The dust-proof sleeve of automobile ball cage is a sleeve made of rubber or silica gel installed outside the ball cage, which is used to protect the key parts inside the ball cage from the invasion and damage of external impurities such as dust, water vapor and sediment. In the internal and external aspects of the ball cage dust cover, there are mainly the following differences:

1. Material: The inside and outside of the cage dust jacket are usually made of different materials. The exterior is usually made of wear-resistant and aging-resistant materials such as rubber or silica gel to provide better dustproof, waterproof and protective performance; The interior is usually made of smooth material to reduce the friction and wear on the internal parts of the cage.

2. Structure: The internal structure of the dust cover of the ball cage is usually designed as a smooth surface to reduce friction and wear and protect the internal parts of the ball cage from damage; The external structure is usually designed as a corrugated or uneven surface to increase dust-proof, waterproof and wear-resistant performance.

3. Function: The inside of the cage dust jacket mainly plays the role of reducing friction, protecting parts and preventing dust from entering; The exterior mainly plays the role of dustproof, waterproof and protecting the cage and parts.

4. Installation position: the inside of the dust cover of the ball cage directly covers the key parts outside the ball cage to protect and reduce friction; While the outside is directly exposed to the external environment, which bears the functions of dustproof, waterproof and cage protection.

To sum up, there are some differences between the inside and outside of the dust cover of the automobile ball cage in terms of material, structure, function and installation position, but they work together to protect the automobile chassis ball cage and its internal parts, ensure the normal operation of the automobile chassis system and prolong the service life of the parts.
