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 equipment, engages one’s teeth on the rack, a directly, or “linear,” gear. Rotational motion put on the pinion will cause the rack to go relative the pinion; conversely, linear motion applied to the rack will cause the pinion to move relative to the rack. In either situation, the input motion is translated into the opposite output motion.
Available in five different models of stroke lengths between 10mm and 30mm, it’s simple to find the appropriate rack and pinion linear actuator for your needs. Particular stroke lengths and custom rack and pinion gearboxes could be supplied for you personally.
Rack and pinion actuators provide a rotational movement made to open up and close quarter-switch valves such as for example ball, butterfly, or plug valves and also 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 one’s teeth of a linear equipment “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As air or spring power is used the to pistons, the rack is definitely “pushed” inward or “pulled” outward. This linear movement is used in the rotary pinion gear (in both directions) providing bi-directional rotation.
Rack and pinion actuators pistons could be pressurized with surroundings, gas, or oil to supply the linear the movement that spins the pinion gear. To rotate the pinion equipment in the opposite direction, the air, gas, or oil should be redirected to the other sides of the piston, or make use of 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 part pressurization of the rack are referred to as “direct acting”.
Most actuators are made for 100-level travel with clockwise and counterclockwise travel adjustment for open and closed positions. Globe standard ISO mounting pad are Gear Rack For Window Opener commonly open to provide relieve and flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are small and save space. They are reliable, durable and provide an excellent life cycle. There are several brands of rack and pinion actuators in the marketplace, all with subtle distinctions in piston seals, shaft seals, spring design and body designs.

Our patented adjustable dual travel stops supply the greatest amount of control in the market at ±10 degrees on each end of the stroke. To check our actuators we have a complete range of control components which includes solenoid valves, limit switches, positioners, and a wide range of automation hardware.
Rack-and-pinion pneumatic actuators, also known as limited rotation cylinders, are rotary actuators used for turning, opening, closing, mixing, oscillating, positioning, steering and many more mechanical features involving restricted rotation. These actuators are also frequently 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, dried out, and processed gas needed by this actuator is provided via a central compressed air flow station, which usually supports a variety of pneumatic gadgets in an activity system.
