High-Pressure Seal for Hydraulic Rock Drills Engineered for extreme mining environments, this seal ensures reliable leak-free performance in hydraulic rock drills and heavy-duty equipment. Constructed from 70 Shore A NBR rubber, it withstands high pressures, vibration, and corrosive conditions, making it ideal for prolonged use in underground mining and quarrying operations.
Technical Specifications & Design The seal adheres to ISO 16232 standards, featuring a 30 mm ID and 42 mm OD with precision-machined lip profiles. Its 2.5 mm contact width provides a 12-15% compression ratio in 4.5 mm deep mounting grooves, ensuring secure sealing under dynamic loads. The chamfered edges facilitate easy installation without damage to the piston or housing.
Performance Advantages
High-Pressure Stability: Withstands up to 30 MPa dynamic pressure, exceeding typical hydraulic system requirements .
Corrosion Resistance: Passes 72-hour salt spray testing (ASTM B117), ensuring longevity in wet or salty environments .
Temperature Compatibility: Maintains structural integrity from -20°C to +100°C, suitable for hydraulic fluids with temperature fluctuations .
Low Friction: Smooth lip surface reduces wear and energy consumption in high-cycle applications.
Applications
Hydraulic Rock Drills: Secures piston assemblies and valve systems in Sandvik/Atlas Copco-compatible equipment.
Mining Machinery: Used in crushers, conveyor systems, and drill rigs requiring high-pressure sealing.
Industrial Hydraulics: Supports presses, excavators, and material handling equipment in harsh environments.
