A gear rack mated with a pinion equipment creates a linear actuator that converts rotational motion into linear motion or vice versa. The pinion, a circular gear, engages the teeth on the rack, a directly, or “linear,” equipment. 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 move relative to the rack. In either circumstance, 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 for your needs. Particular stroke lengths and customized rack and pinion gearboxes could be supplied for you personally.
Rack and pinion actuators provide a rotational movement designed to open up and close quarter-switch valves such as for example ball, butterfly, or plug valves and also for operating commercial or commercial dampers.
The rotational motion of a rack and pinion actuator is accomplished via linear movement and two gears. A circular equipment, referred to a “pinion” engages the teeth of a linear equipment “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 flow, gas, or oil to supply the linear the movement that spins the pinion equipment. To rotate the pinion gear in the contrary 
direction, the atmosphere, gas, or oil should 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 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-degree 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 flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are dependable, durable and provide an excellent life routine. There are numerous brands of rack and pinion actuators out there, all with subtle distinctions in piston seals, shaft seals, spring design and body designs.

Our patented adjustable dual travel stops provide the greatest degree of control in the market at ±10 degrees upon each end of the stroke. To check our actuators we’ve a complete selection of control add-ons including 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 Gear Rack For Rack Actuator mechanical features involving restricted rotation. These actuators are also frequently utilized for automation of quarter-turn 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 definitely provided via a central compressed air flow station, which usually supports a range of pneumatic products in an activity system.
