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 one’s 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 applied to the rack will cause the pinion to go in accordance with the rack. In either circumstance, 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 easy to find the appropriate rack and pinion linear actuator for your needs. Special stroke lengths and custom rack and pinion gearboxes can be supplied to meet your requirements.
Rack and pinion actuators give a rotational movement made to open and close quarter-change valves such as ball, butterfly, or plug 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 gear, referred to a “pinion” engages one’s teeth of a linear equipment “bar” known as the “rack”.
Gear Rack For Rack Actuator Pneumatic actuators use pistons that are attached to the rack. As air or spring power is applied the to pistons, the rack is “pushed” inward or “pulled” outward. This linear motion is used in the rotary pinion gear (in both directions) providing bi-directional rotation.
Rack and pinion actuators pistons could be pressurized with surroundings, gas, or oil to provide the linear the movement that spins the pinion equipment. To rotate the pinion gear in the contrary direction, the atmosphere, 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 referred to as “spring-arrive back actuators”. Actuators that rely on opposite part 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. World standard ISO installation pad are commonly open to provide ease and versatility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are small and save space. They are reliable, durable and provide a good life cycle. There are many brands of rack and pinion actuators available, all with subtle differences in piston seals, shaft seals, spring design and body designs.

Our patented adjustable dual travel stops supply the greatest degree of control in the market at ±10 degrees on each end of the stroke. To complement our actuators we have a complete range of control add-ons including solenoid valves, limit switches, positioners, and a broad assortment of automation hardware.
Rack-and-pinion pneumatic actuators, also known as limited rotation cylinders, are rotary actuators used for turning, opening, closing, mixing, oscillating, positioning, steering and more mechanical functions involving restricted rotation. These actuators are also often used 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, dried out, and processed gas necessary by this actuator is certainly provided via a central compressed atmosphere station, which usually supports a range of pneumatic gadgets in a process system.
