Air / Hydraulic Rotary Collet Chuck
A front-mount rotary collet chuck used when the clamping unit must work close to the spindle nose and reduce overhang.
Pneumatic and hydraulic collet chuck solutions for CNC lathe workholding, repeat clamping and small-part production.
Collet Chucks
KORRETTO collet chucks and clamping heads are used when the workpiece is better held by a collet-type mechanism instead of standard chuck jaws. This range includes front-mount pneumatic / hydraulic collet chucks, fixed collet chucks, high-speed pneumatic collet chucks, hydraulic rotary collet chucks, pull-back collet chucks and passive collet chuck units for CNC lathe workholding, bar stock, small parts, fixtures and dedicated machines.
Browse Collet Chuck Series
Select a collet chuck by installation type, actuation method, collet type, workpiece diameter, gripping length, machine interface, speed and required clamping force. Rotary collet chucks are used on spindle or rotary applications; fixed collet chucks are used on stationary fixtures or dedicated stations.
Air / Hydraulic Rotary Collet Chuck with Force Release
Used when normal spring or air release is not enough and the process needs a more positive release action.
Air / Hydraulic Collet Chuck Jaws
Used as supporting components for compatible collet chuck systems. Confirm model and jaw interface before selection.
JH(A)7-44 Air / Hydraulic Rotary Quick Collet Chuck
Designed for faster changeover than standard clamping units. Confirm collet type, machine interface and actuation method.
JAS Pneumatic Fixed Collet Chuck
A fixed-station collet chuck used when the workpiece does not rotate with the spindle.
JHS Hydraulic Fixed Collet Chuck
JHS hydraulic fixed collet chuck for stationary hydraulic clamping. It is not the JAS pneumatic fixed collet chuck and is selected when hydraulic force and repeat positioning are required on a non-rotating station.
JAB Pneumatic Rotary Collet Chuck, Front-Push Type
A pneumatic rotary collet chuck for applications requiring fast actuation and clean air operation.
JAD Pneumatic Rotary Collet Chuck, Pull-Back Type
The pull-back action helps seat the workpiece against a locating surface during clamping.
JAW High-Speed Pneumatic Collet Chuck
Used where speed, repeatability and clean pneumatic actuation are important.
JHB Hydraulic Rotary Collet Chuck
A hydraulic rotary collet chuck for applications requiring more force than pneumatic actuation.
JT-W Passive Collet Chuck
Used where the clamping action is driven by the machine or an external mechanism rather than built-in actuation.
JP Front-Push Passive Collet Chuck
A passive collet chuck option for applications where the push direction and installation space are key selection factors.
How to Select a Collet Chuck
- Rotary or fixed installation
Choose a rotary collet chuck when the unit rotates with the spindle. Choose a fixed collet chuck when the clamping unit is mounted on a fixture or table. - Pneumatic or hydraulic actuation
Pneumatic collet chucks are clean and fast. Hydraulic collet chucks are better when higher clamping force is required. - Front-mount, pull-back or front-push structure
Front-mount designs help reduce overhang. Pull-back designs help seat the workpiece against a locating surface. Front-push designs are used when the machine layout requires push-side actuation. - Collet type, standard and workpiece diameter
Confirm the collet type or standard, clamping diameter, workpiece tolerance and required gripping length before selection. If the customer is replacing an existing 5C, ER or special collet chuck setup, the current collet dimensions and machine interface should be checked before selection. - Speed, force and repeatability
For rotary use, speed, balance, clamping force and repeatability should be checked together with the machine and process.

FAQ
What is a collet chuck used for?
A collet chuck is used to hold round or near-round workpieces with a collet-type clamping mechanism. It is common for CNC lathe workholding, bar stock, small parts and repeat clamping where surrounding contact is preferred.
What is the difference between a collet chuck and a jaw chuck?
A jaw chuck clamps with movable jaws. A collet chuck clamps through a collet or sleeve-type mechanism, usually providing more surrounding contact over the workpiece diameter and often better support for small round parts.
Should I choose a pneumatic or hydraulic collet chuck?
Choose a pneumatic collet chuck for clean air operation and fast clamping when the required force is moderate. Choose a hydraulic collet chuck when higher clamping force is required.
What is a fixed collet chuck?
A fixed collet chuck is mounted to a stationary fixture or table and does not rotate with the spindle. It is often used in dedicated machines or secondary operations.
What is a rotary collet chuck?
A rotary collet chuck is installed on a rotating spindle or rotary unit. It is used for turning or other operations where the workpiece rotates during machining.
What is the advantage of a front-mount collet chuck?
A front-mount design can reduce overhang and make installation or maintenance easier when space around the spindle nose is limited.
What is a pull-back collet chuck?
A pull-back collet chuck pulls the workpiece toward a locating surface during clamping. It is useful when axial seating and consistent length location are important.
Are collet chucks suitable for thin-wall parts?
They can be, depending on wall thickness, material and contact length. Rubber-flex collets or diaphragm chucks should also be reviewed for deformation-sensitive parts.
What information is needed for selection?
Provide the workpiece drawing, diameter range, material, current collet type or standard if available, machine model, spindle or fixture interface, actuation method, speed and required clamping force.
Can one collet chuck hold different diameters?
It depends on the collet type, collet standard and clamping range. Usually, different diameters require different collets, sleeves or matched clamping heads.
Are replacement jaws or accessories available?
Some collet chuck systems use matching jaws, sleeves or accessories. Model compatibility should be confirmed before ordering.
