Concentric Grippers produce 580-18,000 N grip force.
Press Release Summary:
Available in 5 body sizes from 64-60 mm, 3-finger Series PZN-plus offers stroke from 12-50 mm. Gripping positions of open, closed, or part present are monitored with magnetic or inductive switches. Forces and moments of gripper are spread over several surfaces of multiple-tooth guide. Moment loading capability is maximized, allowing high external loads to be applied without damage. For part loading against hard positions, spring packaged pressure plate is available.
Original Press Release:
New 3 Finger Gripper Delivers Higher Load Capacity And Longer Finger Capability
SCHUNK,Inc. has introduced a complete new series 3-finger concentric gripper - PZN-plus. Extending the capabilities of the current industry standard PZN series, the "Plus" stands for even higher load capacities, longer finger capability and better efficiency.
The basis for this increase in efficiency on the PZN-plus is the newly designed jaw guidance. Forces and moments of the gripper - or acting on the gripper - are spread over several surfaces of a multiple-tooth guide, enabling finger length increases of up to 30%. Moment loading capability is greatly enhanced allowing higher external loads to be applied without damage to the gripper or problems with operation. The actuation mechanism is based on the proven double wedge principal. The size of the wedge was increased compared to the standard PZN to assure absolute reliability even under the increased loads. The pneumatic cylinder is integrated directly in the housing providing the most compact lightweight package possible.
The gripper is available in 5 body sizes from 64mm to 60mm.Even with this small size, the grippers produce between 580N and 18,000N of grip force with strokes from 12 mm to 50 mm.Each body size has multiple stroke versions with I.D. or O.D. spring assist. These options assure proper sizing exactly to the application without compromise. The gripping conditions of open, closed or part present are easily monitored with magnetic or inductive type switches. Up to 5 positions can be monitored with the optional SCHUNK FPS. For part loading against hard positions, a spring packaged pressure plate is available.
