ZDM270 Linear Module with speed 1ms heavy load 100~200kg Linear Actuator for stroke 100-2700mm Rack Type Electric Module

1. Rack and pinion drive is a kind of transmission method that transmits the motion and power of the active sprocket with special tooth shape to the driven sprocket with special tooth shape through chain.

2. Rack transmission has many advantages, compared with belt transmission, there is no elastic sliding and slipping phenomenon, the average transmission ratio is accurate, the work is reliable and the efficiency is high; the transmission power is large, the overload capacity is strong, the transmission size is small under the same working condition; the required tension force is small, the pressure acting on the shaft is small; it can work in the high temperature, humid, dusty, polluted and other harsh environments.
