Bearing C0300010051 is a critical load-bearing component for Hydraulic Rock Drills. It performs reliably in extreme mining environments. Think deep underground mines, rugged open-pit quarries and long-distance tunneling projects.
These settings present intense vibration (up to 18G), heavy abrasive dust and drastic temperature shifts. Yet, Bearing C0300010051 excels under all these harsh conditions. It directly addresses three key industry pain points for mining firms.
First, it eliminates premature wear caused by continuous heavy-load operation. Second, it prevents dust-induced jamming that disrupts drilling schedules. Third, it resists corrosion from mining slurry and humid underground air.
Unlike ordinary single-sealed bearings, this model features a double-sealed structure. Specifically, it combines rubber lip seals and metal shields for 360° protection. Thus, it blocks 99.5% of debris and moisture from entering the inner ring.
Our engineering team crafts it with premium GCr15 chrome steel. This material delivers exceptional wear resistance and mechanical strength. Additionally, precision grinding achieves ±0.002mm dimensional tolerance for tight fits.
Notably, quenching and tempering treatment boosts its hardness to HRC 62-64. It withstands 190kN radial load without deformation. It also maintains stable rotation at 5500rpm for 15,000 consecutive working hours.
Moreover, it uses high-temperature synthetic grease for lubrication. The grease performs reliably across -40°C to 130°C. As a result, it reduces maintenance frequency by 45% compared to standard bearings.
The surface undergoes zinc-nickel plating treatment. It passes 150-hour salt spray tests with no rust or coating peeling. Our quality team conducts strict ISO 9001 verification for every unit.
We perform 120,000-cycle rotational fatigue tests, load-bearing trials and sealing performance checks. Importantly, it complies with ISO 3408-7 international mining equipment standards.
Compatible with mainstream Hydraulic Rock Drill brands, it fits seamlessly. Thanks to its press-fit design, installation is straightforward. Workers can replace it in 18 minutes using standard tools.
No specialized training or custom modifications are required. Additionally, backed by a 12-month warranty, it cuts rotating component failure rates by 65%. It not only extends drill system service life by 40% but also lowers annual maintenance costs by 30%.
Overall, Bearing C0300010051 delivers durable, cost-effective reliability for long-term mining operations.
