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 the teeth on the rack, a directly, or “linear,” equipment. Rotational motion put on the pinion may cause the rack to move relative the pinion; conversely, linear motion applied to the rack may cause the pinion to go in accordance with the rack. In either situation, the input motion is translated in to 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 can be supplied for you personally.
Rack and pinion actuators give a rotational movement made to open 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 gear, described a “pinion” engages one’s teeth of a linear equipment “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 is usually “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 oil to provide the linear the motion that spins the pinion equipment. To rotate the pinion gear in the opposite direction, the surroundings, gas, or oil must be redirected to the additional 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 rely on opposite aspect pressurization of the rack are referred to as “direct acting”.
Most actuators are made for 100-level travel with clockwise and counterclockwise travel adjustment for open up and closed positions. World standard ISO installation pad are commonly open to provide relieve and versatility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are small and save space. They are reliable, durable and provide an excellent life routine. There are numerous brands of rack and pinion actuators available, all with subtle distinctions in piston seals, shaft seals, spring design and body designs.

Rack-and-pinion pneumatic actuators, also known as limited rotation cylinders, are rotary actuators used for turning, opening, closing, mixing, oscillating, positioning, steering and much more mechanical functions involving restricted rotation. These actuators are also frequently utilized for automation of quarter-convert valves, like ball or Gear Rack For Rack Actuator 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 required by this actuator can be provided via a central compressed air flow station, which often supports a variety of pneumatic products in a process system.
