Collet Bar Chucks - 
for Deep and Safe Positioning of Long Workpieces

Using the collet bars integrated in the body of the chuck we can set the point of force application relatively far from the point of actual workpiece clamping.
This means that our customers can place long (e.g. wave-shaped) workpieces deep in the chuck and clamp them safely.

The collet bar chucks can also be equipped with a large passage. This means that the workpieces can be loaded via the back of the chuck in the case of complete hollow clamping.

Technical features:

• high clamping forces
• Hollow clamping for tubular workpieces possible 
• fast jaw change (option)

Typical applications:

• long workpieces, for example tubes, shafts, cylinder liners etc.
