Clamping levers with eccentrical cam GN 927 are used for rapid clamping and releasing. Hereby, contrary to a clamping operation via a thread, these levers permit a torquefree clamping.

The lever has been designed to ensure that its movement cannot exceed the max. clamping force. There are no loose components since they are all assembled and mounted in their correct order. With clamping levers with eccentrical cam GN 927 clamping forces of up to 8 kN can be reached.

The type A with setting nut has the following benefits:

The distance between the lever cam and the clamping surface is adjustable via a fine pitch thread, allowing the clamping position to be set easily with maximum clamping force. Also, the position of the lever relative to the clamping axis can be determined.

Clamping levers with eccentrical cam

Clamping levers with eccentrical cams, which use only threads to reduce or increase tension quickly without torque, are selflocking due to the tensiontolever ratio just before the clamping point. Available in plastic, zinc die cast and stainless steel, in inch or metric sizes.

A version with an adjustable bearing plate allows for the distance between the eccentrical cam and the contact surface to be 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.

Clamping levers are also known as cam levers and allow for the quick and easy adjusting and holding of parts during light machining or assembly without the use of tools.
