Three levels of precision are now available, with pitch accuracies down to 0.012 mm per 1,000 mm length. This gives the machine designer the flexibility of choosing the desired level of rack precision to meet the application needs. These racks are available in straight (spur) and helical versions, in modules 2.0 through 12.0, in half meter and one meter lengths. These racks are ideal for high accuracy applications requiring minimal pitch error over the complete travel length. The high precision pitch of the racks can eliminate the need for electronic compensation and the high precision parallelism allows for drives with extremely low backlash without the need for preloading. Used with our split-pinions, ultra-precise zero-backlash axis drives can be achieved. Rack Range:
The quality levels denote the accuracy of the teeth, which affects the positioning accuracy, backlash and noise level of the rack & pinion set.
Helical Racks:
To set the pitch in-between rack segments, a companion rack is typically used. While this works well for most applications, it can induce error into the axis. This error can accumulate with each rack joint, especially on long axis drives. When using our Precision Hardened & Ground Racks in high accuracy applications, we recommend using our Rack Assembly Kits to achieve the most accurate pitch in-between rack segments. The assembly kit consists of a measuring bridge, an adjusting device and magnetic rollers. With this kit, it is possible to achieve perfect rack joints without adding error to the system. A video showing how the Rack Assembly Kit is used can be found on our Instructional Videos page.
