A gear rack mated with a pinion equipment creates a linear actuator that converts rotational motion into linear movement or vice versa. The pinion, a circular equipment, engages one’s teeth on the rack, a straight, or “linear,” equipment. Rotational motion applied to the pinion may cause the rack to move relative the pinion; conversely, linear motion applied to the rack will cause the pinion to move in accordance with 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 easy to find the right rack and pinion linear actuator for your needs. Special stroke lengths and custom rack and pinion gearboxes could be supplied to meet your requirements.
Rack and pinion Gear Rack For Window Opener Actuators give a rotational movement designed to open and close quarter-change valves such as ball, butterfly, or connect valves and also for operating commercial or commercial dampers.
The rotational motion of a rack and pinion actuator is accomplished via linear movement and two gears. A circular gear, described 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 air flow or spring power is applied the to pistons, the rack is certainly “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 can be pressurized with air flow, gas, or oil to provide the linear the motion that spins the pinion gear. To rotate the pinion gear in the opposite direction, the atmosphere, gas, or oil should be redirected to the 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-return actuators”. Actuators that rely on opposite side pressurization of the rack are known as “direct acting”.
Most actuators are made for 100-level travel with clockwise and counterclockwise travel adjustment for open and closed positions. World standard ISO mounting pad are commonly open to provide ease and flexibility in direct valve set up.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are reliable, durable and provide an excellent life routine. There are various brands of rack and pinion actuators out there, all with subtle distinctions in piston seals, shaft seals, spring style and body designs.

To check our actuators we’ve a complete selection of control accessories which includes solenoid valves, limit switches, positioners, and a wide assortment of automation hardware.
Rack-and-pinion pneumatic actuators, also known as limited rotation cylinders, are rotary actuators used for turning, opening, closing, combining, oscillating, positioning, steering and more mechanical functions involving restricted rotation. These actuators are also frequently used for automation of quarter-switch 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, dried out, and processed gas required by this actuator is definitely provided via a central compressed surroundings station, which often supports a variety of pneumatic gadgets in a process system.
