Tilt-Lock Idler Chucks are designed as companion chucks to Flange, Shoulderless, or Dualock Chucks. Dimensional wise, they are similar to the Flange model, but do not have teeth or retaining bands. The Idler Chuck is recommended in operations where torque requirements are satisfied with the use of only one regular Tilt-Lock Chuck on the shaft. The Idler Chuck serves to hold lateral roll drift and assists in assuring concentricity on the running roll.
