We’re happy to help you find the best option for your application.
In the field of heavy construction machinery, the stability of every connection point is crucial to the safety of the entire machine. As an industry flagship model, the XCMG XE2000 excavator’s fasteners in critical components must withstand extreme working conditions. Now, we are launching military-grade thickened washers (part number: 805338279, specification 10), specifically designed for the XE2000’s overload operation, providing ultimate protection for the equipment!
⚡ Double Thickened Design: Made with special alloy steel stamping, twice the thickness of standard washers, increasing compressive strength by 300%.
🔧 Nano Coating Technology: Unique DLC diamond-like carbon coating, achieving corrosion resistance up to ASTM B117-1000h standard.
🛡️ Extreme Adaptability: Maintains stable performance under operating conditions of -50℃ to 200℃, increasing shear resistance by 5 times.
📏 Zero-Error Matching: Precision CNC machining, perfectly fitting XE2000 bolts of all specifications.
1️⃣ Solves the problem of joint surface deformation caused by heavy-load impact.
2️⃣ Each piece can be reused more than 8 times, reducing maintenance costs by 70%.
3️⃣ Certified by ISO 9001/CE/Mining Safety Triple Certification.
4️⃣ Surface hardness HRC58, wear resistance 10 times that of ordinary washers.
5️⃣ Provides stress distribution analysis report
▸ Slewing bearing bolt assembly reinforcement
▸ Boom hinge anti-loosening
▸ Hydraulic breaker mounting position
▸ Equipment modification and reinforcement areas
“In a mining area at an altitude of 5000 meters in Tibet, after using 805338279 washers, the bolt loosening failure rate decreased by 95%”—Mining equipment manager of a central state-owned enterprise
