A gear rack mated with a Gear Rack For Window Opener pinion equipment creates a linear actuator that converts rotational movement into linear motion or vice versa. The pinion, a circular equipment, engages one’s teeth on the rack, a straight, or “linear,” gear. Rotational motion put on the pinion may cause the rack to go relative the pinion; conversely, linear motion applied to the rack may cause the pinion to move relative to the rack. In either circumstance, the input movement is translated in to the opposite output motion.

Available in five different models of stroke lengths between 10mm and 30mm, it’s easy to find the appropriate rack and pinion linear actuator for your needs. Special stroke lengths and custom 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 ball, butterfly, or connect valves and in addition for operating industrial or commercial dampers.
The rotational movement 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 equipment “bar” known as the “rack”.
Pneumatic actuators use pistons that are attached to the rack. As air flow 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 could be pressurized with atmosphere, gas, or oil to provide the linear the motion that spins the pinion gear. To rotate the pinion gear in the contrary direction, the air, gas, or oil must be redirected to the other sides of the piston, or use coil springs as the power source for rotation. Rack and pinion actuators using springs are known as “spring-come back actuators”. Actuators that depend on opposite aspect pressurization of the rack are referred to as “direct acting”.
Most actuators are made for 100-degree travel with clockwise and counterclockwise travel adjustment for open up and closed positions. World 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 dependable, durable and provide a good life routine. There are various brands of rack and pinion actuators out there, all with subtle distinctions in piston seals, shaft seals, spring design and body designs.

To check our actuators we have a complete selection 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, mixing, oscillating, positioning, steering and more mechanical features involving restricted rotation. These actuators are also often used for automation of quarter-switch 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 required by this actuator is usually provided with a central compressed air flow station, which often supports a range of pneumatic gadgets in an activity system.
