Steep Taper Grippers SSKE-KH
SSKE-KH grippers are designed for applications requiring a shorter drawbar stroke.
Steep Taper Grippers SKR
The SKR gripper offers the unique capability of holding a tool with low force before the tool is clamped. This means that the spindle can pull away from the tool changer before tool clamping takes place (a key feature when fast tool change time is needed).
Steep Taper Grippers SSK-JBS
SSK gripper are primarily designed for drawing in and ejecting steep taper tooling provided with retention knobs internationally standardized as per DIN, ANSI, MAS, JIS and ISO which allow fast automatic tool changes. SSK grippers are not only suitable for clamping tools, but also workpieces or workpiece holders and pallets on machining centers, milling machines, boring machines, grinding centers, special purpose machines, and handling systems.
Steep Taper Grippers SSKF
With an easy-to-machine spindle contour, BERG Spanntechnik SSKF gripper is designed for cost-sensitive applications.
Steep Taper Grippers SSKE
Based on the popular SSK design, BERG Spanntechnik SSKE grippers use a common spindle contour for all retention knob standards, greatly simplifying design and production requirements for spindle manufacturers.
SSKES grippers are dimensionally the same as the SSKE series, except are designed with additional features for high-speed operation.
