Gripping modules

With the new SCHUNK PGN-plus-P, the major player for clamping technology and gripping systems is once again raising the bar with pneumatically powered universal grippers. The electric SCHUNK PGN-Plus-E applies the high-performance features of the pneumatic flagship directly in the area of mechatronic handling.
“Improving on proven technology” is SCHUNK’s motto for the development of the next generation of its mega-seller. Three technical innovations distinguish the newcomer SCHUNK PGN-plus-P. First, there is the improved multi-tooth guidance. By enlarging supporting dimensions between the six load-bearing shoulders of the patented multi-tooth guidance, higher moment can be accommodated and thus longer fingers can be used. In order to ensure a perfect fit, each individual base jaw undergoes elaborate manual grinding, and is individually adapted to the respective housing in the new gripper generation. Secondly, permanent lubrication is provided via the continuous lubrication pocket in the guidance. For short strokes in particular, the principle of minimum quantity lubrication particularly ensures quick and even distribution of the lubricant such that the gripper is nearly maintenance-free and its service life is extended. Finally, the SCHUNK PGN-plus-P has an enlarged drive piston area, whereby gripping force is increased and higher workpiece weights can be handled. In the first step, the new gripper benchmark is being introduced in sizes 50 to 125. Expansion to all existing PGN-plus unit sizes is planned.
