Gramforce gripper

The GramForce™ gripper from Airpot is a synchronous, parallel, piston-actuated gripper specifically designed for applications requiring low forces and high accuracy. This gripper utilizes two ultra-low friction actuators with a 5.6 mm bore and Airpel® Plus technology, resulting in minimal friction and consistent gripping forces from 0.25 N to 8.6 N. The gripper is pre-lubricated for life and requires no maintenance. With a compact design and a total weight of 205 grams, this gripper is ideal for precision assembly, test and measurement equipment, robotic arms, and handling small, delicate components.

Advantages

  • Ultra-low friction due to Airpel® Plus technology for accurate force transmission
  • Wide pressure range (0.02–0.7 MPa) for adapting to various applications
  • Compact and lightweight (205 g) for integration in space-constrained environments
  • Maintenance-free due to lifetime pre-lubrication
  • Synchronous and parallel movement for consistent gripping force in any mounting orientation
  • Suitable for delicate components thanks to low minimum gripping force (0.25 N)
  • Flexible finger mounting for custom solutions
