| Dimension |
※ The dimension is the double-shaft product, while single-shaft product has no single shaft;
※ We can customize the parameters of stepper motor as your order, and add eccentric gear reducer or planetary reducer, brake and encoder etc;
※ Spigot installation with front cover is a must when seting up the motor, besides tolerance fiding should be taken into account , to secure the concentricity of output shaft and motor output.
