GN890 Pneumatically Operated Push Pull Clamp Magnetic Piston
The working principle of these clamps, GN 890, is identical in construction and dimensions to the manual plunger clamp GN842.
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 protrude over the frame.
