Page 666 | 2.3 Tensioning with Eccentric Cams and Wedge Clamps 1 l 1 2 d 1 4 Type How to order (Bushing steel) 1 2 3 GN926-79-M8-A 4 Type A With adjustable contact plate B With fixed contact plate Clamping levers with eccentrical cam GN 926 / GN 926.1 are used for rapid clamping and releasing. Hereby, contrary to a clamping operation via a thread, these levers permit a torque-free 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 moun- ted in their correct order. With these clamping levers with eccentrical cam GN 926 / GN 926.1, clamping forces of up to 4 kN (l 1 = 63) bzw. 7 kN (l 1 = 79) can be reached. Type A has the following benefits: The distance between the lever cams and the clamping surface is adjus- table via a planar curve, 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.
