The Joint Torique (Part No. 86221702) is a critical sealing and connection component designed specifically for hydraulic rock drills — core equipment in mining, quarrying, and underground construction projects. Unlike generic joint components, engineers design this part to meet the extreme operational demands of hydraulic rock drills, including high-pressure fluid transfer, constant vibration, and exposure to abrasive rock debris, dust, and moisture. It delivers reliable torque transmission and leak-proof performance in these harsh environments, directly solving the common pain points of hydraulic system failures, fluid leaks, and unplanned downtime that plague mining operations.
This joint torique part plays a dual, non-negotiable role in hydraulic rock drill assemblies. First, it acts as a high-strength connection hub that links hydraulic lines to critical drill components, such as the drill bit, piston, and control valve. This connection ensures efficient and consistent transmission of hydraulic pressure, essential for maintaining the drill’s impact force and drilling speed. Second, it serves as a robust sealing element that prevents hydraulic fluid leaks — a critical feature, as leaks not only waste costly hydraulic oil but also pose safety hazards and accelerate premature wear of other drill parts.
For mining and construction operators, these functions translate to tangible, bottom-line benefits. The leak-proof design reduces fluid consumption and maintenance costs, while the vibration-resistant construction minimizes part fatigue and extends service intervals. Additionally, precise engineering ensures a perfect fit, eliminating the need for on-site modifications and cutting down on installation time. These advantages combine to boost overall operational efficiency, reduce equipment downtime, and maximize the productivity of hydraulic rock drill fleets.
Engineers design the Part No. 86221702 Joint Torique to fit a wide range of hydraulic rock drill models, including both surface and underground drill rigs commonly used in open-pit mining, underground tunneling, quarrying, and foundation drilling projects. It serves as a direct, drop-in replacement for worn or damaged joints, ensuring seamless integration with existing drill setups without custom machining or adjustments. Whether teams use it in a small-scale quarry drill or a large, heavy-duty mining rig, this joint torique maintains consistent performance across all application scenarios. It also works with a variety of hydraulic fluid types, including mineral-based oils and synthetic hydraulic fluids, making it a versatile solution for diverse operational needs.
Manufacturers use high-strength, corrosion-resistant alloy materials to produce this joint torique, which meets strict international industrial standards for hydraulic equipment components, including ISO 6020/2 and SAE J518 specifications. The production process includes precision machining to ensure tight tolerances — a critical factor for maintaining leak-proof seals under high pressure. Every unit undergoes rigorous quality testing: technicians conduct pressure testing up to 350 bar (5000 psi) to verify leak resistance, run vibration testing to simulate long-term drill operation, and perform corrosion testing to ensure durability in humid or chemically harsh mining environments.
Furthermore, the part features a specialized protective coating that guards against rust, abrasion, and chemical degradation from hydraulic fluids and rock dust. This coating extends the part’s service life by up to 50% compared to uncoated alternatives, reducing the frequency of part replacements and lowering long-term maintenance costs. A 12-month warranty backs the part for industrial use, making the Joint Torique 86221702 a reliable, cost-effective choice for hydraulic rock drill maintenance and repair.
Installing the Joint Torique 86221702 is straightforward and requires no specialized tools, making it ideal for on-site maintenance teams. Prior to installation, users should clean the connection surface of the hydraulic drill to remove any debris or old sealant, ensuring a tight, secure fit. Teams should torque the part to the manufacturer’s recommended specification (typically 25–30 N·m) to avoid over-tightening, which can damage the sealing surface. For optimal performance, inspect the joint torique every 500 hours of drill operation, checking for signs of wear, corrosion, or leaks. Regular inspections help identify potential issues early, preventing costly breakdowns during critical mining operations.
