A gear rack mated with a pinion gear creates a linear actuator that converts rotational movement into linear movement or vice versa. The pinion, a circular gear, engages one’s teeth on the rack, a straight, or “linear,” equipment. Rotational motion applied to the pinion may cause the rack to go relative the pinion; conversely, linear motion applied to the rack will cause the pinion to move in accordance with the rack. In either scenario, the input movement is translated in to the opposite output motion.
Available in five different models of stroke lengths between 10mm and 30mm, it’s easy to find the right rack and pinion linear actuator for your needs. Particular stroke lengths and customized rack and pinion gearboxes could be supplied for you personally.
Rack and pinion actuators give a rotational movement designed to open up and close quarter-convert valves such as for example ball, butterfly, or plug valves and also for operating commercial or commercial dampers.
The rotational movement of a rack and pinion actuator is accomplished via linear motion and two gears. A circular gear, referred to a “pinion” engages the teeth of a linear equipment “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As air flow or spring power is used the to pistons, the rack is certainly “pushed” inward or “pulled” outward. This linear movement is transferred to the rotary pinion gear (in both directions) providing bi-directional rotation.
Rack and pinion actuators pistons could be pressurized with atmosphere, gas, or oil to provide the linear the movement that spins the pinion gear. To rotate the pinion gear in the opposite direction, the surroundings, gas, or oil should be redirected to the other sides of the piston, or make use of coil springs as the power source for rotation. Rack and pinion actuators using springs are known as “spring-come back actuators”. Actuators that rely on opposite side pressurization of the rack are referred to as “direct acting”.
Most actuators are created for 100-level travel with clockwise and counterclockwise travel adjustment for open up and closed positions. World standard ISO mounting pad are commonly available to provide relieve and flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are reliable, durable and provide a good life cycle. There are plenty of brands of rack and pinion actuators available, all with subtle variations in piston seals, shaft seals, spring style and body designs.

Rack-and-pinion pneumatic actuators, also called limited rotation cylinders, are rotary actuators used for turning, opening, closing, blending, oscillating, positioning, steering and more mechanical features involving restricted rotation. These actuators are also often used for automation of quarter-change valves, like ball or butterfly valves.
Pneumatic rack-and-pinion actuators convert the energy of compressed air by means of a pneumatic cylinder to an oscillating rotary motion. The clean, dry, and processed gas necessary by this actuator is provided via a central compressed atmosphere station, which usually supports a variety of pneumatic products in a process system.
