Gripper Swivel Units

There are three base swivel unit sizes and each can be equipped with one of four different gripper types.

They offer a range of grippers: two-finger parallel, three-finger concentric, two-finger angular, and 180° angular. With hydraulic shock absorbers to dampen rotation, GSM is fully adjustable from 0 to 180°. The gripper swivel incorporates a hose-free connection for air supply and magnetic sensors in the body for position feedback on both the gripper and swivel units. There are a total of 92 different versions with strokes ranging from 4 to 20 mm and a grip-force range of 28 (6.3 lbf) to 270 N (61 lbf).
