A long-life and high-stability grease is developed to meet the demand of long-life lubrication condition with storage requirement. The physical and chemical properties,biodegradability, bearing life and rheology of the grease are studied. The results show that compared with the commercial grease, long-life and high-stability grease has lower evaporation loss at high temperature and lower oil separation ratio, which shows that it has better volatility and colloidal stability. The wear scar diameter of SRV test is smaller, and the life of wheel bearing and FE9 is longer, indicating that it has better anti-wear performance, lubrication performance and oxidation stability. The cumulative biodegradation rate in 28 days is 1.82%, which is much lower than 29.19% of the commercial grease. The rheological tests show that it has better structural stability. The developed long-life and high-stability grease has excellent comprehensive performance and can be used in the long-life application environment with long-term storage requirements and harsh working conditions.
