Air-actuated rotary pull-back collet chuck for stable axial seating and round-part clamping.
JAD Air Rotary Pull-Back Collet Chuck
KORRETTO JAD air rotary pull-back collet chuck uses air actuation and pull-back clamping action for rotary collet workholding. It is suitable for round parts, shafts and sleeves that need repeat clamping, stable axial seating and compact spindle-side installation. This page covers the JAD pull-back series only and should not be mixed with front-push, hydraulic rotary or passive collet chuck series.

Product Overview
The JAD air rotary pull-back collet chuck is selected when the workpiece needs to be pulled back toward the locating face during clamping. This helps improve axial seating, repeat positioning and pull-back collet workholding for suitable round parts, shafts and sleeves.
Selection should confirm workpiece diameter, collet type, pull-back stroke, air pressure, mounting interface, maximum speed, clamping force and the required locating method.

FAQ
What is the JAD air rotary pull-back collet chuck used for?
It is used for rotary collet clamping where air actuation, pull-back clamping action and stable axial seating are required.
What does pull-back clamping mean?
Pull-back clamping draws the collet or workpiece toward the locating side during clamping, helping support axial seating and repeat positioning.
Is this the same as a front-push collet chuck?
No. JAD is a pull-back collet chuck series. Front-push and passive collet chucks are separate structures.
What information is needed for selection?
Provide the workpiece drawing, clamping diameter, collet type, pull-back stroke, air pressure, mounting interface, target speed and clamping force requirement.
When should I choose a pull-back collet chuck?
Choose it when the process needs round-part collet clamping with improved axial seating against a locating face.
