380902677 XCMG GR2605 motor grader rubber sleeve

380902677 Rubber sleeves are core cushioning components for the connection parts of engineering machinery and equipment. They are mainly used for sealing, cushioning, and protection at shafts, pipes, and interfaces. Suitable for various engineering machinery and industrial equipment connection parts, they fill installation gaps, absorb vibration, prevent friction and wear between components, and also provide dust and corrosion protection. They are fundamental components ensuring stable equipment operation.

Core Technical Parameters

Material: High-quality nitrile rubber (oil-resistant, wear-resistant, and aging-resistant), custom-made versions are available to meet special requirements such as temperature resistance, oil resistance, and acid and alkali resistance.

Specifications: Inner diameter adapts to corresponding shaft diameter/pipe size; thickness 3-5mm; length customized as needed; adaptable to various equipment interfaces.

Operating Temperature: -40℃~80℃; stable operation in harsh environments without deformation or cracking.

Sealing Performance: Suitable for high-pressure conditions; leak-proof; effectively isolates dust and moisture, protecting internal components.

Suitable Scenarios: Shafts, pipes, and interfaces in engineering machinery and industrial equipment for cushioning, sealing, and protection.

Core Functions and Roles

**Buffering and Vibration Reduction:** Absorbs vibrations during equipment operation, reduces collisions and friction between components, lowers abnormal noise, and protects core components from damage.
**Sealing and Protection:** Fills installation gaps, isolates dust, moisture, and oil, prevents internal component corrosion and wear, and extends equipment lifespan.
**Adaptive Connection:** Precisely matches corresponding shaft diameters and pipe sizes, facilitating easy installation without additional adjustments and directly adapting to equipment interfaces.
**Protective Function:** Prevents direct friction between shafts/pipes and installation areas, reducing wear, while also providing insulation and corrosion protection.

Suitable Scenarios and Usage Notes

This product is compatible with shafts, pipes, and interfaces of various construction machinery (excavators, loaders, etc.) for cushioning, sealing, and protection. It is suitable for heavy-duty and outdoor working conditions. During installation, clean any impurities from the interface to ensure a tight fit between the rubber sleeve and the connection. Avoid forcing it in, which could cause damage. For routine maintenance, keep the rubber sleeve clean, avoid scratches from sharp objects, and keep it away from high temperatures and highly corrosive environments to prevent aging. If cracking, aging, or deformation occurs, replace it promptly to avoid affecting the equipment’s sealing and cushioning performance.
