GN 890 Toggle clamps pneumatic, for push clamping, with magnetic piston


Product description


The working principle of the GN 890 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 cylinder, the operating pressure should not exceed 6 bar. In addition a lubrication control unit should be mounted in the air in-feed line. The sturdy mounting frame for the cylinder has been designed to avoid the trunions of the cylinder to protruding over the frame.

In conjunction with a proximity switch (GN 896.1 / GN 896.2) the end position is sensed and the generated signal can be used in sequence control systems.
