Wedge bar chuck with hydraulic compensation

Radial clamping for out-of-round clamping diameters

With this type of chuck, thin-walled workpieces can be clamped purely radially. This results in a large clamping range. On the other hand, this chuck is also suitable for workpieces with short contact surfaces for clamping.

Problem	Properties	Workpieces
Asymmetrical workpiece Clamping force adjustable over a wide range High roundness requirement Non-round clamping diameter Reduce machining operations Thin-walled components	Centric with hydraulic compensation Compensation clamping For non-round clamping ø For thin-walled parts High centring accuracy Number of jaws > 3 Several clamping levels	Brake disc Cam adjustment Disc Flange Gear wheel Hollow shaft Housing Ring Ring - Cone ring Ring - Synchron ring Ring gear

Technical features

Purely radial clamping movement
Centric with hydraulic compensation
Chuck sizes from 160-700 mm
Air system control (optional)
Centrifugal force compensation up to 100% (optional)
Possible for internal and external clamping

Typical applications

Version with quick jaw change

With our quick jaw change, jaws can be changed within seconds, without any tools.
Sintered synchron ring

In spite of an out-of round clamping diameter, the machined diameter is round after just one machining operation
Clamping in two or more clamping levels

For example, cylinder liners can be produced directly from the raw casting to the final accuracy.
