The LINK-BELT B22400 series pillow block is a mounted bearing unit with a flat base, built to support rotating shafts in power transmission systems. It provides a rigid, aligned support point and combines bearing, housing and sealing in one compact assembly. MR Industrial Accessories supplies this line to customers across the United States and Latin America, and can help you select the right configuration for your equipment.
The part number breaks down into distinct elements. PKB denotes the flat-base pillow block family. The 224 refers to the housing size within the B22400 series. The letter M specifies the shaft locking method, and the following number gives the shaft diameter in millimeters. The H suffix indicates a housing construction variant. For example, PKB224M40H fits a 40 mm shaft, while PKB224M65H fits a 65 mm shaft. These sizes cover a broad range of shaft diameters.
You will find these pillow blocks in belt and screw conveyors, bucket elevators, mixers, mills, screens and process equipment across food, chemical, cement and aggregate plants. The flat base mounts easily on profile or sheet metal structures, and the two-bolt anchoring simplifies leveling during installation.
Selection starts with the shaft diameter and the radial load the unit must carry. Confirm there is enough space on the base for the anchor bolts and that the shaft aligns with the rest of the line. During mounting, set the base on a clean, flat surface, tighten the bolts and verify alignment with a straightedge or dial indicator. Lubrication and seal condition are critical: a good seal keeps dust and moisture out, especially where particulate material is present.
When replacing a pillow block from another brand, compare the key dimensions: shaft diameter, distance between base holes, height to shaft center and locking type. The LINK-BELT B22400 series has equivalents in other mounted bearing lines, and direct interchange is often possible. MR Industrial Accessories can identify the compatible alternative for you.
