High-Performance Cup Seal for Hydraulic Rock Drills —— Model RD18U
Key Features & Technical Specs
This cup seal (part number 3115336500) is engineered for critical sealing applications in hydraulic rock drills, specifically designed to withstand high-pressure environments in underground mining and tunnel construction. Constructed from industrial-grade nitrile rubber (NBR), it offers superior resistance to abrasion, oil, and thermal stress, ensuring reliable performance equivalent to OEM standards.
Benefits
Durable Sealing Design
Double-lip configuration (primary and secondary seals) provides bidirectional pressure resistance, preventing hydraulic fluid leakage and external contaminant ingress.
Precision-machined edges with radiused corners (R0.3-R0.5mm) reduce friction and metal-to-metal wear, extending component lifespan by up to 30%.
Rugged Environment Suitability
Tested for compatibility with mineral-based hydraulic oils and synthetic fluids commonly used in mining equipment.
Resistant to ozone, humidity, and particulate matter, making it ideal for harsh underground conditions.
Applications
Hydraulic rock drill maintenance: Direct replacement for worn seals in 冲击机构 (impact mechanisms) and rotary motors.
Mining and tunneling projects: Suitable for hardrock drilling, shaft sinking, and roadway development.
Industrial equipment retrofits: Interchangeable with similar-sized cup seals in heavy machinery hydraulic systems.
