803268811 XCMG GR2605 motor grader hose assembly

Core Product Advantages

Specifically designed and developed for the XCMG GR2605 motor grader, this product precisely matches the model’s 194kW power output and the high-pressure operating conditions of the hydraulic system, perfectly adapting to the wear-resistant, impact-resistant, and vibration-resistant requirements of harsh environments such as mines and infrastructure projects. It adopts a multi-layer high-density steel wire winding reinforcement design, improving pressure resistance by 80% compared to traditional braided structures. With a rated working pressure of 40MPa and a 1.5 times safety margin, it effectively resists hydraulic system pressure pulses and high-frequency impact loads, eliminating the risk of pipe bulging and bursting. The inner rubber layer uses oil-resistant and anti-aging special synthetic rubber, with a swelling rate of ≤2% after 72 hours of immersion at 70℃. It can withstand long-term corrosion from various media such as petroleum-based hydraulic oil, polyethylene glycol-based hydraulic oil, and water-oil emulsions. The outer rubber layer uses a high-temperature resistant, ozone-resistant, and wear-resistant formula with a black wear-resistant surface, providing a service life of over 8 years in harsh outdoor environments, suitable for alternating high and low temperatures and complex terrain friction scenarios. The connector utilizes an integrated cold-pressing molding process, ensuring a tight fit between the metal sleeve and the hose. The sealing pressure reaches 1.5 times the working pressure, completely resolving the slippage and leakage problems of traditional connection methods. The standardized interface strictly complies with XCMG’s original factory installation specifications, allowing for rapid integration without additional modifications. It offers convenient maintenance and strong compatibility, significantly reducing equipment downtime losses and meeting XCMG’s high reliability standards for hydraulic components.

Key Technical Parameters

Application scenarios

Suitable for soil leveling, slope trimming, and heavy-duty operations in mining, road construction, farmland improvement and other projects, especially suitable for the harsh requirements of high-frequency oscillation, frequent pipeline bending, severe vibration and multi-media working conditions. As the “power vessels” of the hydraulic system, it provides stable and leak-free power transmission to key hydraulic components such as the grader’s blade drive, steering system, and braking circuit. This effectively prevents system failures due to pipeline malfunctions, significantly improves operational continuity and safety, and helps the machine maintain efficient and stable operation under complex and harsh conditions. It is the preferred original equipment manufacturer (OEM) part for the maintenance and replacement of the XCMG GR2605 grader’s hydraulic system.
