Gear Racks

Racks are portions of a cylindrical disk with an infinite radius which has involute shaped teeth cut into its face. Racks mate exclusively with spur gears which have the same module, pressure angle and preferably face width. KHK offers gear racks in many materials, configurations, modules and lengths. One unique feature of our 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.
