Air or hydraulic rotary collet chuck with force-release structure for controlled clamping and release.
Air / Hydraulic Rotary Collet Chuck — Force Release
KORRETTO air / hydraulic rotary collet chuck with force release is used for round-part clamping where the collet must clamp and release reliably during rotary operation. The force-release structure helps separate this product from ordinary front-mount collet chucks or passive collet systems. Selection should confirm actuation method, collet size, release stroke, spindle layout, maximum speed and required clamping force.
Product Overview
This rotary collet chuck can be configured for air or hydraulic actuation depending on the machine layout and clamping force requirement. The force-release structure is important when the process requires reliable release rather than depending only on spring force or passive movement.
This page covers the air / hydraulic rotary collet chuck with force-release structure only. It should not be merged with rubber-flex collet chucks or ordinary pneumatic jaw chucks.

FAQ
What is a force-release rotary collet chuck?
It is a rotary collet chuck with a structure designed to release the collet through controlled air or hydraulic actuation.
Can this product use air or hydraulic actuation?
Yes. The correct actuation method depends on required clamping force, machine layout, cycle time and available power source.
Is this the same as a front-mount collet chuck?
No. A front-mount collet chuck describes an installation style. This page focuses on rotary collet clamping with force release.
What information is needed for selection?
Provide the workpiece drawing, collet range, actuation method, mounting interface, release stroke, target speed and clamping force requirement.
Is this a rubber-flex collet chuck?
No. Rubber-flex collet chucks are handled under a separate product category.
