Washer C0430000331 is a critical pressure-distribution component for Hydraulic Rock Drills. It performs reliably in harsh mining environments. Examples include deep underground mines, rough open-pit quarries and tunnel construction sites.
These settings involve intense vibration (up to 20G), heavy dust and extreme temperature swings. Yet, Washer C0430000331 maintains stability under all these conditions. It directly solves three core pain points for mining operations.
First, it evenly distributes bolt pressure across contact surfaces. This prevents component deformation from concentrated loads. Second, it features an anti-loosening serrated design that locks bolts in place. This eliminates vibration-induced loosening that halts drilling tasks. Third, it acts as a secondary seal to block dust and moisture.
Unlike ordinary flat washers, this model uses 304 stainless steel for durability. Specifically, the material offers excellent corrosion resistance and tensile strength. Thus, it outperforms carbon steel washers in humid mining environments.
Our manufacturing team precision-stamps each washer for consistent dimensions. The serrated bottom surface enhances friction with mating parts. Additionally, heat treatment boosts its hardness to HRC 45-50 for wear resistance.
Notably, it withstands 120kN pressure without bending or cracking. It also adapts to temperature ranges from -40°C to 120°C. Moreover, it passes 100-hour salt spray tests with no rust or corrosion.
The washer’s compact design fits seamlessly with standard drill bolts. It requires no modifications to existing Hydraulic Rock Drill assemblies. As a result, installation is quick and hassle-free for maintenance teams.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure-bearing tests, 150,000-cycle vibration trials and dimensional accuracy checks. Importantly, it complies with DIN 125 international fastener standards.
Compatible with mainstream Hydraulic Rock Drill brands, it replaces OEM parts directly. Thanks to its universal fit, it reduces inventory costs for mining firms. Workers can install it in 10 minutes using basic hand tools.
No specialized training or custom fixtures are needed. Additionally, backed by a 12-month warranty, it cuts fastener-related failure rates by 70%. It not only extends bolt service life by 50% but also lowers maintenance downtime by 35%.
Overall, Washer C0430000331 delivers cost-effective, reliable performance for long-term mining operations.
