Air or hydraulic rotary quick collet chuck for compact, repeat clamping.
JHA7-44 Air / Hydraulic Rotary Quick Collet Chuck
KORRETTO JHA7-44 air / hydraulic rotary quick collet chuck is used for round workpieces that require quick collet clamping in rotary operation. It supports air or hydraulic actuation depending on the machine layout and force requirement. This page covers the JHA7-44 series only and should not be mixed with JAD, JAW, JHB, JHS or JT-W series pages.
Product Overview
The JHA7-44 rotary quick collet chuck is selected when a compact collet chuck is needed for repeat round-part clamping. Its quick-clamping structure helps reduce setup and cycle time when the workpiece size and collet range are stable.
Selection should confirm actuation method, workpiece diameter, collet type, mounting interface, release stroke, clamping force, maximum speed and machine layout.

FAQ
What is the JHA7-44 rotary quick collet chuck used for?
It is used for quick rotary collet clamping of round workpieces such as shafts and sleeves.
Can it use air or hydraulic actuation?
Yes. The suitable actuation method depends on machine layout, required clamping force and cycle time.
Is this the same as JAD or JHB?
No. This page covers the JHA7-44 series only. JAD and JHB are separate collet chuck series.
What information is needed for selection?
Provide the workpiece drawing, clamping diameter, collet type, mounting interface, actuation method, target speed and clamping force requirement.
When is a quick collet chuck useful?
It is useful when similar round parts are loaded repeatedly and the process benefits from fast clamping and release.
