Classification of Automobile Bearings by Material

Classification by Material

Metal Bearings: Made of metal materials such as steel, copper, and aluminum, they have the advantages of high durability and reliability. Capable of withstanding large loads and rotational speeds, they are the main type of automotive bearings.

Plastic Bearings: Made of plastic materials, they offer advantages like light weight, low cost, and low noise. However, their load-bearing capacity and heat resistance are relatively poor, making them suitable for low-speed and light-load applications, such as automotive interior parts and air conditioning systems.

Classification by Purpose and Application Field

General-Purpose Bearings: Suitable for multiple uses, they can be applied in different types of automotive components and have high versatility and interchangeability.

Special-Purpose Bearings: Designed for specific application requirements, such as hub bearing units, universal joint bearings, and clutch release bearings. These bearings have unique structures and performance characteristics to meet the working requirements of specific automotive components.
