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 straight, or “linear,” gear. Rotational motion put on the pinion will cause the rack to go relative the pinion; conversely, linear motion put on the rack may cause the pinion to go relative to the rack. In either scenario, the input motion is translated in to the opposite output motion.

Available in five the latest models of of stroke lengths between 10mm and 30mm, it’s easy to find the appropriate rack and pinion linear actuator for your needs. Special stroke lengths and customized rack and pinion gearboxes could be supplied to meet your requirements.
Rack and pinion actuators give a rotational movement designed to open and close quarter-convert 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 equipment, described a “pinion” engages the teeth of a linear gear “bar” referred to as the “rack”.
Pneumatic actuators use Gear Rack For Rack Actuator pistons that are attached to the rack. As air flow 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) providing bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with air flow, gas, or oil to supply the linear the motion that spins the pinion equipment. 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 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 aspect pressurization of the rack are known as “direct acting”.
Most actuators are created for 100-level travel with clockwise and counterclockwise travel adjustment for open up and closed positions. World standard ISO installation pad are commonly available to provide relieve and flexibility in direct valve set up.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are reliable, durable and provide a good life routine. There are numerous brands of rack and pinion actuators out there, all with subtle variations in piston seals, shaft seals, spring style and body designs.
For almost twenty years we’ve used our engineering knowledge and industry experience to continually improve our products, striving to supply robust solutions and competitive prices. Created for easy integration and reliability, our products have already been proven in a variety of industries and applications including chemical, pharmaceutical, meals and beverage, power, coal and oil, wastewater, and dampers. We also strive to provide exceptional customer care to back our items and keep your downtime to the very least.
Our patented adjustable dual travel stops provide the greatest degree of control in the industry at ±10 degrees on each end of the stroke. To complement our actuators we have a complete range of control add-ons 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 much more mechanical functions involving restricted rotation. These actuators are also frequently used 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, dry, and processed gas necessary by this actuator is usually provided via a central compressed air flow station, which usually supports a variety of pneumatic gadgets in a process system.
