Description: Micro DC geared motor has stable performance, larger torque and smaller sound. Upgraded version of the gears all use metal gears, the transmission is smooth, wear-resistant, difficult to tooth, large transmission torque, and extend the life of the motor. With a magnet design, which greatly improves the performance of the motor. Pure copper motor has a larger diameter, a larger torque of the motor, and a faster power output of the motor. 3-layer high-density molecular coating has a drip coating that effectively isolates dust from high temperatures and has a lifetime 10 times that of a normal coating. Ball bearing has hard mechanical characteristics, good stability and control, no slip loss and high efficiency. Specification: Material: metal Product size: 130x59x59mm Package Includes: 1Piece DC Gear Motor Note: Please allow 0-1cm difference due to manual measurement.(1cm=0.39inch, 1inch=2.54cm) Due to the difference between different monitors, the picture may not reflect the actual color of the item.
