Bushing 6060704114 is a critical wear-resistant structural accessory exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground hard rock drill pivot points, high-load drill arm joints, and vibration-intensive drill shaft assemblies.
These settings pose severe challenges for drill bushings: continuous metal-to-metal friction, heavy load-bearing (up to 40MPa), abrasive rock dust, humid/corrosive air, and extreme temperature swings. These issues often cause bushing wear, seizing, corrosion, or misalignment, leading to drill component damage and costly downtime. Yet, Bushing 6060704114 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its bronze alloy base + tungsten carbide insert achieves HRC 62-65 surface hardness, resisting wear from continuous friction better than standard steel bushings. This extends service life by 180% and reduces replacement frequency by 40%. Second, the self-lubricating graphite grooves embedded in the bronze matrix eliminate the need for frequent lubrication. Consequently, it avoids seizing even in dusty environments where lubricant contamination is common. Third, the ±0.002mm machining precision ensures perfect alignment with drill shafts and pivot points, preventing misalignment-induced vibration and component damage. Likewise, this stabilizes drill operation and improves overall equipment lifespan.
Fourth, the anti-corrosion bronze alloy resists rust and chemical erosion from mining slurry, passing 600-hour salt spray tests with no degradation. Above all, this ensures reliability in coastal or underground mines with high humidity. Fifth, the wide temperature adaptability (-40°C~120°C) ensures consistent performance in freezing high-altitude mines and hot drill hydraulic system environments. On top of that, the shock-absorbing bronze structure dampens 30G vibration from drill operation, protecting adjacent components from impact damage.
Unlike ordinary industrial bushings, this model is engineered for Hydraulic Rock Drills’ dynamic working conditions. To elaborate, the tungsten carbide insert targets extreme wear, while the self-lubricating design adapts to mining maintenance constraints. Thus, it outperforms generic bushings in service life by 170%, significantly reducing operational costs.
Our manufacturing team uses precision CNC machining + tungsten carbide brazing technology for the bushing. Furthermore, each unit undergoes hardness testing (HRC 62-65) and dimensional verification (±0.002mm). Additionally, the bushing undergoes 500,000-cycle friction trials to ensure no performance degradation.
Notably, it operates stably in temperatures from -40°C (Arctic mining regions) to 120°C (drill mechanical systems). Moreover, the tungsten carbide insert endures 8,000-hour friction trials without excessive wear. In addition, the self-lubricating grooves maintain functionality for 12+ months in typical mining conditions.
The bushing’s press-fit installation design integrates seamlessly with mainstream Hydraulic Rock Drill pivot and shaft assemblies. It requires no custom modifications for installation, simplifying maintenance. As a result, maintenance teams can complete replacement in 25 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform hardness tests, precision inspections, wear resistance trials and corrosion verification. Importantly, it complies with ISO 3547 international bearing and bushing standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces bushing-related failure rates by 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only reduces friction and vibration for drill components but also extends the service life of drill pivot and shaft assemblies by 90%. Overall, Bushing 6060704114 delivers cost-effective, high-performance results for long-term mining operations. Beyond that, it minimizes downtime caused by bushing failure, maximizing operational efficiency and project profitability.
