Gear Racks

A rack gear is a rack-type gear that has been cut into a flat bar. By combining with a normal round gear, it is possible to convert rotational motion into linear motion. It is used for automobile steering and telescope focusing. Since it is basically a set with gears, you must choose one that matches the tooth surface. There is also a resin rack gear that can change its shape freely, and it can be used for a wide range of applications such as original work.
