GN 927 clamping levers with eccentrical cam are used for rapid clamping and releasing operations. In contrast to a clamping operation utilizing threads, these levers permit torque-free clamping.
The lever has been designed to insure that its movement cannot exceed the maximum clamping position.
There are no loose components since all are assembled and mounted in their correct order.
Advantages of the Type A (adjustable contact plate): The distance between the eccentrical cam and the contact surface is adjustable by means of a fine threaded knurled nut. This permits the maximum clamping force to be set by a simple adjustment. In addition this also permits the selection of a preferred lever position in relation to the clamping lever pin.
With these clamping levers, thrust forces of up to 8 kN can be obtained.
For tapped version, see GN 927.
