A gear rack mated with a pinion gear creates a linear actuator that converts rotational motion into linear movement or vice versa. The pinion, a circular equipment, engages the teeth on the rack, a straight, or “linear,” equipment. Rotational motion applied to 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 in to 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 customized rack and pinion gearboxes could be supplied to meet your requirements.
Rack and pinion actuators give a rotational movement made to open up and close quarter-switch valves such as 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 motion and two gears. A circular gear, described a “pinion” engages the teeth of a linear equipment “bar” known as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As surroundings or springtime power is applied the to pistons, the rack is “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 could be pressurized with surroundings, gas, or oil to provide the linear the motion that spins the pinion equipment. To rotate the pinion equipment in the opposite direction, the air flow, gas, or oil must be redirected to the other sides of the piston, or make use of coil springs as the power source for rotation. Rack and pinion actuators using springs are known as “spring-come back actuators”. Actuators that rely on opposite side pressurization of the rack are referred to as “direct acting”.
Most actuators are designed for 100-level travel with clockwise and counterclockwise travel adjustment for open up and closed positions. Globe 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 dependable, durable and provide a good life routine. There are several brands of rack and pinion actuators in the marketplace, all with subtle differences in piston seals, shaft seals, spring style and body designs.
For almost 20 years we have used our engineering knowledge and industry experience to continually improve our products, striving to provide robust solutions and competitive prices. Designed for easy integration and reliability, our products have already been proven in a number of industries and applications including chemical, pharmaceutical, meals and beverage, power, coal and oil, wastewater, and dampers.

Our patented adjustable dual travel stops provide the greatest degree of control in the industry at ±10 degrees upon each end of the stroke. To complement our actuators we have 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 known as limited rotation cylinders, are rotary actuators used for turning, opening, closing, blending, oscillating, positioning, steering and many more mechanical Gear Rack For Window Opener features involving restricted rotation. These actuators are also frequently utilized for automation of quarter-turn 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 needed by this actuator can be provided via a central compressed air flow station, which usually supports a variety of pneumatic gadgets in an activity system.
