The SKF UCFB Y-bearing pillow block unit pairs a split cast iron housing with a Y-bearing insert, giving you a mounting unit for supporting rotating shafts on flat surfaces. Because the housing opens, the insert can be swapped out without pulling the shaft, which simplifies maintenance on transmission and conveying equipment in industrial plants.
The code breaks down simply: UCFB indicates a split flanged Y-bearing pillow block, the letters standing for the split housing series with mounting holes. The number that follows, as in UCFB 208, sets the insert bearing size and the unit's main dimensions; a higher number means a larger shaft diameter. To pick the right part number, match your shaft diameter against the SKF catalog dimension table.
Typical installations include belt conveyors, bucket elevators, mixers, mills, conveyor belts and process equipment in food, chemical, cement and aggregate operations. The cast iron housing stands up to weather and dust, while the insert bearing arrives lubricated and sealed for environments with moderate dirt.
Selection starts with shaft diameter and load type: radial, axial or combined. The UCFB series handles moderate radial and axial loads. When mounting, keep the support surface flat and clean, align the mounting holes, and take advantage of the split housing to mount or dismount without moving the shaft. Check the insert sealing; in fine dust or liquid exposure, extra sealing is recommended. Lubricate through the built-in grease fitting with general-purpose lithium grease.
SKF UCFB pillow blocks interchange with other brands making equivalent units under standards such as ISO 3228. For replacement, compare housing dimensions, hole distance and shaft diameter. If space permits, a unit from another brand with the same numeric part number can be substituted. MR Industrial Accessories supplies SKF and can advise on equivalents from other options on the market.
For a replacement SKF UCFB Y-bearing pillow block, send the complete part number via WhatsApp or email. We help you identify the correct unit based on shaft diameter and working conditions, and we can also quote the insert bearing separately if that is all you need. The team replies promptly.

Frequently asked questions
- What does UCFB mean in a SKF pillow block?
- UCFB designates a split flanged Y-bearing pillow block. The letters indicate a split housing with mounting holes, and the number that follows, like 208, defines the insert bearing size and the shaft diameter it accepts.
- How do I determine the correct UCFB pillow block size?
- Measure the shaft diameter where the insert bearing mounts, then cross-reference that value with the SKF catalog dimension table to find the matching UCFB part number. If you are unsure, send the measurement via WhatsApp and we will help.
- Can I replace only the insert bearing without changing the pillow block?
- Yes. The split housing opens so the insert bearing can be replaced without dismounting the pillow block from the structure. Verify that the replacement insert matches the diameter and locking type.
