A gear rack mated with a pinion gear creates a linear actuator that converts rotational Gear Rack For Rack Actuator movement into linear movement or vice versa. The pinion, a circular gear, engages the teeth on the rack, a straight, or “linear,” equipment. Rotational motion applied to the pinion may cause the rack to go relative the pinion; conversely, linear motion applied to the rack will cause the pinion to move relative to the rack. In either situation, 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 appropriate rack and pinion linear actuator to your requirements. Unique stroke lengths and customized rack and pinion gearboxes could be supplied to meet your requirements.
Rack and pinion actuators give a rotational movement made to open up and close quarter-switch valves such as for example ball, butterfly, or connect valves and also 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, described a “pinion” engages the teeth of a linear equipment “bar” known as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As air or springtime power is used the to pistons, the rack is definitely “pushed” inward or “pulled” outward. This linear motion 
is transferred to the rotary pinion gear (in both directions) providing bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with air flow, gas, or oil to provide the linear the motion that spins the pinion gear. To rotate the pinion equipment in the contrary direction, the atmosphere, gas, or oil must be redirected to the various other sides of the piston, or use coil springs as the energy source for rotation. Rack and pinion actuators using springs are referred to as “spring-come back actuators”. Actuators that rely on opposite part pressurization of the rack are known as “direct acting”.
Most actuators are made for 100-degree travel with clockwise and counterclockwise travel adjustment for open and closed positions. Globe standard ISO installation pad are commonly open 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 many brands of rack and pinion actuators on the market, all with subtle differences in piston seals, shaft seals, spring design and body designs.

To complement our actuators we have a complete range of control components which includes solenoid valves, limit switches, positioners, and a wide range 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 frequently utilized 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 necessary by this actuator can be provided with a central compressed air station, which usually supports a range of pneumatic devices in a process system.
