The LINK-BELT 6600 series pillow block is a split cast iron housing designed to support a shaft in power transmission systems. It mounts on a base and provides an additional support point separate from the drive machine, making it suitable for conveyors, mills, pumps, and process equipment. MR Industrial Accessories supplies this line and can help you identify the correct part number based on shaft diameter and mounting configuration.
The part number is structured in blocks. The prefix PLB denotes the split pillow block family. The number that follows indicates the housing size. The letter M refers to the mounting type or variant. The final number is the shaft diameter in millimeters or its equivalent within the series. For instance, PLB68M40R and PLB68M45R share the same housing body but differ in shaft diameter; PLB68M60R and PLB68M65R follow the same pattern. The suffix R identifies the replacement version or the seal material, as applicable.
These housings are common in belt and chain conveyors, bucket elevators, mixers, flour mills, food processing plants, and packaging lines. They also appear in mining, cement, and aggregate equipment, where dust and load are demanding. As pillow blocks, they allow the shaft to be aligned independently of the main frame and accommodate minor misalignment. MR Industrial Accessories supplies them for replacement and new projects across the United States and several Latin American countries.
When selecting a housing, consider the shaft diameter, the radial and axial loads it must carry, and the sealing required for the environment. In dusty or wet conditions, a lip seal or double lip seal is recommended. In high-temperature areas, check the lubrication and the bearing internal clearance. Mount the housing on a flat, rigid surface, tighten the anchor bolts properly, and align the shaft before final fastening. Renew lubrication according to the duty cycle and grease type.
Pillow blocks can be interchanged with other brands that use the same mounting standard and shaft diameter. When requesting a quote, compare the center height, hole spacing, and mounting type, not just the part number. A compatible alternative within the same series or from another brand we supply can be evaluated. Interchangeability depends on the critical mounting dimensions and the load capacity of the housed bearing matching.
To request a quote, send the full part number from the equipment or housing plate via WhatsApp, for example PLB68M70R or PLB68M80R. If you do not have it, provide the shaft diameter, a photo of the mounting, and the main dimensions. MR Industrial Accessories will quote the LINK-BELT housing you need or suggest a compatible alternative. We handle technical inquiries and orders from throughout the United States and Latin America.

Frequently asked questions
- What does the part number PLB68M40R indicate?
- PLB stands for split pillow block, 68 is the housing size, M is the mounting variant, and 40 is the shaft diameter in millimeters. The final R distinguishes the replacement version or seal type. Send us the full part number and we will quote it.
- How do I determine which pillow block fits my machine?
- You need the shaft diameter, radial and axial loads, and the working environment. With that information we can define the size and sealing. If you have the original part number, send it via WhatsApp and we will confirm the correct option.
- Are LINK-BELT housings interchangeable with other brands?
- Yes, provided the center height, hole spacing, shaft diameter, and load capacity match. A similar part number alone is not sufficient. At MR we help you compare the critical dimensions before quoting.
