High-Performance O-ring for Hydraulic Rock Drills This O-ring is engineered to provide reliable sealing in hydraulic rock drill systems, preventing fluid leakage in high-pressure and high-temperature environments typical in mining operations. Constructed from FKM rubber, it offers exceptional resistance to hydraulic fluids, extreme temperatures, and mechanical wear, ensuring long-term performance in critical components like valves, cylinders, and fluid lines.
Key Performance Attributes
Material & Durability:
FKM rubber (fluorocarbon elastomer) provides superior resistance to synthetic hydraulic fluids, mineral oils, and water-glycol mixtures, maintaining elasticity even after prolonged exposure to temperatures up to 200°C. Its 70 Shore A hardness balances flexibility for tight sealing with resistance to extrusion under 30MPa pressure, a critical feature in high-vibration drill operations .
The molded, splice-free design eliminates weak points, reducing the risk of tearing or failure. This construction supports a service life of 90,000+ cycles, outperforming standard elastomers in durability tests .
Sealing & Precision:
Compliant with ISO 3601-1 size tolerances, the O-ring ensures consistent fit in standard grooves, creating a bubble-tight seal (ISO 5208 Class A) across its operating range. This precision minimizes pressure loss in hydraulic circuits, enhancing overall drill efficiency .
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. It integrates seamlessly with existing hydraulic rock drill assemblies, simplifying replacement during maintenance .
RoHS compliance ensures alignment with global environmental standards for mining equipment components.
Applications
Hydraulic Rock Drills: Seals valve spools, cylinder ports, and high-pressure fluid line connections.
Mining Equipment: Compatible with tunneling machines, quarry drills, and exploration rigs requiring high-performance hydraulic seals.
