Pick-and-Place Grippers
Combine these grippers with your gripping fingers to lift and move items in pick-and-place applications.
Grippers with a spring jaw return have a single air port to close the jaws and grip items from the outside. An internal spring opens the jaws to release the grip.
Grippers with a forced-air jaw return have two air ports: one to move the jaws open and another to move them closed. The jaws grip items from the outside as well as the inside.
Angular grippers allow a more secure grip on irregularly shaped loads.
Note: Choose a gripper with a holding force at least 10 times your item's weight.
Warning: Never use to lift people or items over people.

Rotary Pick-and-Place Grippers
These grippers pick up a product and turn it 90° or 180° before releasing. Use them with gripping fingers to lift and move items in pick-and-place applications. They have two air ports: one to move the jaws open and another to move them closed. The jaws can grip items from the outside as well as the inside.
Warning: Never use to lift people or items over people.

Electric-Powered Grippers without Motor
For applications without access to compressed air, such as mobile robots, these grippers use electricity to perform highly accurate pick and place tasks including assembly, finishing, and packaging. Compared to air-powered grippers, which leak air, these grippers don’t release dirt or particulates, so they’re better for electronic component production lines, laboratories, and other clean environments. They grip parts from the inside or outside because they open and close with equal force. To connect gripper fingers (not included) and to make sure the fingers don’t shift, these grippers have three mounting connections for each finger. If there’s a power loss, they maintain their hold, preventing harm to parts and nearby people.
Choose a gripper that matches the type of motor you want to connect and your motor’s frame size. All include mounting hardware to secure them to your motor.
Warning: Never use to lift people or items over people.
