Information
In order to pass the dead center point and/or compensate for work piece tolerances when using hand operated toggle clamps, a spring-loaded thrust pad such as GN 804 can be used.
Gn 804 toggle clamp spindle assemblies, which inlude Belleville spring washers, not only help to overcome workpiece tolerances, but also allow presetting of the required clamping force.
This adjustment can be made with the hex nut (A/F). The setting nut stroke is the distance by which the diaphragm springs can be preloaded as shown on the above graph to give the required clamping force.
Hex jam nuts are included.
