Properties and application:

  • In order to pass the dead centre point and / or compensate for work piece tolerances when using hand operated toggle clamps, an elastic thrust pad such as GN 708.1 can be used
  • Toggle clamp spindle assemblies GN 804 fitted with Belleville spring washers do not only help to overcome workpiece tolerances, but they also allow presetting of the required clamping force
  • This adjustment can be made with the hexagon nut (A/F)
  • The setting nut stroke is the distance by which the Belleville washers can be preloaded as shown on the above graph to give the required clamping force
  • Furthermore the thrust pad is movable
  • Hexagon nuts are included
  • Elesa+Ganter - technical information
