A gear rack mated with a pinion gear creates a linear actuator that converts rotational movement into linear motion or vice versa. The pinion, a circular equipment, engages one’s teeth on the rack, a straight, or “linear,” equipment. Rotational motion put on the pinion may cause the rack to go relative the pinion; conversely, linear motion applied to the rack will cause the pinion to go relative to the rack. In either situation, the input movement is translated into 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 for you personally.
Rack and pinion actuators give a rotational movement made to open and close quarter-change valves such as for example ball, butterfly, or plug valves and in addition for operating industrial or commercial dampers.
The rotational movement of a rack and pinion actuator is accomplished via linear movement and two gears. A circular gear, referred to a “pinion” engages the teeth of a linear gear “bar” known 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 motion is transferred to the rotary pinion gear (in both directions) offering bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with atmosphere, 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 surroundings, gas, or oil must be redirected to the additional 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 rely 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 and closed positions. Globe standard ISO installation pad are commonly available 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 an excellent life cycle. There are several brands of rack and pinion actuators in the marketplace, all with subtle variations in piston seals, shaft seals, spring style and body designs.

Rack-and-pinion pneumatic actuators, also called limited rotation cylinders, are rotary actuators used for turning, opening, closing, blending, oscillating, positioning, steering and many more mechanical features involving restricted rotation. These actuators are also frequently used for automation of quarter-change 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 needed by this actuator is provided via a central compressed atmosphere station, which usually supports a range of pneumatic devices in an activity system.
