805338299 XCMG GR2605 motor grader washer

The 805338299 washer is a specialized auxiliary accessory for connection parts in construction machinery. It is used for load distribution, sealing protection, and preventing loosening. Suitable for heavy-duty and high-frequency vibration conditions, it features a simple structure and convenient installation, making it a fundamental and easily worn component in equipment assembly and maintenance.

Core Technical Parameters

1. Model: 805338299, a dedicated washer for construction machinery; there is no universal alternative.

2. Compatible Media: No specific media required; suitable for various connection parts in construction machinery.

3. Material: High-quality carbon steel/stainless steel, high strength, high toughness, compression resistant, and not easily deformed.

4. Operating Temperature: -40℃~120℃, suitable for harsh outdoor working environments such as humidity and dust.

5. Surface Treatment: Blackening treatment/galvanized passivation, rust and corrosion prevention, and improved wear resistance.

6. Specifications and Dimensions: Inner diameter, outer diameter, and thickness are compatible with standard connection interfaces in construction machinery; no additional adjustments are required.

7. Load-bearing capacity: Effectively distributes axial loads, avoids localized stress concentration, and is suitable for heavy-duty conditions.

8. Fitting precision: Precisely matches bolts and connecting holes, ensuring a secure, gapless installation and excellent sealing performance.

Core functions and effects

Distributes load: Evenly distributes axial pressure on bolts and connectors, preventing localized stress concentration that could lead to component wear and damage, thus extending the service life of the connection structure; Sealing and protection: Fills gaps in the connection area, isolates dust, moisture, and oil, prevents internal component corrosion, and improves system sealing; Anti-loosening and fixing: Used with bolts and nuts to enhance the tightness of the connection, reducing loosening and displacement caused by vibration during equipment operation; Buffering and shock absorption: Absorbs minor vibrations and impacts during operation, reducing wear on connectors and ensuring the stability of the connection.

Suitable Applications

Washers are widely used in bolt connections, shaft hole assemblies, and hydraulic pipeline connections in various construction machinery such as excavators, loaders, bulldozers, and mining machinery. They are suitable for heavy-duty, high-frequency vibration operations in infrastructure construction, mining, earthwork engineering, and road construction, making them an indispensable basic auxiliary component in equipment connection structures.

Common Faults and Troubleshooting

When washers are deformed or broken, check for excessive axial load or excessive installation tightening force. Replace with washers of appropriate specifications and optimize assembly parameters. When washers become loose or fall off, check for washer wear and bolt loosening. Retighten bolts and replace severely worn washers. When rust or corrosion occurs, check for damage to the surface protective layer and environmental corrosion. Replace with galvanized washers and ensure proper protection of the connection area. When a seal fails, the aging or wear of the washers reduces the sealing effect. Replace with new washers promptly to ensure the sealing performance of the connection.
