A equipment 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 one’s teeth on the rack, a straight, or “linear,” equipment. Rotational motion applied to the pinion will cause the rack to move relative the pinion; conversely, linear motion put on the rack will cause the pinion to move relative to the rack. In either circumstance, the input motion is translated into 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 to meet your requirements.
Rack and pinion actuators provide a rotational movement designed to open up and close quarter-convert valves such as ball, butterfly, or plug valves and also for operating commercial 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 the teeth of a linear gear “bar” referred to as the “rack”.
Pneumatic actuators use pistons that are attached to the rack. As surroundings or spring power is applied the to pistons, the rack is “pushed” inward or “pulled” outward. This linear movement is used in the rotary pinion equipment (in both directions) offering bi-directional rotation.
Rack and pinion actuators pistons can be pressurized with atmosphere, gas, or essential oil to supply the linear the movement that spins the pinion gear. 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 power source for rotation. Rack and pinion actuators using springs are referred to as “spring-return actuators”. Actuators that depend on opposite side 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. Globe standard ISO mounting pad are commonly available to provide relieve and flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are dependable, durable and provide an excellent life cycle. There are plenty of brands of rack and pinion actuators on the market, all with subtle distinctions in piston seals, shaft seals, spring design and body designs.

Rack-and-pinion pneumatic actuators, also called limited rotation cylinders, are rotary actuators used for turning, opening, closing, combining, oscillating, positioning, steering and more mechanical features involving restricted rotation. These actuators are also often used for automation of quarter-turn valves, like ball or butterfly valves.
Pneumatic rack-and-pinion actuators convert the energy of compressed air through a pneumatic cylinder to an oscillating rotary motion. The clean, dried out, and processed gas necessary by this actuator is definitely provided with a central compressed air flow station, which often supports a variety of pneumatic products in an activity system.
