About Grippers

Grippers activate jaws or fingers to pick up, hold, or move work pieces in an automated or robotic system. The gripping elements can be angular or fingers that pivot about base points or jaws that slide parallel or in the same plane with each other like clamps or chuck jaws. They may be actuated manually, electrically, pneumatically, or hydraulically.  Manual grippers are actuated by hand crank, wheel, levers, or other manual or mechanical means.  Electric grippers fingers or jaws are actuated by electric motor, solenoid, etc.  Pneumatic grippers are actuated by compressed air acting on a cylinder or vanes.  Hydraulic grippers are actuated by hydraulic fluid acting on a cylinder or vanes.  Many configurations and numbers of gripping elements are available.

The number of grips on grippers generally range from one to six, but greater numbers are available.  Gripper action can be single action, double action, double action spring assist open, or double action spring assist close.  Single action grippers contain drive in only one direction. Single action grippers frequently incorporate a return spring to the unpowered position (supply pressure or electricity off.  Double action grippers are actuated both open and closed. Force ratings can differ in the two directions.  Double action spring assist open grippers have an actuation method that opens and closes the gripper, but with spring assist in open direction (spring opposes closing).  Double action spring assist close grippers have an actuation method that opens and closes the gripper, but with spring assist in the close direction (spring opposes opening).
