Spiraalvormige excentriek met kogelhandgreep

Eccentric cams GN 918.5 allow the rapid and secure clamping and releasing at a relatively large clamping and with high clamping force. The cam offers the advantage that the clamping force remains constant in every angular position and is self-locking at the same time. The ball levers of types KV and GV feature a positive connection with the eccentric cam by means of a serration. During assembly, the position of the lever can thus be fixed in a position that is favorable for clamping. The use of the thrust washer eliminates the need for special requirements on the execution of the threaded hole, so that it can also be mounted on tables with T-slots, for example.
