Product Description

Ceramic bushings are made of a ceramic inner sleeve and a forged steel outer shell. The service life of the ceramic liner is about 4000 to 10000 hours, which is much longer than that of the bi-metal liner. The ceramic lining has the characteristics of wear resistance, erosion resistance, high pressure resistance, high hardness and high strength. Zirconia and alumina types are common types of ceramic sleeves. Compared with the alumina type, the zirconia type liner has better toughness and longer service life, and the piston wear and lubrication water consumption can also be reduced.
