GN 861 heavy duty pneumatic toggle clamps have been constructed in such a way as to make them easy to unmount. The bearing pins are axially fixed with circlips. This allows the clamping arm to be modified to suit any particular application.

To ensure an extended life of the mechanical parts as well as the air cylinder the operating pressure should not exceed 6 bar. In addition a lubrication control unit should be fitted in the air line.

GN 861 pneumatic toggle clamps are available as version M (magnetic piston). In conjunction with a GN 896.3- proximity switch the piston position is sensed and the generated signal can be used in sequence control systems.
