GN 918-GVB Eccentric Cams Screw from the Back

Eccentric cams GN 918 allow the rapid and secure clamping and releasing at a relatively large clamping range and with high clamping force. The cam offers the advantage that the clamping force remains constant in every angular and is self-locking at the same time. The ball levers of types KV / KVS / KVB and GV / GVS / GVB 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.

Version with Threaded Bolt

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.

Version with Screw from the Operator‘s Side

Fastening via screw from the operator’s side bridges a larger clamping range. A sufficiently large screw-in depth t is necessary to safely absorb the screw forces. The centering step of the thrust washer provides protection from impermissible lateral forces on the socket cap screw.

Version with Screw from the Back

Fastening the screw from the back allows the use, if there is no thread in the surrounding structure. The heavy duty washer absorbs and transfers the resulting screw forces. The centering step of the thrust washer provides protection from impermissible lateral forces on the socket cap screw.
