GN 863 Heavy Duty Pneumatic Lock-Down Toggle Clamps Steel, with Magnetic Piston, with Vertical Mounting Base


Product description


GN 863 Heavy duty pneumatic lock-down 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 once it is dismantled, 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 mounted in the air in-feed line.

These clamps have a 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.
