Racks are portions of a cylindrical disk with an infinite radius which includes involute shaped the teeth cut into its encounter. Racks mate specifically with spur gears which have the same module, pressure position and preferably encounter width. KHK offers equipment racks in many materials, configurations, modules and lengths. One unique feature of our racks is definitely that most are given finished ends. This type of production allows for multiple racks to be butted, end-to-end, to produce one continuous amount of rack. Most of the products that we offer allow for secondary procedures such as for example reduction of the distance, the adding of tapped holes, or the application of heat treatment. Our offering also contains products which have already had some of these secondary operations completed.
The straight tooth cylindrical gear that the radius of the pitch cylinder is infinite and in a bar form is called a gear rack. If it’s sorted by the positions of the gear shafts, it belongs to the parallel shaft category. The spur gear that meshes with a gear rack is generally called a pinion.
Besides equipment racks with straight collection tooth, there are helical racks which have slanted teeth. Helical gear racks are paired with helical gears, but because of the slant of the 
tooth direction, as in helical gears, the mesh Metric Gear Rack creates axial thrust forces.
Among the apparatus racks’ primary applications are machine equipment and transport devices so when the applications involve transmitting linear motions, they are often compared with ball screws. In those instances, the main advantages of gear racks could be named this kind of as being able to satisfy a heavier load through the use of larger modules and having no length limitation by connecting equipment racks with completed ends. However, an example of the disadvantages of equipment racks includes the occurrence of backlash.
When manufacturing equipment racks, due to their bar shape, bending often results. In these cases, corrective processes using presses are often employed.
