A equipment rack mated with a pinion equipment 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,” gear. Rotational motion applied to the pinion may cause the rack to go relative the pinion; conversely, linear motion put on the rack may cause the pinion to move relative to the rack. In either situation, the input motion 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. Unique stroke lengths and customized rack and pinion gearboxes can be supplied for you personally.
Rack and pinion actuators provide a rotational movement made to open and close quarter-convert valves such as ball, butterfly, or plug valves and also for operating industrial or commercial dampers.
The rotational movement of a rack and pinion actuator is accomplished via linear movement and two gears. A circular equipment, referred to a “pinion” engages the teeth of a linear gear “bar” known as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As surroundings or spring power is applied the to pistons, the rack is “pushed” inward or “pulled” outward. This linear movement is used in the rotary pinion equipment (in both directions) offering bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with air, gas, or oil to provide the linear the movement that spins the pinion equipment. To rotate the pinion equipment in the opposite direction, the air flow, gas, or oil should be redirected to the various other sides of the piston, or use coil springs as the energy source for rotation. Rack and pinion actuators using springs are referred to as “spring-return actuators”. Actuators that rely on opposite aspect pressurization of the rack are known as “direct acting”.
Most actuators are created for 100-degree travel with clockwise and counterclockwise travel adjustment for open up and closed positions. World standard ISO mounting pad are commonly open to provide ease and flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are dependable, durable and provide an excellent life cycle. There are several 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 known as limited rotation cylinders, are rotary actuators used for turning, opening, closing, combining, oscillating, positioning, steering and much more mechanical functions involving restricted rotation. These actuators are also often used for automation of quarter-turn valves, like ball or butterfly valves.
Pneumatic rack-and-pinion actuators convert the energy of compressed air through a pneumatic cylinder to an oscillating rotary motion. The clean, dry, and processed gas needed by this actuator can be provided via a central compressed air flow station, which often supports a variety of pneumatic devices in a process system.
