A equipment rack mated with a pinion gear creates a linear actuator that converts rotational movement into linear motion or vice versa. The pinion, a circular equipment, engages the teeth on the rack, a directly, or “linear,” gear. Rotational motion applied to the pinion will cause the rack to go relative the pinion; Gear Rack For Window Opener conversely, linear motion applied to the rack may 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 simple to find the right rack and pinion linear actuator for your needs. Unique stroke lengths and custom rack and pinion gearboxes can be supplied to meet your requirements.
Rack and pinion actuators provide a rotational movement designed to open up and close quarter-change valves such as for example 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 gear, described 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 flow or spring power is used the to pistons, the rack can be “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 surroundings, gas, or oil to provide the linear the movement that spins the pinion gear. To rotate the pinion gear in the opposite direction, the atmosphere, gas, or oil must be redirected to the additional sides of the piston, or use coil springs as the power source for rotation. Rack and pinion actuators using springs are known as “spring-return actuators”. Actuators that rely on opposite aspect 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 and closed positions. Globe standard ISO installation pad are commonly open to provide ease and flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are small and save space. They are reliable, durable and provide a good life routine. There are numerous brands of rack and pinion actuators on the market, all with subtle distinctions in piston seals, shaft seals, spring style and body designs.

Our patented adjustable dual travel stops supply the greatest amount of control in the market at ±10 degrees upon each end of 
the stroke. To check our actuators we’ve a complete selection of control accessories which includes solenoid valves, limit switches, positioners, and a broad range of automation hardware.
Rack-and-pinion pneumatic actuators, also called limited rotation cylinders, are rotary actuators used for turning, opening, closing, blending, oscillating, positioning, steering and many 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 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 air station, which usually supports a variety of pneumatic gadgets in a process system.
