A LINK-BELT B22500 series 4-bolt flange bearing housing is a mounted bearing that bolts flat to a surface. It supports a shaft where the mounting has to sit flush against sheet metal or a frame, giving straightforward alignment and rigidity. MR Industrial Accessories LLC supplies this line to customers throughout the United States and in several Latin American countries, and can help you pick the right variant.

The part number is built in blocks, and reading it that way makes selection easier. The leading letters PB mark the 4-bolt flange family. The digits that follow point to the B22500 series and the shaft size. The YFH suffix describes how the insert is sealed and locked. Across the series, each part number differs in shaft diameter and flange size, so the full number is what determines interchangeability.

You will find these housings on belt conveyors, bucket elevators, mixers, screens and process lines, as well as in food, cement, aggregate and wastewater treatment equipment, where a flanged mounting makes cleaning and replacement simpler. They typically sit on folded sheet metal frames or profile structures. Because all four bolts are tightened from the front, the housing works well where there is no room to reach behind the mounting surface.

Start selection with the shaft diameter and the distance between the flange holes. Then match the seal type to the surroundings: dust, water or frequent washdown. The insert needs the correct axial clearance and grease suited to the operating temperature. During installation, tighten the four bolts in a cross pattern and verify shaft alignment with a straightedge or dial indicator. A flange that does not seat properly adds parasitic load and shortens bearing life.

Four-bolt flanged housings from different manufacturers interchange by shaft number and flange dimensions rather than by the complete part number. Lines from SKF, FAG, NTN or Timken can be equivalent, but the seal suffix and locking method may differ. Compare the shaft diameter, the hole center distance and the insert type before substituting. If anything is unclear, send us the old part number and we will identify a compatible option.
