UCF 315-48 (Y/UCF 315-48, UCF 315-300)

Square flanged ball bearing unit with set screw locking, cast iron housing, JIS

These square flanged ball bearing units are compliant with Japanese Industrial Standards (JIS).

They consist of an insert bearing, with an extended inner ring and set screw locking, and are suitable for applications where the direction of rotation is constant or alternating. The bearing is mounted in a cast iron housing, which can be bolted to a machine wall or frame. Ball bearing units can accommodate moderate initial misalignment, but normally do not permit axial displacement.

  • Resist high levels of contamination
  • Designed for high temperatures and speeds
  • Accommodate relatively heavy loads
  • Cost-effective
