A UCPA foot-mounted pillow block pairs a cast iron housing with a PEER insert bearing. Two bolts hold it to a flat surface, and the insert accepts slight angular misalignment, which helps on lines where quick installation, dust and moisture protection matter. Light and medium-duty drives in plants, workshops and production areas are the usual home for this assembly.
Reading the code: UCPA tells you it is an insert-bearing pillow block, and the digits that follow — 201 through 208 — step up with the bearing and shaft size. Shaft diameters run 12 mm, 15 mm, 17 mm, 20 mm, 25 mm, 30 mm, 35 mm and 40 mm, so a UCPA205-25mm takes a 25 mm shaft. Higher numbers mean larger shafts.
Typical installations include conveyors, belts, elevators, mixers, fans, pumps and farm equipment, and they show up in food processing, cement, tanning and metalworking operations where grit or damp air is present. Grease can be added through the housing's lubrication channels while the unit stays in place, and the insert's contact seals hold grease in while keeping contaminants out.
Choosing a size means checking shaft diameter, radial and axial load, and site conditions. Bolt the housing to a flat surface with two fasteners and line up the shaft before final tightening. The insert tolerates a small amount of angular misalignment. Add grease on a regular schedule, inspect the seals when abrasive dust is present, and during installation avoid hammering on the insert and confirm the outer ring sits properly.
UCPA units interchange with other brands built to the same mounting standard, so a part number from a different supplier can often be matched to an equivalent. Send either the complete part number or the shaft size and we will quote what fits. PEER bearings and other options are available through MR Industrial Accessories.

Frequently asked questions
- What does the UCPA code tell me?
- It identifies a pillow block that holds an insert bearing: U for the insert series, C for the cast iron housing, P for the foot shape and A for the fastening style. The trailing number gives the bearing and shaft size.
- How do I pick the right size for my shaft?
- Measure the shaft where the bearing sits. That millimeter value appears in the part number, so UCPA205-25mm fits a 25 mm shaft. If you are unsure, send the measurement and we will quote the exact number.
- Does the UCPA pillow block take grease?
- Yes. Lubrication channels in the housing let you regrease the insert without taking it apart. Use quality grease at a frequency that matches your conditions, and check the seals where dust or moisture is present.
