329900983 thickened flat washer XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Dedicated Thickened Flat Washer 329900983 – The Core Guarantee of High-Strength Fastening Systems

Product Core Value

The XCMG genuine XE2000 thickened flat washer (part number: 329900983) is made of special alloy steel with a quenching process, achieving a surface hardness of HRC45-50. It is specifically designed for critical connection points in mining equipment. Certified to ISO 898-1 standards, its compressive strength is increased by 60%, effectively solving potential problems such as bolt loosening and wear on connection surfaces. It is a crucial basic component for ensuring the structural integrity of equipment.

Four Core Advantages

• Material report provided for each batch

Performance Comparison Test

Indicators: This product/Ordinary gasket
Compressive strength (MPa): 1400/850
Fatigue life (cycles): 500,000/150,000
Anti-loosening effect: No loosening after 100,000 vibrations / Loosening after 30,000 vibrations
Corrosion resistance level: Level 9/Level 5

Typical problem solutions

❌ Bolt loosening → Micro-knots increase frictional resistance

❌ Connecting surface wear → Ultra-high hardness protects the substrate

❌ Early corrosion → Triple anti-corrosion coating (phosphating + passivation + rust-preventive oil)

❌ Installation misalignment → Precise positioning chamfer design
