According to the movement mode, the gripper can be divided into parallel opening and closing type and fulcrum opening and closing type.

The selection of air jaws mainly considers clamping force, finger bending moment, etc.

Let's take parallel opening and closing air grippers as an example to describe how to choose the right air gripper.

The clamping point distance refers to the distance from the center of the workpiece (including fingers) from the mounting surface of the slider, and the effective clamping force refers to the thrust of each claw.

Under normal circumstances, the clamping force can take 10~20 times of the weight of the workpiece, according to the grasping method and workpiece size to determine the clamping point distance, with the increase of the clamping point distance, the clamping capacity is decreasing.
