation of these housings is read in blocks: PLB identifies the split pillow block family, the number that follows indicates the housing size and the letter M corresponds to the mounting type or mounting variant. The final number indicates the shaft diameter in millimeters or its equivalent according to the series. For example, PLB68M40R and PLB68M45R share the same body but change the shaft diameter; PLB68M60R and PLB68M65R follow the same logic. The suffix R distinguishes the replacement version or the seal material, as applicable.

In Argentine industry, these housings appear in belt and chain conveyors, bucket elevators, mixers, flour mills, food plants and packaging lines. They are also found in mining, cement and aggregate processing equipment, where dust and load are demanding. Being pillow blocks, they allow the shaft to be aligned independently of the main frame and absorb small misalignments. MR Accesorios Industriales sells them for replacement and new projects throughout the country.

To select the housing, take into account the shaft diameter, the radial and axial load it must support, and the type of sealing required for the environment. In applications with dust or moisture, a lip seal or double lip seal is advisable; in high-temperature areas, check the lubrication and the bearing internal clearance. Mounting is done on a flat, rigid surface, with the anchor bolts properly tightened and the shaft aligned before final fastening. Lubrication must be renewed according to the duty cycle and the type of grease.

Pillow blocks are interchangeable with other brands that use the same mounting standard and shaft diameter. When requesting a quote, it is advisable to compare the center height, the hole spacing and the mounting type, not just the part number. A compatible alternative within the same series or from another brand MR sells can be evaluated. Interchangeability depends on the critical mounting dimensions and the load capacity of the housed bearing matching.

To move forward with the quote, send the full part number shown on the equipment or on the housing plate via WhatsApp, for example PLB68M70R or PLB68M80R. If you do not have it at hand, send the shaft diameter, a photo of the mounting and the main dimensions. At MR Accesorios Industriales we quote the LINK-BELT housing you need or point you to the compatible alternative. We handle technical inquiries and orders from all over the country.
