JAB-40 Pneumatic Collet Chuck Clamping Test
The JAB-40 is mounted on a test fixture with two air lines connected. The operator handles the test piece at the front opening. The close view shows the gripping entrance and air connections. It is a useful view of access around the installed chuck.


How the grip works
JAB is a front-push pneumatic rotary collet chuck. Air pressure actuates the internal mechanism through the matching collet. It opens and closes the grip while the chuck supports rotary work. The product page covers turning, grinding and other rotary setups. Match the collet to the chuck model, gripping profile and part diameter.
Front-push actuation suits operations that need a consistent part projection. Keep the locating face clean and seat the part at its intended stop. Leave clearance between the air connections, rotating parts and machine guarding. The linked product page lists model data and mounting dimensions.

What to check in this setup
- Identify the clamp and release air circuits.
- Check access for loading and unloading.
- Check the installation after changing the collet.
