High-Precision Nitrile Rubber Seal Kit for Hydraulic Rock Drills Engineered for extreme underground mining conditions, this seal kit ensures reliable performance in high-vibration hydraulic rock drill systems. Constructed with ISO 3601-1 compliant nitrile rubber (NBR) O-rings and polyurethane backup rings, it withstands continuous dynamic loads while resisting abrasion and corrosion in harsh environments .
Technical Specifications & Design The seal kit includes four O-rings (38 mm inner diameter, 55 mm outer diameter) and two polyurethane backup rings, designed to maintain pressure integrity in hydraulic cylinders. The nitrile rubber components offer a temperature range of -40°C to +120°C and a maximum working pressure of 350 MPa, ensuring compatibility with high-pressure hydraulic systems . The 3.5 mm seal thickness and 95 Shore A hardness provide optimal resilience against extrusion and wear .
