SFF Wedge Coupling

  • SFF Wedge Coupling

The SFF coupling is ideal for feed shafts on machine tools due to its high torque rating. With robust steel hubs (in a black oxide finish), the SFF offers exceptional torsional stiffness and strength. This design assures accurate shaft rotation with precise control. The flexible element gap also dampens conductive heat transfer from motor to output shaft.

Single and double element configurations are available. Bores can be arranged with clamp, taper-lock, or keyed styles.

  • Maximum allowable torque: 221.27 ft-lbs (800Nm)
  • Bore size range: 0.709” – 3.15” (18mm ~ 80mm)
  • Backlash: Zero
