The main purpose of ceramic rail axles is to reduce the maintenance costs and improve the operational efficiency of track transportation systems. Due to the excellent wear resistance of ceramic materials, the use of ceramic rail axles can reduce track wear, extend the service life of tracks and wheels, thereby reducing maintenance costs. In addition, ceramic rail axles can also reduce train noise and vibration, improving passenger comfort.

Ceramic rail axles are commonly used on the main lines of high-speed trains and subway systems, especially under high load and high-speed conditions. They are also widely used in special environments such as underground tunnels, bridges, and coastal areas, where ceramic rail axles have stronger resistance to corrosion and wear.
