Properties and application:
- Pneumatically operated clamps GN 863 have been constructed in such a way as to make them easily demountable: 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 air cylinder 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 863 are also available as version M (magnetic piston)
- In conjunction with a proximity switch GN 896.3 the piston position is sensed and the generated signal can be used in sequence control systems
- Type EPV: solid clamping arm
- Code M: magnetic piston
- Elesa+Ganter toggle clamps - operating principle
