LINK-BELT Z series pillow blocks are mounted units that pair an insert bearing with a pillow block housing. They bolt to a flat surface and support rotating shafts, with lubrication built in. MR Industrial Accessories supplies this line and helps you match the unit to your shaft size and load.

In the Z series, the shaft size comes first and the letter Z closes the code. Part 21214Z fits a 2 1/4 inch shaft; 21215Z fits a 2 3/16 inch shaft. Shaft diameter changes from one part number to the next, and the Z suffix marks the construction variant in the pillow block family. Within a series, the leading digits point to the unit type and nominal shaft diameter, while the trailing number reflects the housing configuration, which also varies by part number. Send the full reference and we will identify the equivalent.

Typical installations include belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and process equipment in food, chemical and aggregate plants, as well as industrial fans and low to medium speed drive shafts. The pillow block housing mounts on steel structures or concrete bases with four bolts.

When selecting a unit, look at shaft diameter, radial and axial loads, and the surrounding conditions. A flat, rigid base prevents distortion that would alter internal clearance. Use the lubricant specified by the manufacturer and renew it according to the duty cycle. For dusty or humid areas, pick a variant with suitable sealing. Align the pillow blocks with each other; angular or parallel misalignment speeds up wear on both bearing and housing.

LINK-BELT Z series pillow blocks interchange with other brands of mounted pillow blocks that share the same basic dimensions and shaft diameter.

MR Industrial Accessories supplies the LINK-BELT line and can advise on interchangeability. What matters is matching the mounting dimensions and the insert bearing type.
