Information

Toggle clamps GN 861 have been constructed in such a way as to make them easy to unmount. The bearing bolts 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 cylinders, the operating pressure should not exceed 6 bar and a compressed air maintenance unit should be installed upstream.

Toggle clamps GN 861 have a magnetic piston. In conjunction with sensors GN 3380, the end position can be sensed and the generated impulse can be used to transmit an electrical signal.
