UCF Series Bearings – Features and Applications

The UCF series is a popular type of mounted ball bearing unit, specifically a square flanged unit.

UCF stands for:

UC = Insert ball bearing with set-screw locking (wide inner ring + spherical outer diameter)
F = Square flange housing (cast iron housing with a square flange and four mounting bolt holes)

Typical Applications

UCF bearings are ideal for supporting shafts that need to be mounted on vertical or side surfaces. Common uses include:

Wall- or panel-mounted shafts in machinery frames
Conveyor systems (side-mounted rollers or drive shafts)
Agricultural equipment
Food processing and packaging machinery
Textile machinery
Fans, blowers, and air-handling units (side-mounted)
Pumps and gearboxes where the shaft exits a vertical surface
Mixers, agitators, and general industrial equipment requiring compact flange mounting
