Perfect for use in areas with high temperatures, contamination, and aggressive media, as well as for cleanrooms, the PGN-Plus-P universal gripper can accommodate longer fingers and greater loads. It has an enlarged drive piston area that increases grip force so that higher workpiece weights can be handled. The redesigned wedge drive mechanism provides lower friction and greater surface area that transmits more energy to the jaws, creating even more grip force.

SCHUNK, Inc. (Morrisville, NC) has introduced several improvements on the original PGN-Plus and has announced their newest generation gripper, PGN-Plus-P. Enlarged supporting dimensions between the six load-bearing shoulders of the multi-tooth guidance allow higher moment capacity which can accommodated longer fingers and greater loads. Permanent lubrication is provided through continuous lubrication pockets in the guidance. For short strokes in particular, the principle of minimum quantity lubrication ensures quick and even distribution of the lubricant making the gripper nearly maintenance-free and considerably extends its service life.

The PGN-plus-P also has an enlarged drive piston area which increases grip force so that higher workpiece weights can be handled. In addition to the larger piston, the wedge drive mechanism has been redesigned for lower friction and greater surface area which transmits more energy to the jaws creating even more grip force than previous generations. The PGN-plus-P is perfect for use in areas with high temperatures, contamination, and aggressive media, as well as for cleanrooms. On request, the module is available with spring safety, mechanical gripping force maintenance, compensation units for compensating angular misalignment, dust-proof versions, or as special high-precision versions. PGN-Plus-P continues to offer the most complete list of options in the industry including sensors, tool changers, finger blanks and dust protection. The PGN-Plus-P is available in sizes 50 to 125.
