A gear rack mated with a pinion equipment creates a linear actuator that converts rotational motion into linear motion or vice versa. The pinion, a circular equipment, engages one’s teeth on the rack, a straight, or “linear,” equipment. Rotational motion put on the pinion will cause the rack to move relative the pinion; conversely, linear motion put on the rack may cause the pinion to move relative to the rack. In either circumstance, the input motion is translated into the opposite output motion.
Available in five the latest models of of stroke lengths between 10mm and 30mm, it’s easy to find the right rack and pinion linear actuator to your requirements. Particular stroke lengths and customized rack and pinion gearboxes can be supplied to meet your requirements.
Rack and pinion actuators provide a rotational movement designed to open and close quarter-turn valves such as for example ball, butterfly, or plug valves and in addition for operating industrial or commercial dampers.
The rotational motion 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 applied the to pistons, the rack is definitely “pushed” inward or “pulled” outward. This linear movement is transferred to the rotary pinion gear (in both directions) offering bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with air flow, gas, or oil to supply the linear the movement that spins the pinion equipment. To rotate the pinion equipment in the opposite direction, the surroundings, gas, or oil must be redirected to the various other sides of the piston, or use coil springs as the power source for rotation. Rack and pinion actuators using springs are referred to as “spring-come back actuators”. Actuators that rely on opposite part pressurization of the rack are referred to as “direct acting”.
Most actuators are made for 100-degree travel with clockwise and counterclockwise travel adjustment for open up and closed positions. Globe standard ISO installation pad are commonly available to provide ease and flexibility in direct valve set up.
Pneumatic pneumatic rack and pinion actuators are small and save space. They are reliable, durable and provide a good life cycle. There are various brands of rack and pinion actuators available, all with subtle differences 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 utilized for automation of quarter-turn 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 range of pneumatic gadgets in an activity system.
