Family Products RP-012-022-046-090-170-270-350-550
This is the medium-size Rack and Pinion series for torques up to 550.000 Nm. Its design is very flexible, there can be many possible configurations thanks to the modular components and to the design specifically studied to satisfy different dimensional and torque needs.
The interface is developed and optimized to allow the interchange of cylinders and spring packs of the corresponding scotch yoke actuators. By doing so, productivity is optimized and it is possible to reduce costs and delivery time.
The pneumatic version employs tandem and triple cylinders up to a diameter of 935 mm in order to ensure a great dimensional versatility and a wide range of pressure to be used.
