A equipment rack mated with a pinion gear creates a linear actuator that converts rotational motion into linear movement or vice versa. The pinion, a circular gear, engages the teeth on the rack, a directly, 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 will cause the pinion to go in accordance with the rack. In either circumstance, the input movement is translated in to the opposite output motion.
Available in five the latest models of of stroke lengths between 10mm and 30mm, it’s simple to find the right rack and pinion linear actuator to your requirements. Special stroke lengths and custom rack and pinion gearboxes can be supplied for you personally.
Rack and pinion actuators provide a rotational movement made to open up and close quarter-convert valves such as for example ball, butterfly, or connect valves and also 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 equipment, referred to a “pinion” engages the teeth of a linear gear “bar” known as the “rack”.
Pneumatic actuators use pistons that are mounted on the rack. As atmosphere or springtime power is applied the to pistons, the rack is usually “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 could be pressurized with atmosphere, gas, or oil to provide the linear the movement that spins the pinion equipment. To rotate the pinion gear in the opposite direction, the air flow, gas, or oil should be redirected to the additional 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-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-level travel with clockwise and counterclockwise travel adjustment for open and closed positions. Globe standard ISO installation pad are commonly open to provide relieve and flexibility in direct valve installation.
Pneumatic pneumatic rack and pinion actuators are small and save space. They are reliable, durable and provide a good life routine. There are numerous brands of rack and pinion actuators out there, all with subtle differences in piston seals, shaft seals, spring design and body designs.

Our patented adjustable dual travel stops supply the greatest degree of control in the market at ±10 degrees on each end of the stroke. To check our actuators we have a complete range of control accessories including solenoid valves, limit switches, positioners, and a broad range of automation hardware.
Rack-and-pinion pneumatic actuators, also known as limited rotation cylinders, are rotary actuators used for turning, opening, closing, blending, oscillating, positioning, steering and more mechanical Gear Rack For Rack Actuator features involving restricted rotation. These actuators are also frequently utilized 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, dry, and processed gas needed by this actuator is provided via a central compressed air station, which usually supports a range of pneumatic products in a process system.
