High-Temperature Resistant NBR Rubber Gasket for Hydraulic Rock Drills Engineered for extreme underground mining conditions, this gasket ensures reliable sealing in high-vibration hydraulic rock drill applications. Constructed from Nitrile Butadiene Rubber (NBR) with a zinc-plated steel reinforcement ring, it withstands continuous dynamic loads up to 25 bar while resisting oil and abrasion in harsh environments .
Technical Specifications & Design The gasket features a 60 mm inner diameter (ISO 3601 tolerance) and 85 mm outer diameter, designed for secure mounting in hydraulic cylinder assemblies and drill rig components. Its Shore A 70 hardness provides optimal balance between flexibility and structural integrity, reducing the risk of extrusion under high pressure . The zinc-plated steel ring enhances dimensional stability, ensuring consistent performance even in repetitive impact scenarios.
Performance Advantages
Vibration Resistance: Textured surface design minimizes slippage during high-frequency oscillations, maintaining seal integrity in dynamic systems.
Temperature Stability: Operates reliably from -30°C to +100°C, suitable for both cold climates and high-heat drilling environments .
Longevity: NBR rubber compound and steel reinforcement extend service life by 20% compared to standard non-reinforced gaskets, reducing downtime in critical mining operations.
Applications
Underground Mining: Critical for sealing hydraulic connections in rock drills used in tunnel boring and ore extraction.
Heavy Machinery: Used in excavators and loaders to prevent fluid leaks in high-pressure hydraulic systems.
Industrial Hydraulics: Supports presses and material handling equipment, ensuring precision in repetitive motion tasks.
