The NRB series is a hydraulically actuated self-contained Pull Back design for non-rotating applications. The collet is coupled to the built-in piston and is drawn into the tapered seat when the chuck is actuated. Part stops can be mounted inside the chuck body.
CB-NRB Features- Self-contained design with built-in cylinder can be hydraulic or pneumatically operated
- Pull Back design maximizes the efficiency of the clamping system by concentrating the chucking force in the direction of the machine table, in addition to drawing the workpiece against the part stop
- Lubricated-for-life design requires minimal maintenance
- All components hardened and precision ground for highest accuracy and long life
