Information

The working principle of the GN 890 pneumatic toggle clamps is identical in construction and dimensions to the manual toggle clamps GN 842. To ensure an extended life of the mechanical parts as well as the air cylinders the operating pressure should not exceed 6 bar.
In addition a lubrication control unit should be fitted in the air line. The sturdy mounting frame for the cylinder has been designed to avoid the trunions of the cylinder to protrude over the frame.
GN 890 pneumatic toggle clamps are also available in sizes 360 and up as a version M (magnetic piston). In conjunction with GN 896.1 / GN 896.2 proximity switches, the piston position can be sensed and the generated impulse can be used to transmit an electrical signal.
