Sliding Block TA150013 is a critical structural guide component exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground hard rock mines, high-altitude quarries, tunnel construction sites and vibration-intensive drilling areas.
These settings pose unique challenges for sliding blocks: frequent friction with drill rails, heavy impact loads, abrasive rock dust, and temperature swings. These issues often cause block wear, deformation, or jamming, leading to drill feed failure and costly downtime. Yet, Sliding Block TA150013 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its 42CrMo alloy steel base + tungsten carbide coating achieves HRC 62-65 surface hardness. This eliminates rapid wear from friction with drill rails and extends service life by 140% compared to standard steel blocks. Second, the ±0.01mm dimensional precision ensures perfect fit with drill guide rails. Consequently, it avoids jamming during feed movement and maintains stable drill positioning. Third, the self-lubricating graphite insert reduces friction coefficient by 50%. Likewise, this minimizes heat buildup and component damage during continuous operation.
Fourth, the reinforced structural design withstands 500N impact loads from drill vibration and rock collision. Above all, this prevents block deformation or cracking, ensuring uninterrupted guide function. Fifth, the wide temperature adaptability (-30°C~120°C) ensures reliable performance in cold high-altitude mines and hot underground drilling environments. On top of that, the anti-corrosion coating resists rust and chemical erosion from mining slurry, enhancing durability in humid sites.
Unlike ordinary sliding blocks, this model is engineered for Hydraulic Rock Drills’ dynamic working conditions. To elaborate, the tungsten carbide coating balances hardness and toughness, while the self-lubricating design reduces maintenance needs. Thus, it outperforms generic blocks in service life by 150%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision CNC machining + plasma spraying technology for the tungsten carbide coating. Furthermore, each unit undergoes hardness testing (HRC 62-65) and dimensional verification. Additionally, the block undergoes 100,000-cycle sliding trials to ensure no wear exceeding 0.05mm.
Notably, it adapts to extreme temperatures from -30°C (high-altitude cold regions) to 120°C (high-load drill systems). Moreover, it passes 300-hour salt spray tests with no coating peeling or rust. In addition, it endures 5,000-cycle impact trials without deformation.
The sliding block’s bolt-on mounting design integrates seamlessly with mainstream Hydraulic Rock Drill feed systems. It requires no modifications to existing rails or brackets. As a result, maintenance teams can complete replacement in 20 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 impact resistance verification. Importantly, it complies with ISO 898-1 international alloy steel component standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces sliding block-related failure rates by 93%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 56%.
It not only ensures stable drill feed movement but also extends the service life of drill guide systems by 85%. Overall, Sliding Block TA150013 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by block failure, maximizing operational efficiency and project profitability.
