High-Performance O-Ring for Hydraulic Rock Drills This O-ring is engineered to deliver exceptional sealing performance in high-pressure, high-temperature hydraulic rock drill systems, preventing fluid leakage in demanding mining environments. Constructed from FKM rubber, it combines superior chemical resistance with robust thermal stability, making it ideal for critical components such as high-pressure valves, pumps, and cylinder ports.
Key Performance Attributes
Material & Durability:
FKM rubber (fluorocarbon elastomer) offers outstanding resistance to degradation from synthetic hydraulic fluids, mineral oils, and water-glycol mixtures, maintaining elasticity even after prolonged exposure to extreme temperatures. Its 73 Shore A hardness ensures optimal compression in grooves, creating a secure seal without extrusion under 35MPa pressure—critical for withstanding pressure surges in rock drill operations .
The molded, splice-free design eliminates weak points, reducing the risk of failure during installation or vibration-induced movement. This construction extends service life to 100,000+ cycles, outperforming standard elastomers in long-term reliability tests .
Sealing & Precision:
Compliant with ISO 3601-1 size tolerances, the O-ring ensures consistent fit in AS568 standard grooves, validated through 15,000-cycle pressure testing (ISO 18797) with zero measurable leakage. This precision minimizes pressure loss in critical hydraulic circuits, enhancing overall drill efficiency and reducing maintenance downtime .
Operational Compatibility:
The -20°C to +200°C temperature range makes it suitable for both cold underground mines and high-heat zones near drill motors, maintaining flexibility across the entire spectrum. It integrates seamlessly with existing hydraulic rock drill assemblies, supporting quick and easy replacement during maintenance .
RoHS compliance ensures alignment with global environmental standards for mining equipment components, meeting regulatory requirements in key markets.
Applications
Hydraulic Rock Drills: Seals high-pressure valves, pump housings, and cylinder connections in systems using synthetic or mineral oil-based hydraulic fluids.
Mining Equipment: Compatible with tunneling machines, quarry drills, and exploration rigs requiring high-performance hydraulic seals.
