A rack and pinion is a type of linear actuator that comprises a circular gear (the pinion) engaging a linear gear (the rack), which operates to translate rotational motion into linear motion. Rack-and-pinion drives are often overlooked as past-generation technology with limited positioning accuracy. New-generation rack-and-pinion systems offer high dynamic performance and unlimited travel distance. Some include premium servo gears and actuators with backlash less than 1 arc-min., efficiency to 98.5%, and far more compact sizes…
