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 one’s teeth on the rack, a directly, or “linear,” gear. Rotational motion put on the pinion may cause the rack to go relative the pinion; conversely, linear motion put on the rack will cause the pinion to move in accordance with 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 easy to find the right rack and pinion linear actuator to your requirements. Special 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-switch valves such as for example ball, butterfly, or plug valves and in addition for operating commercial or commercial dampers.
The rotational movement 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 equipment “bar” known as the “rack”.
Pneumatic actuators use pistons that are attached to the rack. As surroundings or springtime power is applied the to pistons, the rack is certainly “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 gear in the opposite direction, the air, gas, or oil should be redirected to the various other sides of the piston, or use coil springs as the power source for rotation. Rack and pinion actuators using springs are referred to as “spring-return actuators”. Actuators that rely on opposite side pressurization of the rack are referred to as “direct acting”.
Most actuators are designed for 100-degree travel with clockwise and counterclockwise travel adjustment for open 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 reliable, durable and provide an excellent life routine. There are several brands of rack and pinion actuators on the market, all with subtle differences in piston seals, shaft seals, spring style and body designs.

To complement our actuators we have a complete range of control accessories including solenoid valves, limit switches, positioners, and a wide range of automation hardware.
Rack-and-pinion pneumatic actuators, also called limited rotation Gear Rack For Rack Actuator 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 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, dried out, and processed gas necessary by this actuator is usually provided via a central compressed surroundings station, which often supports a variety of pneumatic gadgets in an activity system.
