A equipment rack mated with a pinion equipment creates a linear actuator that converts rotational movement into linear motion or vice versa. The pinion, a circular gear, engages one’s teeth on the rack, a directly, or “linear,” gear. Rotational motion put on the pinion will cause the rack to go relative the pinion; conversely, linear motion put on the rack will cause the pinion to go in accordance with the rack. In either scenario, 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 right rack and pinion linear actuator to your requirements. Special stroke lengths and custom rack and pinion gearboxes can be supplied to meet your requirements.
Rack and pinion Gear Rack For Window Opener Actuators provide a rotational movement designed to open up and close quarter-convert valves such as ball, butterfly, or plug valves and in addition 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 equipment, referred to a “pinion” engages one’s teeth of a linear gear “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are attached to the rack. As atmosphere or spring power is used the to pistons, the rack is usually “pushed” inward or “pulled” outward. This linear motion is used in the rotary pinion equipment (in both directions) offering bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with air flow, gas, or essential oil to supply the linear the motion that spins the pinion gear. To rotate the pinion gear in the contrary direction, the atmosphere, gas, or oil must be redirected to the additional sides of the piston, or make use of coil springs as the power source for rotation. Rack and pinion actuators using springs are known as “spring-return actuators”. Actuators that rely on opposite side pressurization of the rack are referred to as “direct acting”.
Most actuators are created for 100-degree travel with clockwise and counterclockwise travel adjustment for open and closed positions. World standard ISO installation pad are commonly available to provide ease and flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are reliable, durable and provide an excellent life cycle. There are plenty of brands of rack and pinion actuators available, all with subtle variations in piston seals, shaft seals, spring design and body designs.

To check our actuators we’ve a complete selection of control add-ons which includes 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 features involving restricted rotation. These actuators are also frequently used for automation of quarter-switch 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, dry, and processed gas needed by this actuator is definitely provided via a central compressed air flow station, which usually supports a variety of pneumatic gadgets in an activity system.
