Machine Keys / Key Materials
Machine key / Key material machine key is a fitting that is used to fix a pulley or gear to a rotating shaft. It is often used for motors and reducers, and is built into various machines. Because it is a component for power transmission, it is characterized by excellent strength and precision machining with few errors. Machine keys are roughly divided into three types according to parallel keys, gradient keys, headed gradient keys, and their shapes. In addition, there are various variations depending on the square and round shape of the edge processing. Let's choose an appropriate one according to the size of the keyway of the rotating shaft and the parts fixed to the shaft.
