After the spectacular re-launch of the SCHUNK PGN-plus parallel gripper, the competence leader for clamping technology and gripping systems has now rolled out the superior features of its flagship product for inclusion in the 3-finger gripper series. This way, the new SCHUNK PZN-plus centric gripper is equipped with a permanent lubrication in the multi-tooth guidance which, under normal, clean operating conditions, ensures lifelong maintenance-free operation. With short strokes in particular, the continuous lubricant pockets produce a particularly fast and even distribution of lubricant along the entire multi-tooth guide contour. By enlarging the supporting dimensions between the six loadbearing shoulders of the patented multi-tooth guidance, higher moments can be accommodated and thus longer fingers can be used. In order to ensure a perfect accuracy of fit, each individual base jaw was carefully manually ground and individually fitted to its casing. In addition, the large piston drive area produces maximum gripping force. Compared with conventional T-slotguided centric grippers, the new SCHUNK PZN-plus enables up to 50 percent longer gripper fingers, and a finger load up to 120 percent higher. Versatile screw-on options, matching those of the previous model, ensure complete compatibility and maximum flexibility with the process and system design.
