JAW series air-actuated high-speed collet chuck for round-part clamping.
JAW High-Speed Pneumatic Collet Chuck
KORRETTO JAW high-speed pneumatic collet chuck is designed for rotary collet clamping where fast pneumatic actuation, compact structure and repeat clamping are required. It is suitable for shafts, sleeves and round parts in high-speed machining or special-machine layouts. This page covers the JAW series only and should be kept separate from other pneumatic collet chuck pages.

Product Overview
The JAW high-speed pneumatic collet chuck uses compressed air for clamping and release. It is selected when the workpiece is round, the clamping diameter is stable and the process benefits from fast cycle time and compact collet contact.
Selection should confirm the model, collet range, air pressure, maximum speed, clamping stroke, mounting interface and required repeatability.

FAQ
What is the JAW high-speed pneumatic collet chuck used for?
It is used for high-speed rotary collet clamping of round workpieces with pneumatic actuation.
Is this the same as a general pneumatic chuck?
No. This is a pneumatic collet chuck. It uses collet-style clamping rather than standard jaw clamping.
How is this different from the High-Speed Pneumatic Collet Chuck page?
The JAW series has its own model, drawing and parameter table. Select according to the model, clamping range, speed and machine interface.
What information is needed for selection?
Provide the workpiece drawing, clamping diameter, collet type, air pressure, target speed, mounting interface and required clamping force.
When is a pneumatic collet chuck suitable?
It is suitable when the workpiece is round, the clamping diameter is stable and fast air-actuated clamping is required.
