The Numatics Series WG is a line of parallel grippers that achieve synchronous motion 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. The grippers can be slightly pressurized via the purge port to prevent debris or coolant from entering. Vacuum can also be applied to the purge port for use in a clean room environment.
