Bicycle mid-mounted motor bearing is a bearing designed for electric bicycles. It uses smooth metal balls or rollers and lubricated inner and outer ring metal surfaces to reduce friction, support the motor spindle, and allow the motor (rotor) to rotate smoothly. ‌

This type of bearing usually uses rolling bearings, with ball bearings at both ends of small and medium-sized motors, roller bearings at the load end of medium-sized motors, and ball bearings at the non-load end. ‌ The main function of the bicycle mid-mounted motor bearing is to reduce friction and wear during motor operation, improve the operating efficiency and life of the motor. It can carry loads, keep the motor stable at high speeds, reduce vibration and noise, and thus improve the overall riding experience and motor performance. ‌ 

Bicycle wheel bearings usually consist of two main components: the axle and the hub. These two components are connected together by bearing balls and roller bearings to achieve rotation and movement. In order to achieve better sports performance, high-end mountain electric-assisted bicycles usually adopt a mid-mounted motor solution. The mid-mounted motor allows the rider to ride more smoothly, the body is more balanced and stable, the climbing ability is strong, and the rider's burden is reduced. Whether it is bicycle bearings or mid-mounted motors, we, RCL, can supply a large number of related bearings and services.
