4X4

The Vahn-Tech Series 4X4 packs more than double the torque of conventional rack and pinion actuators thanks to its four pistons generating torque around a centrally located pinion. With more pistons in the actuator, this allows the actuator being more compact with size reduced by more than 30% compared to double piston actuator of the same torque. With four small cylinders each located on one of four sides of the unit and at a given air pressure, the 4×4 produces the same torque output as double piston models using smaller diameter pistons and a narrower pinion. The narrower pinion allows the pistons to travel shorter distances so that they can move faster from one position to the next.
