A gear rack mated with a pinion equipment creates a linear actuator that converts rotational movement into linear movement or vice versa. The pinion, a circular gear, engages the teeth on the rack, a straight, or “linear,” gear. Rotational motion applied to the pinion will cause the rack to move relative the pinion; conversely, linear motion applied to the rack may cause the pinion to move relative to the rack. In either scenario, 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 easy to find the right 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 and close quarter-turn valves such as for example ball, butterfly, or connect valves and also for operating industrial or commercial dampers.
The rotational motion of a rack and pinion actuator is accomplished via linear movement and two gears. A circular gear, referred to 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 flow or springtime power is used the to pistons, the rack is “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 can be pressurized with atmosphere, gas, or essential oil to provide the linear the movement that spins the pinion equipment. To rotate the pinion equipment in the contrary direction, the surroundings, gas, or oil should be redirected to the various 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-come back actuators”. Actuators that rely on opposite part pressurization of the rack are known 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 mounting pad are commonly available to provide relieve and versatility in direct valve set up.
Pneumatic pneumatic rack and pinion actuators are compact and save space. They are dependable, durable and provide an excellent life routine. There are many brands of rack and pinion actuators out there, all with subtle distinctions in piston seals, shaft seals, spring style and body designs.

Rack-and-pinion pneumatic actuators, also called limited rotation cylinders, are rotary actuators used for turning, opening, closing, mixing, oscillating, positioning, steering and more mechanical functions involving restricted rotation. These actuators are also often used for automation of quarter-change 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 usually provided with a central compressed air flow station, which usually supports a variety of pneumatic gadgets in a process system.
