800168951 semi-circle key XCMG XE2000 excavator spare parts

XCMG XE2000 excavator semi-circular key (part number 800168951) – the core of precision connection of the transmission system!

Military-grade material with zero-error adaptation

The semi-circular key (800168951), specially designed for the XE2000 transmission system, is precision forged from high-strength alloy steel (42CrMo) and achieves a hardness of HRC50-54 after vacuum heat treatment. Coordinate measuring machine (CMM) testing shows that the arc surface fit is ≥98%, completely solving persistent problems such as keyway wear and transmission noise.

Five major technological breakthroughs

🔧 Nanoscale grinding: Surface roughness Ra 0.2μm, fit gap ≤ 0.01mm
⚡ Gradient hardening process: Perfect balance between core toughness and surface hardness
💧 Anti-fretting wear coating: Reduces fretting wear rate by 80%
🔥 Low-temperature impact toughness: Maintains 35J impact energy even at -40℃
📊 Intelligent Marking System: Laser Engraving and Installation Phase Angle
