When discussing the role of bearings in air conditioners, we first need to understand the basic functions of bearings and how air conditioners work.

Bearing is a component widely used in mechanical equipment. Its main function is to support the rotating body and reduce its friction coefficient during movement while ensuring the flexibility of rotation. Bearings usually carry radial and axial loads and allow relative movement of the shaft within the bearing housing.

For air conditioners, it is a device that regulates indoor temperature and humidity. In an air conditioning system, there are multiple parts and components that work together to transfer heat and circulate air. Among them, many moving parts, such as fans, compressors and some transmission systems, may require bearings to support their rotational motion.
