Features Lower Noise and Longer Service Life: All-metal gears will ensure longer service life, high torque and lower noise, 3-layer high-density molecular paint coating, which effectively isolates dust and resists high temperature. A Variety of Speeds for Your Choice: There are a variety of reduction gear motors with different speeds, you can choose the one you need, the motor has strong power output, low heat dissipation and low loss, and is a good substitute for the old electronic gear motor. Wide Range of Applications: Gear motors can be found in many different applications and may be used in many devices in your home, DC motors, mainly for electronic locks, smart cars, robots, cameras, etc. Linear Stepping Motor: The output shaft is a threaded screw, which can easily make a mobile transmission structure with a nut, and you can use it with confidence. Generate More Torque: This gear motor lead screw is mainly used to reduce the speed of a series of gears, the gear transmission is smoother, resulting in more torque, low noise, and easy to use.
