A four-bolt flange housing from the LINK-BELT B22400 series holds an insert ball bearing and bolts directly onto a flat wall, frame or cast surface. This makes it a practical choice for conveyor, mixer, fan and agricultural drive points where the bearing has to sit square and stay sealed. The FBB224M code covers several shaft sizes, so the same housing family fits a range of equipment.

Reading the code: FBB stands for the 4-bolt flange housing, 224 points to the B22400 series, and M describes how the unit is fixed. The two digits after M give the shaft diameter in millimeters, so FBB224M60H takes a 60 mm shaft, FBB224M65H a 65 mm shaft, FBB224M70H a 70 mm shaft and FBB224M75H a 75 mm shaft. The closing H identifies the insert and sealing arrangement. Once you know this pattern, ordering the right unit becomes straightforward.

Typical duty covers belt and chain conveyors, bucket elevators, mixers, dryers, centrifugal fans and similar process equipment, including food, cement, mining and aggregate plants where dust and moisture are present. Mounting on a wall or frame with a flat face keeps alignment simple, and the four-bolt pattern allows the unit to be removed without disturbing the rest of the assembly.

Selection comes down to shaft diameter, the nature of the load (radial, axial or combined) and the working environment. The insert seal determines how well the unit handles dust, water or chemical exposure, so a version with an extra seal makes sense in harsh conditions. Use the lubricant specified by the manufacturer and renew it according to the duty cycle. During installation, seat the flange flat and tighten the four bolts evenly to prevent distortion and keep the shaft aligned.

Mounted housings in the B22400 series can be swapped between brands when the flange standard and shaft diameter line up. Compare the flange outside diameter, the hole spacing, the shaft size and the insert fixing method before substituting one unit for another; if those dimensions agree, an equivalent housing will usually work.
