Abstract: Abstract In recent times, there has been a growing interest in examining the reliability and service life of electro-hydraulic servo mechanisms under natural storage conditions. Notably, extensive research has been conducted on the topic of prolonging the storage life of these mechanisms. However, due to the diverse components involved in electro-hydraulic servo mechanisms, determining accurate influencing factors through whole-machine accelerated storage methods has proven to be difficult. As a result, individual component accelerated storage methods have been employed in the past to estimate the storage life of the entire machine. Nonetheless, this approach lacks an understanding and verification of the actual lifespan and performance changes under natural storage conditions. This paper aims to explore the performance changes of electro-hydraulic servo mechanisms under natural storage conditions. A divide-and-conquer approach is employed to analyze the hydraulic circuit and control circuit’s performance changes separately. The research investigates each component in corresponding circuits to identify how its performance changes under different natural storage times and suggests appropriate measures to extend their service life. Actual sample test results demonstrate that the proposed engineering measures can effectively prolong the period during which electro-hydraulic servo structures can be utilized under natural storage conditions.
