JAB-40 Rotary Collet Chuck Speed Test at a 3600 rpm Setpoint
The camera first shows the rotating JAB-40, then the test-machine screen. The setpoint is 3600 rpm. The displayed running speed is about 3601–3602 rpm. These numbers identify the operating point shown in this test; the model data remains on the product page.


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
- Separate set speed from displayed running speed.
- Include the collet and workpiece in the speed selection.
- Record the mounting configuration used for the test.
