A gear rack mated with a pinion equipment creates a linear actuator that converts rotational motion into linear movement or vice versa. The pinion, a circular equipment, Gear Rack For Window Opener 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 may cause the pinion to move in accordance with the rack. In either situation, the input motion is translated into the opposite output motion.
Available in five different models of stroke lengths between 10mm and 30mm, it’s easy to find the right rack and pinion linear actuator to your requirements. Special stroke lengths and custom rack and pinion gearboxes could be supplied to meet your requirements.
Rack and pinion actuators provide a rotational movement designed to open up and close quarter-change valves such as for example ball, butterfly, or connect 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 gear “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are attached to the rack. As air or springtime power is used the to pistons, the rack is “pushed” inward or “pulled” outward. This linear motion is transferred to the rotary pinion equipment (in both directions) providing bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with atmosphere, gas, or oil to provide the linear the movement that spins the pinion equipment. To rotate the pinion equipment in the opposite direction, the atmosphere, gas, or oil should be redirected to the other sides of the piston, or make use of 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 aspect pressurization of the rack are referred to as “direct acting”.
Most actuators are created for 100-degree travel with clockwise and counterclockwise travel adjustment for open up and closed positions. World standard ISO installation pad are commonly open to provide ease and flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are small and save space. They are dependable, durable and provide an excellent life routine. There are various brands of rack and pinion actuators in the marketplace, all with subtle variations in piston seals, shaft seals, spring design and body designs.

To complement our actuators we’ve a complete range of control add-ons which includes solenoid valves, limit switches, positioners, and a wide range 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 many more mechanical features involving restricted rotation. These actuators are also frequently utilized for automation of quarter-convert 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 needed by this actuator can be provided 
via a central compressed atmosphere station, which often supports a variety of pneumatic gadgets in a process system.
