Pneumatic Parallel Grippers

QPGB 3-Finger

QPGB is a universal three-finger centric gripper, with a hollow center, featuring high reliability and a long service life, suitable for applications that require a center bore,(e.g. for workpiece feed, special sensor systems or optical recognition systems).

Advantages

  • Robust lightweight housing made of hard-coated aluminum alloy.
  • Sturdy T-slot with hardened steel gibs for effective jaw guidance, precise handling, and easy maintenance.
  • Central through-hole which can be used for feed through of supply hoses and utilities.
  • Mounting from one side in two screw directions for versatile and flexible integration.
  • Integrated permanent magnets for direct monitoring of piston movement.
  • Slots for mounting and positioning magnetic-field sensors.
  • Air supply via hose-free direct connections or fitting screw connections.
