Washer C0430006521 is a critical pressure-distribution and shock-absorbing component for Hydraulic Rock Drills. It performs reliably in extreme mining environments. Think deep underground mines, high-altitude quarries and long tunnel construction projects.
These settings bring intense vibration (up to 22G), abrasive dust and drastic temperature fluctuations. Yet, Washer C0430006521 maintains stable performance under all these harsh conditions. It directly addresses four core pain points for mining operations.
First, it evenly distributes 140kN pressure across bolt contact surfaces. This prevents local deformation of drill components. Second, its high-elasticity design absorbs vibration effectively. This eliminates bolt loosening that disrupts drilling schedules. Third, it acts as a secondary seal to block dust and moisture. Fourth, it resists corrosion from mining slurry and humid air.
Unlike ordinary washers, this model uses 316 stainless steel as the base material. Specifically, it adds a high-elasticity rubber 夹层 (interlayer) for enhanced shock absorption. Thus, it outperforms carbon steel or standard stainless steel washers in durability.
Our manufacturing team uses precision stamping technology for consistent dimensions. The serrated top and bottom surfaces boost friction with mating parts. Additionally, heat treatment enhances its hardness to HRC 48-52, improving wear resistance.
Notably, it withstands 140kN pressure without bending or cracking. It also adapts to extreme temperatures from -50°C to 130°C. Moreover, it passes 120-hour salt spray tests with no rust or corrosion.
The washer’s universal design fits seamlessly with standard Hydraulic Rock Drill bolts. It requires no modifications to existing drill assemblies. As a result, maintenance teams can complete installation in 8 minutes with basic tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure-bearing tests, 200,000-cycle vibration trials and dimensional accuracy checks. Importantly, it complies with DIN 125A international fastener standards.
Compatible with mainstream Hydraulic Rock Drill brands, it replaces OEM parts directly. Thanks to its high durability, it reduces replacement frequency by 55%. Additionally, backed by a 12-month warranty, it cuts fastener-related failure rates by 75%.
It not only extends the service life of drill bolts by 60% but also lowers annual maintenance costs by 32%. Overall, Washer C0430006521 delivers cost-effective, reliable performance for long-term mining operations.
