A gear rack mated with a pinion gear 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,” gear. Rotational motion put on the pinion may cause the rack to move relative the pinion; conversely, linear motion applied to the rack will cause the pinion to move relative to the rack. In either scenario, the input movement is translated into the opposite output motion.
Available in five different models of stroke lengths Gear Rack For Rack Actuator between 10mm and 30mm, it’s easy to find the right rack and pinion linear actuator for your needs. Unique stroke lengths and customized rack and pinion gearboxes can be supplied for you personally.
Rack and pinion actuators give a rotational movement designed to open and close quarter-turn valves such as for example ball, butterfly, or connect valves and in addition 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 gear, described a “pinion” engages the teeth of a linear gear “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As surroundings or springtime power is used the to pistons, the rack is “pushed” inward or “pulled” outward. This linear movement is transferred to the rotary pinion gear (in both directions) offering bi-directional rotation.
Rack and pinion actuators pistons could be pressurized with air, gas, or essential oil to supply the linear the movement 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 known 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-level 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 versatility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are reliable, durable and provide a good life routine. There are plenty of brands of rack and pinion actuators in the marketplace, all with subtle differences in piston seals, shaft seals, spring design and body designs.

Our patented adjustable dual travel stops supply the greatest amount 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 which includes 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, mixing, oscillating, positioning, steering and much more mechanical features involving restricted rotation. These actuators are also often used for automation of quarter-change 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, dried out, and processed gas necessary by this actuator is certainly provided via a central compressed air station, which often supports a variety of pneumatic products in an activity system.
