ISO class 5 rectangular ground racks and joining gauges are available in Modules 0.5, 0.8, 1, 1.5, and CP 2 and 5. Gear racks are used to convert rotational motion into linear motion. In theory, a rack is an unrolled gear with an infinite pitch diameter and will mesh with all gears of the same pitch. Modules 0.5, 0.8, 1, and 1.5 are identified as the S18C Series and the CP 2 and 5 are known as the S18CCPM Series. Both series are available with machined ends that allow them to be joined together to create continuous rack lengths.
