Properties and application:

  • Pneumatically operated clamps GN 861 have been constructed in such a way as to make them easily demountable
  • The bearing pins are axially fixed with circlips
  • This allows the clamping arm to be modified to suit any particular application
  • 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 lubro control unit should be fitted in the air line
  • Pneumatically operated clamps GN 861 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 EP: solid clamping arm
  • Coding M: Magnetic piston
  • Elesa+Ganter toggle clamps - operating principle
