The SKF UCFB Y-bearing pillow block unit is a mounting unit that combines a split cast iron housing with a Y-bearing insert. It is used to support rotating shafts on flat structures, with the advantage that the housing opens and allows the bearing to be replaced without disassembling the shaft. It is a practical solution for transmission and transport equipment in industrial plants.
The UCFB designation identifies a split flanged Y-bearing pillow block. The letters UCFB correspond to the split housing series with mounting holes; the number that follows, as in UCFB 208, indicates the size of the insert bearing and the main dimensions of the unit. The higher that number, the larger the shaft diameter it accepts. To choose the correct part number, the shaft diameter must be cross-referenced with the SKF catalog dimension table.
These pillow blocks are used in belt conveyors, bucket elevators, mixers, mills, conveyor belts and process equipment in the food, chemical, cement and aggregate industries. In Argentina they are common in animal feed plants, meat processing plants and waste treatment plants. The cast iron housing withstands weather and dust, and the insert bearing comes lubricated and sealed from the factory to work in environments with moderate dirt.
To select the pillow block, verify the shaft diameter and the load type: radial, axial or combined. The UCFB series accepts moderate radial and axial loads. During mounting, make sure the support surface is flat and clean, and align the mounting holes. The split housing facilitates mounting and dismounting without moving the shaft. Check the insert sealing: if there is fine dust or liquids, additional sealing is advisable. Lubrication is done through the built-in grease fitting, with general-purpose lithium grease.
SKF UCFB pillow blocks are interchangeable with other brands that manufacture equivalent units under standards such as ISO 3228. When replacing, compare the housing dimensions, the hole distance and the shaft diameter. If space allows, you can substitute a unit from another brand with the same numeric part number. At MR Accesorios Industriales we sell SKF as an official brand and can advise you on the equivalence with other alternatives on the market.

Frequently Asked Questions
- What does UCFB mean in a SKF pillow block?
- UCFB is the designation of a split flanged Y-bearing pillow block. The abbreviation indicates a split housing with mounting holes, and the number that follows, such as 208, defines the size of the insert bearing and the shaft diameter it accepts.
- How do I know what size of UCFB pillow block I need?
- You have to measure the shaft diameter where the insert bearing is mounted. That value is cross-referenced with the SKF catalog dimension table to choose the corresponding UCFB part number. If you have doubts, send us the measurement via WhatsApp and we will advise you.
- Can only the insert bearing be replaced without changing the pillow block?
- Yes, the split housing allows it to be opened and the insert bearing replaced without dismounting the pillow block from the structure. It is one of the advantages of this design. Check that the replacement insert is compatible with the diameter and locking type.
