Röhm Stationary Power Chucks SSP

Stationary Power Chucks
SSP

APPLICATION
For stationary centric clamping of workpieces on milling machines or machining centers.

TYPE
Clamping system consisting of a 3-jaw chuck, including an integrated pneumatic cylinder.
Serration 90°.

TECHNICAL FEATURES
- Wedge hook system with pneumatic actuation
- Clamping force can be regulated by changing the pressure

CUSTOMER BENEFITS
» Compact design

» Large variety of applications is possible by using different clamping jaws
» Centric clamping of round and angular workpieces
» High repeatability thanks to sturdy chuck construction and constant clamping force at same pressure
» Purge air connection possible to prevent contamination

Note: Hydraulic actuation on request
