UCT 214 (Y/UCT 214)

Take-up cast iron unit with insert ball bearing, set screw locking and extended inner ring, JIS

Take-up ball bearing units, consisting of an insert bearing based on a sealed deep groove ball bearing mounted in a grey cast iron housing.

Typically mounted in take-up frames, the unit has an inner ring extended on both sides and is locked by tightening two set screws on the inner ring, which makes it easy to mount. Units with designation suffix /H feature a 120° angle of separation between the set screws that contributes to a higher stability and a better load balance.

  • Designed for an alternating rotation
  • Quick and easy to mount onto the shaft
  • Accommodate static initial misalignment
  • Long service life
  • Reduced noise and vibration levels
