XCMG XE2000 Dedicated High-Strength Washer | Part No. 318306888 | Original Factory Anti-Loosening Sealing Support Expert

In the bolt connection system of the XCMG XE2000 large excavator, high-strength washers (part number 318306888) are a core element ensuring the secure fastening of critical components. XCMG original equipment washers are specially developed for the high-load and high-vibration conditions of heavy equipment. Through special materials and processes, they provide reliable anti-loosening, sealing, and load-bearing protection for every critical connection.

▌Core Product Advantages

✅ Original factory precision matching: Designed strictly according to the technical requirements of the XE2000 bolt connection system, the inner diameter, outer diameter and thickness accuracy reach the micron level, perfectly matching the original vehicle bolts.
✅ Ultra-high strength material: Made of 65Mn spring steel or special alloy steel, with a hardness of HRC 40-45 after heat treatment, compressive strength of over 1000MPa, and will never deform.
✅ Multi-functional design: It has multiple functions such as anti-loosening, dispersing pre-tightening force, sealing and corrosion protection, effectively protecting the surface of the connecting parts and reducing stress concentration.
✅ Long-lasting corrosion protection: Surface treated with Dacromet or phosphated zinc, with a salt spray resistance test of over 500 hours, adaptable to various harsh working environments.

Typical application scenarios

Bolts are widely used in key parts of the XE2000 such as engine mounts, hydraulic pump flanges, track shoe connections, and bucket pin fixations. They are essential accessories for regular maintenance and overhaul of the equipment.

The essential difference between original and non-original parts

Non-original equipment manufacturer (OEM) washers often fail due to insufficient material hardness, dimensional deviations, or inadequate anti-corrosion processes, leading to stress fatigue, rust adhesion, or loosening failure. XCMG OEM washers (part number 318306888) undergo metallographic analysis, load testing, and salt spray testing, providing the same quality assurance as the complete machine.
