QPGB

QPGB is a universal pneumatic self-centering 3-jaw gripper with through-hole, designed for applications requiring a central hole (e.g. workpiece feed, special sensor systems, or optical recognition systems).

Models

QPGB is a universal pneumatic self-centering 3-jaw gripper with through-hole, with high reliability and long service life, suitable for applications requiring a central hole (e.g. for workpiece feeding, special sensor systems, or optical recognition systems).

Advantages

  • Robust and lightweight housing made of hard-coated anodized aluminum alloy.
  • Sturdy T-slot with hardened steel gibs for effective jaw guidance, precise handling, and easy maintenance.
  • Central through-hole can be used for routing supply hoses and utility lines.
  • 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 of magnetic-field sensors.
  • Air supply via hose-free direct connections or fitting screw connections.
