Product details

Science and technology are constantly advancing. This leads to more stringent requirements for advanced ceramics to satisfy your higher requirements. The unique properties of zirconia ceramics offer us many advantages in comparison with traditional metals and plastics. Their advantages in higher temperature range, durable life and the reliability enable us to confidently state that zirconia can be used as an all-round material in all sectors of the industry, especially for various sleeves and bushing use.


Our zirconia sleeves and bushings have the advantages of super hardness, high wear-resisting, good corrosion resistance, high strength, high mechanical strength, good chemical stability, self-lubricating, and fine polishing surface .so they widely used for shaft protection and insulation. Due to the high cost of zirconia material, the hollow sleeves and bushing design can save the material cost greatly. Thanks to its similar thermal expansion coefficient with steel, so it can be assembly with steel shaft/pin directly. This economic compound fabrication makes zirconia sleeves and bushings can be used widely regardless of its high cost.
