The P3U2M is a 3-bolt flange mounted unit from Link-Belt that pairs a cast iron housing with a 200 series insert bearing. It holds a rotating shaft against a wall or vertical frame, with the shaft running out perpendicular to the mounting face, which suits equipment where space at the side is tight and alignment needs to stay simple.
Reading the code helps when you order. The P stands for the flange housing style, the digit after it gives the number of bolts, U2 points to the 200 series insert, M identifies the housing, and the two digits that follow are the shaft size in millimeters. The trailing N is the seal designation. So P3U2M17N takes a 17 mm shaft, while P3U2M20N, P3U2M25N and P3U2M30N cover 20, 25 and 30 mm. The 200 series sits in the medium-duty range of the line.
Typical installations include belt conveyors, bucket elevators, mixers, agitators, centrifugal pumps and fans. You will find units like these in food processing, cement, tanneries, water treatment and packaging operations. Bolting the flange to a wall or vertical structure keeps the assembly compact and avoids the footprint a pillow block would need.
Selection comes down to three things: shaft diameter, the direction of the load (radial, axial or combined), and where the unit will run. The N seal handles dust and moderate moisture. For frequent washdowns or fine abrasive particles, plan on extra sealing. The insert arrives pre-lubricated and aligned; seat the flange flat and tighten the bolts in a cross pattern. Misalignment is what shortens insert bearing life.
Units from other makers can often take its place when flange dimensions, shaft diameter and insert fastening style line up. Link-Belt, SKF, NTN, Timken and FYH each use their own naming, but the standardized 200 series dimensions make cross-referencing practical. Confirm the original part number and check the housing dimensions before you swap.

- P is the 3-bolt flange housing, 3 is the bolt count, U2 is the 200 series insert, M is the housing type, 17 is the shaft diameter in millimeters, and N is the seal type.
- Will another brand fit in its place?
- Often yes, provided the flange dimensions, shaft diameter and insert fastening system match. The standardized 200 series allows interchange among Link-Belt, SKF, NTN and FYH, but verify dimensions first.
