3 Parallel Gripper WG WGS-50 Parallel Gripper Gripper summary of Operation: Synchronous motion is achieved with a double acting piston attached via the piston shaft to a double sided wedge. The double sided angles of the wedge convert vertical motion to synchronous horizontal motion of the jaws. A. Body Hardcoat Anodized PTFE impregnated aluminum inside and out. Ultra high gripping force to weight ratio. B. Jaws Jaws machined from S7 tool steel to prevent jaw breakage. C. Switches Proximity switches are available to monitor open and closed position of the jaws. D. Side Ports Additional side mounting holes and side air ports for optional mounting and porting. E. Lubrication Pre-lubricated with our specially formulated oil based compound for extensive maintenance free performance.
