Air-actuated rotary pull-back collet chuck for stable 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 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 and repeat positioning 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 and pull-back clamping action 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.
