1. Primary Functions

• Prevent Contaminants from Entering: Rubber dust cover sleeves are used to cover moving or critical components such as bearings, joints, pistons, and electrical connectors. They prevent dust, grease, moisture, or other external contaminants from entering and damaging the components.
• Extend Equipment Life: By reducing the wear and tear caused by external particles, the protective sleeve extends the lifespan of the components or equipment, thereby reducing the risk of malfunctions.
• Maintain Stable Performance: Exposure to contaminants can affect the performance of mechanical devices. Using dust cover sleeves helps keep the machinery running smoothly, avoiding performance degradation.

2. Common Applications

• Automotive Industry: In the automotive suspension system, rubber dust sleeves are often used to protect shock absorbers, ball joints, and drive shafts from damage caused by dirt, gravel, and water.
• Industrial Machinery: In industrial equipment, moving bearings, transmission mechanisms, and other exposed parts are often subject to harsh environments. Rubber dust sleeves provide excellent protection in such conditions.
• Electrical Connections: Rubber dust sleeves are used on cable connectors, power plugs, and other electrical connections to prevent moisture and dust from entering, ensuring that circuits are not shorted or otherwise compromised.
