A gear rack mated with a pinion equipment 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,” gear. Rotational motion applied to the pinion will cause the rack to move relative the pinion; conversely, linear motion put on the rack will cause the pinion to move in accordance with the rack. In either scenario, the input movement is translated into 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. Unique stroke lengths and custom rack and pinion gearboxes could be supplied for you personally.
Rack and pinion actuators provide a rotational movement made to open up and close quarter-change valves such as for example ball, butterfly, or connect valves and in addition 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 equipment, referred to a “pinion” engages the teeth of a linear equipment “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are 
mounted on the rack. As air flow or spring power is used the to pistons, the rack can be “pushed” inward or “pulled” outward. This linear motion is transferred to the rotary pinion equipment (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 gear. To rotate the pinion gear in the contrary direction, the air, gas, or oil must 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 known as “spring-return actuators”. Actuators that depend on opposite side pressurization of the rack are referred to 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 installation pad are commonly open to provide relieve and versatility in direct valve set up.
Pneumatic pneumatic rack and pinion actuators are small and save space. They are reliable, durable and provide a good life cycle. There are various brands of rack and pinion actuators available, all with subtle distinctions in piston seals, shaft seals, spring style and body designs.

Our patented adjustable dual travel stops provide the greatest amount of control in the market at ±10 degrees upon each end of the stroke. To check our actuators we’ve a complete range of control components which includes solenoid valves, limit switches, positioners, and a broad assortment 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 more mechanical functions involving restricted rotation. These actuators are also often used for automation of quarter-change 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, dry, and processed gas required by this actuator is provided with a central compressed air station, which often supports a variety of pneumatic products in a process system.
