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 the teeth on the rack, a directly, or “linear,” equipment. 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 in accordance with the rack. In either circumstance, 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. Particular stroke lengths and customized rack and pinion gearboxes can be supplied to meet your requirements.
Rack and pinion actuators give a rotational movement made to open up and close quarter-convert valves such as for example ball, butterfly, or connect valves and also for operating industrial or commercial dampers.
The rotational motion of a rack and pinion actuator is accomplished via linear movement and two gears. A circular gear, referred to a “pinion” engages one’s teeth of a linear gear “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As atmosphere or springtime power is used the to pistons, the rack is “pushed” inward or “pulled” outward. This linear motion is used in the rotary pinion equipment (in both directions) offering bi-directional rotation.
Rack and pinion actuators pistons could be pressurized with air flow, gas, or essential oil to provide the linear the movement that spins the pinion equipment. To rotate the pinion equipment in the opposite direction, the air, gas, or oil must be redirected to the 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-arrive back actuators”. Actuators that rely on opposite part pressurization of the rack are known as “direct acting”.
Most actuators are made for 100-degree travel with clockwise and counterclockwise travel adjustment for open and closed positions. World standard ISO mounting pad are commonly open to provide relieve and versatility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are reliable, durable and provide an excellent life cycle. There are numerous brands of rack and pinion actuators in the marketplace, all with subtle distinctions in piston seals, shaft seals, spring design and body designs.

Rack-and-pinion pneumatic actuators, also called limited rotation cylinders, are rotary actuators used for turning, opening, closing, mixing, oscillating, positioning, steering and more mechanical features involving restricted rotation. These actuators are also often utilized for automation of quarter-convert 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 can be provided with a central compressed air flow station, which usually supports a variety of pneumatic devices in a process system.
