A equipment rack mated with a pinion equipment creates a linear actuator that converts rotational motion into linear motion 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 may cause the rack to move relative the pinion; conversely, linear motion applied to the rack may cause the pinion to go in accordance with the rack. In either scenario, the input movement is translated in to the opposite output motion.
Available in five the latest models of of stroke lengths between 10mm and 30mm, it’s simple to find the right rack and pinion linear actuator to your requirements. Particular stroke lengths and customized 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 Gear Rack For Rack Actuator 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 motion and two gears. A circular gear, described a “pinion” engages the teeth of a linear gear “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As surroundings or spring power is used the to pistons, the rack can be “pushed” inward or “pulled” outward. This linear movement is used in the rotary pinion gear (in both directions) offering bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with atmosphere, gas, or oil to provide the linear the movement that spins the pinion equipment. To rotate the pinion gear in the contrary direction, the air flow, gas, or oil should be redirected to the various other sides of the piston, or make use of coil springs as the power source for rotation. Rack and pinion actuators using springs are referred to as “spring-return actuators”. Actuators that depend on opposite part pressurization of the rack are known as “direct acting”.
Most actuators are designed for 100-degree 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 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 cycle. There are several brands of rack and pinion actuators on the market, all with subtle differences in piston seals, shaft seals, spring design and body designs.
For almost twenty years we have used our engineering expertise and industry encounter 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 variety of industries and applications which includes chemical, pharmaceutical, meals and beverage, power, oil and gas, wastewater, 
and dampers. We also strive to provide exceptional customer care to back our products and keep your downtime to the very least.
Our patented adjustable dual travel stops supply the greatest degree of control in the industry at ±10 degrees on each end of the stroke. To complement our actuators we’ve a complete selection of control accessories which includes solenoid valves, limit switches, positioners, and a wide range of automation hardware.
Rack-and-pinion pneumatic actuators, also called 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 often 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, dried out, and processed gas needed by this actuator can be provided via a central compressed atmosphere station, which often supports a variety of pneumatic gadgets in a process system.
