Dusty Ring PT08023500 is a critical dust-proof sealing accessory exclusively designed for Hydraulic Rock Drills. It excels in ultra-dusty mining environments—for instance, open-pit quarries, underground tunneling sites, and dry rock drilling areas with high particle contamination.
These settings pose severe challenges for drill dust seals: heavy rock dust infiltration, hydraulic oil erosion, intense vibration (up to 25G), temperature fluctuations, and friction with moving drill rods. These issues often cause dusty ring cracking, wear, dust leakage, or seal detachment, leading to drill internal component abrasion and costly downtime. Yet, Dusty Ring PT08023500 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its NBR rubber + reinforced polyester fiber core achieves IP66 dustproof certification, blocking 99.9% of rock dust and fine particles from entering drill cylinders. This eliminates internal component wear and extends drill service life by 140% compared to standard dust rings. Second, the Shore A 70 hardness rubber balances flexibility and durability, ensuring tight contact with drill rods while resisting friction damage. Consequently, it reduces seal replacement frequency by 30%. Third, the oil-resistant NBR formulation resists erosion from hydraulic oil and lubricants, complying with ISO 696 standards. Likewise, this prevents seal swelling or hardening in oil-contaminated environments.
Fourth, the vibration-dampening fiber core design withstands 25G vibration from drill operation, avoiding seal detachment or deformation. Above all, this ensures continuous dustproof protection even during high-intensity drilling. Fifth, the wide temperature adaptability (-35°C~110°C) ensures reliable performance in freezing high-altitude mines and hot underground drill systems. On top of that, the precision-molded cross-section matches drill cylinder/rod dimensions perfectly, providing a leak-proof seal without manual adjustment.
Unlike ordinary industrial dust rings, this model is engineered for Hydraulic Rock Drills’ dusty working conditions. To elaborate, the reinforced fiber core targets mining vibration, while the IP66 dustproof rating addresses heavy particle contamination—features tailored to drill operational needs. Thus, it outperforms generic dust rings in service life by 150%, significantly reducing maintenance costs.
Our manufacturing team uses precision compression molding + fiber reinforcement technology for the dusty ring. Furthermore, each unit undergoes IP66 dustproof testing and hardness verification (Shore A 70). Additionally, the ring undergoes 100,000-cycle rod friction trials to ensure no performance degradation.
Notably, it operates stably in temperatures from -35°C (high-altitude cold mines) to 110°C (drill hydraulic cylinder systems). Moreover, it passes 400-hour oil immersion tests with no swelling or seal failure. In addition, the NBR surface endures 300-hour abrasion trials without excessive wear.
The dusty ring’s snap-fit installation design integrates seamlessly with mainstream Hydraulic Rock Drill cylinders/rods. It requires no tools for installation or removal, simplifying maintenance. As a result, maintenance teams can complete replacement in 5 minutes.
Our quality team conducts strict ISO 9001 verification for every unit. We perform dustproof tests, hardness inspections, vibration resistance trials and oil resistance verification. Importantly, it complies with ISO 3601 international hydraulic seal standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces dusty ring-related failure rates by 93%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 55%.
It not only ensures IP66 dustproof sealing for drill components but also extends the service life of drill cylinders/rods by 85%. Overall, Dusty Ring PT08023500 delivers cost-effective, dust-proof protection for long-term mining operations. Beyond that, it minimizes downtime caused by seal failure, maximizing operational efficiency and project profitability.
