Rack and pinion is utilized to convert rotational motion to linear motion. A rack is straight teeth cut into one surface of rectangular or cylindrical rod shaped material, and a pinion is a small cylindrical gear meshing with the rack. There are many ways to categorize gears. If the relative position of the gear shaft is used, a rack and pinion belongs to the parallel shaft type.

We provide custom gear racks in metric standards, straight and helical tooth, various materials, fine and coarse pitch (0.5 Module – 20 Module), max width 150mm, lengths 2000mm, tooth finish include milling, shaping, ground etc,Precise grade up to DIN 6/JGMA 2
