The Link-Belt FBB is a 4-bolt flange mounted bearing that holds a transmission shaft against a flat surface, with the shaft set at a right angle to the mounting plane. It suits applications that call for a firm, rigid hold and solid load capacity. MR Industrial Accessories LLC supplies this line to customers across the United States, Canada, Mexico and South America.

Reading the FBB code helps you order the right unit. The letters identify a 4-bolt flange housing, and the digits that follow point to the series and bearing size. The B22400 series sits at the base of this family. The H at the end marks the flange configuration. FBB22439H and FBB22440H, for instance, come from the same series but take different shaft diameters, while FBB22639H and FBB22643H belong to a separate size variant. The simplest way to order is to send the full part number from your equipment, or the shaft diameter if the tag is gone.

You will find these housings on conveyors, mixers, blowers, pumps and process equipment. Flange mounting makes installation and replacement easier in food, cement, paper and bottling plants, and the 4-bolt pattern gives a firm hold on metal plates and structures in agricultural machinery and material handling equipment.

Selection comes down to three things: shaft diameter, load type (radial, axial or combined) and the environment around the bearing. A reinforced seal is worth considering where dust or moisture is present, and high-temperature service calls for a check on lubrication. The support face must be clean and flat, and the 4 holes have to line up with the flange. Proper alignment keeps stress off the bearing and helps it reach its expected service life.

Flange mounted bearings come from several brands, each with its own nomenclature, and interchangeability is not automatic. Compare shaft diameter, hole spacing, overall height and seal type before substituting. When those dimensions line up, a part number from another brand can often stand in for the original. If anything is unclear, send the measurements or the old part number and we will point you to the compatible alternative.
