A equipment rack mated with a pinion gear creates a linear actuator that converts rotational motion into linear movement or vice versa. The pinion, a circular gear, engages one’s teeth on the rack, a straight, or “linear,” gear. Rotational motion put on the pinion may cause the rack to move relative the pinion; conversely, linear motion put on the rack will cause the pinion to go in accordance with the rack. In either circumstance, the input motion is translated into the opposite output motion.
Available in five different models of stroke lengths between 10mm and 30mm, it’s simple to find the right rack and pinion linear actuator for your needs. Special stroke lengths and custom rack and pinion gearboxes can be supplied to meet your requirements.
Rack and pinion actuators provide a rotational movement designed to open up and close quarter-switch valves such as ball, butterfly, or plug valves and also for operating industrial or commercial dampers.
The rotational movement of a rack and pinion actuator is accomplished via linear motion 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 atmosphere or springtime power is applied the to pistons, the rack is certainly “pushed” inward or “pulled” outward. This linear movement is used in the 
rotary pinion gear (in both directions) providing bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with air, gas, or oil to provide the linear the movement that spins the pinion equipment. To rotate the pinion gear in the contrary direction, the surroundings, gas, or oil should 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-arrive back actuators”. Actuators that depend on opposite part pressurization of the rack are known as “direct acting”.
Most actuators are created for 100-level travel with clockwise and counterclockwise travel adjustment for open and closed positions. Globe standard ISO installation pad are commonly available to provide relieve and versatility 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 many brands of rack and pinion actuators on the market, all with subtle distinctions in piston seals, shaft seals, spring design and body designs.

Our patented adjustable dual travel stops supply the greatest degree of control in the industry at ±10 degrees upon each end of the stroke. To check our actuators we have a complete range of control accessories including solenoid valves, limit switches, positioners, and a wide assortment of automation hardware.
Rack-and-pinion pneumatic actuators, also known as limited rotation cylinders, are rotary actuators used for turning, opening, closing, combining, oscillating, positioning, steering and much more mechanical functions involving restricted rotation. These actuators are also Gear Rack For Window Opener 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 necessary by this actuator is provided via a central compressed air flow station, which usually supports a variety of pneumatic gadgets in an activity system.
