In many remote control models, whether rc model cars or rc model aircraft, rc bearings are the indispensable main transmission components. Some rc bearings are used on servers, some on wheels, and some on micro motors. All parts that need to be driven are inseparable from the rc bearings, so the quality of the rc bearings will largely determine the overall quality, service life and experience of the remote control model.
