■ Introduction:
A zirconia ceramic sleeve is a cylindrical-shaped component made of zirconia ceramic material.The zirconia ceramic sleeve liner commonly used in various applications, including as a bearing or bushing, in valves, pumps, and other machinery. Zirconia ceramic is valued for its high strength, hardness, and wear resistance, making it a popular choice for applications that require durability and longevity. The zirconia ceramic sleeve liner cylinder is often used in high-temperature or corrosive environments, where other materials may not be suitable. The zirconia liner cylinders are also known for their excellent thermal stability and low thermal conductivity. Zirconia ceramic sleeves are becoming increasingly popular in the oil and gas industry, particularly for use in mud pumps.
