Rotary actuators offer high performance
The Cylinder Division of Parker Hannifin has launched its latest range of HTR rack and pinion rotary actuators. The latest HTR actuators are designed to improve the performance and operational flexibility of a wide variety of loading and handling systems in the factory automation, process, construction and marine sectors.
The robust HTR actuators use proven tie rod cylinder technology, with cylinder pistons mounted on each end of a hardened steel toothed rack which engages with a rotary pinion shaft set at 90 degrees to the direction of piston stroke. The complete unit is durable, with a housing manufactured from hardened alloy steel. Just as importantly, all mechanical components are completely enclosed, making it safe to use and free of potential pinch points.
The standard range of HTR actuators can be supplied with pinion shafts capable of rotating through 90deg, 180deg and 360deg angles, while custom versions are available for any range of movement up to five full revolutions. All models deliver uniform torque in both directions, ensuring high levels of motion control and performance. Simple yet robust, the rack can be pre-loaded to eliminate the effects of backlash.
