A equipment 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 directly, or “linear,” equipment. Rotational motion applied to the pinion will cause the rack to go relative the pinion; conversely, linear motion 
put on the rack will cause the pinion to move in accordance with 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 easy to find the appropriate rack and pinion linear actuator to your requirements. Particular 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 and close quarter-convert valves such as ball, butterfly, or connect valves and also for operating commercial or commercial dampers.
The rotational movement of a rack and pinion actuator is accomplished via linear motion and two gears. A circular gear, referred to a “pinion” engages one’s teeth of a linear gear “bar” known as the “rack”.
Pneumatic actuators use pistons that are attached to the rack. As air flow or spring power is used the to pistons, the rack is usually “pushed” inward or “pulled” outward. This linear movement is transferred to the rotary pinion equipment (in both directions) providing bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with air, gas, or essential oil to provide the linear the motion that spins the pinion equipment. To rotate the pinion gear in the contrary direction, the air, gas, or oil should be redirected to the other sides of the piston, or make use of coil springs as the energy 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-level travel with clockwise and counterclockwise travel adjustment for open up and closed positions. Globe standard ISO mounting pad are commonly available to provide ease and versatility 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 plenty of brands of rack and pinion actuators in the marketplace, all with subtle distinctions in piston seals, shaft seals, spring design and body designs.
For almost twenty years we’ve used our engineering experience and industry encounter to continually improve our items, striving to supply robust solutions and competitive prices. Created for easy integration and reliability, our products have been proven in a variety of industries and applications including chemical, pharmaceutical, meals and beverage, power, oil and gas, wastewater, and dampers. We also strive to provide exceptional customer support to back our items and maintain your downtime to a minimum.
Our patented adjustable dual travel stops supply 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 add-ons including 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, combining, oscillating, positioning, steering and much more mechanical functions involving restricted rotation. These actuators are also frequently used for automation of quarter-turn valves, like ball or butterfly valves.
Pneumatic rack-and-pinion actuators convert the energy of Gear Rack For Rack Actuator compressed air by means of a pneumatic cylinder to an oscillating rotary motion. The clean, dried out, and processed gas required by this actuator is definitely provided with a central compressed air flow station, which usually supports a variety of pneumatic gadgets in an activity system.
