Właściwości i zastosowanie:

  • The working principle of the pneumatically operated plunger clamp GN 890 is identical in construction and dimensions to the manual plunger clamp GN 842
  • 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
  • The sturdy mounting frame for the cylinder has been designed to avoid the trunions of the cylinder to protrude over the frame
  • Pneumatically operated plunger clamps GN 890 are also available as from size 360 as version M (magnetic piston)
  • In conjunction with a proximity switch( GN 896.1/ GN 896.2) the position of the piston is sensed and the generated signal can be used in sequence control systems
  • Type SP3: body, steel forged
  • Code M: magnetic piston from size 360 upwards (only for versin with magnetic piston)
  • Elesa+Ganter toggle clamps - operating principle
