Bearings are a vital component of wall-mounted fan motors, which directly affect the smooth operation, noise level and service life of the motor. Different types of bearings have different characteristics and advantages, so when choosing a wall-mounted fan, bearing type is one of the key factors to consider.
Friction and energy consumption
Ball bearings: Ball bearings use balls to reduce friction, so they have a lower friction coefficient and can reduce the energy consumption of the motor. This means that the wall-mounted fan motor uses ball bearings to rotate more efficiently, making the fan more efficient and energy-saving.
Sliding bearing: Sliding bearing uses sliding friction to support the bearing, so the friction coefficient is large, which will cause a certain degree of energy loss. This means that wall-mounted fan motors using sliding bearings may require more energy to maintain rotation, thus affecting the fan's efficiency and energy consumption.
Smooth operation
Ball bearings: Because ball bearings use balls to support the bearings, they have smaller friction and higher rotational accuracy, ensuring the smooth operation of the motor. This means that the wall-mounted fan motor uses ball bearings to reduce vibration and noise and improve the user experience.
Sliding bearings: Sliding bearings will generate large friction during operation, which may cause the motor to run unevenly and cause jitter or noise. This will affect the performance of the wall-mounted fan and reduce user comfort.
Service life
Ball Bearings: Ball bearings generally have a long service life because ball bearings use rolling friction, which reduces friction and wear, extending the life of the bearing and motor. This means that the wall-mounted fan motor using ball bearings can be more durable and reduce the frequency of maintenance and replacement.
Sliding bearings: Sliding bearings use sliding friction and are prone to wear, so their service life is relatively short. Wall-mounted fan motors using sliding bearings may require more frequent maintenance and replacement, increasing usage and maintenance costs.
Temperature and environmental adaptability
Ball bearings: Ball bearings are usually able to withstand higher speeds and temperatures, have better heat resistance and wear resistance, and are suitable for wall-mounted fan motors under various environmental conditions.
Sliding bearings: Sliding bearings use sliding friction and are prone to wear and heat. Therefore, their heat resistance and wear resistance are relatively poor, and they may not be suitable for high temperature or high-speed operation environments.
