A gear rack is a type of linear actuator that comprises a circular gear (the pinion) engaging a linear gear (the rack). Together, they convert rotational motion into linear motion. Rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate. A rack and pinion drive can use both straight and helical gears. Though some suggest helical gears are quieter in operation, no hard evidence supports this theory.

Rack and pinion combinations are often used as part of a simple linear actuator, where the rotation of a shaft powered by hand or by a motor is converted to linear motion. The rack carries the full load of the actuator directly and so the driving pinion is usually small, so that the gear ratio reduces the torque required. This force, thus torque, may still be substantial and so it is common for there to be a reduction gear immediately before this by either a gear or worm gear reduction.

Rack and pinion gears are also used in a variety of other applications, such as:

• Steering systems in cars and trucks
• Machine tools
• Robotics
• Conveyor belts
• Wind turbines
• And many more

Rack and pinion gears are versatile and reliable type of gear that can be used in various applications. If you are looking for a way to convert rotary motion into linear motion, then a rack and pinion gear is a good option.
