Circular pitch racks and pinions are designed such that a specific number of revolutions of the gear will result in an exact distance of translation on the gear rack. The pitch of a standard metric spur gear is pi*module. This results in a factional number. Circular pitch is module / pi. As such, a circular pitch of CP5, would result in a pitch of 5mm. for a 20 tooth pinion, one revolution would result in 100mm of travel. CP Racks are portions of a cylindrical disk with an infinite radius which has involute shaped teeth cut into its face. CP Racks mate exclusively with CP spur gears which have the same pitch, pressure angle and preferably face width. KHK offers CP gear racks and pinions in many materials and configurations.One unique feature of our CP racks is that most are supplied with finished ends. This type of production allows for multiple racks to be butted, end-to-end, to produce one continuous length of rack. Many of the products that we offer allow for secondary operations such as reduction of the length, the adding of tapped holes, or the application of heat treatment. Our offering also includes products which have already had some of these secondary operations completed. These products are identified by a "J" in their part number and they are available within 10 calendar days.
