Information

The clamping principle of pneumatically operated clamps GN 860 is identical in construction and dimensions to the manually operated vertical clamps GN 810.

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 lubro control unit should be fitted in the air line.

Pneumatically operated clamps GN 860 are also available as from size 200 as a version M (magnetic piston). In conjunction with proximity switches GN 896.1 / GN 896.2 the piston position can be sensed and the generated impulse can be used to transmit an electrical signal. Further technical details see GN 896.1 / GN 896.2.
