The heat treatment process of the working surface of the wheel body adopts the overall heating and local quenching process. After the working surface is quenched, the wear resistance of the product is improved and the product life is long.
The assembly is assembled by a dust-free assembly line, vacuumed and refueled after the air tightness test, and subjected to a 100% running-in test, and the product quality is stable.
