Rotary Hydraulic Collet Chuck - JHB

The rotary hydraulic collet chuck is a high-performance tool designed with an integrated steel structure treated through heating, ensuring exceptional strength, stability, and durability. Its bearings are optimized to avoid overload, maintaining low temperature rise and extending service life.
Featuring a two-way power mechanism, the chuck ensures forced opening and secure clamping without risk of sticking. In case of air supply interruption, the system automatically self-locks for enhanced safety. The chuck directly connects to the spindle via a flange, simplifying and speeding up installation. Additionally, it is compatible with three-point combination air valves, enabling seamless integration with the machine tool control system.
The quick replacement of the tube clip allows for efficient product transitions, making it highly versatile. The oil pressure clamping mechanism delivers substantial force while maintaining low relative speed, ensuring precision and reliability during operation. It is particularly suitable for reprocessing tasks and applications.
