Pneumatic O-Ring Grippers

OPR – PM 6-Finger

OPR and PM are innovative multi-finger grippers for handling and assembling O-rings

Advantages

  • They are specifically designed with an independent device which expands the gasket and another which subsequently ejects it for assembling.
  • Ability to assemble particularly thick gaskets and to position them in seats which are located at a distance from the ends of the housing.
  • Adjustable stroke suitable for different O-ring sizes.
  • Robust lightweight housing made of hard-coated aluminum alloy.
  • OPR50 includes specially designed fingers.
