High Wear Resistance Ceramic Guide Pulley for Textile Machinery

Surface finish: Ra 0.02 ??m, the lower the value, the less likely it is to damage the yarn; Hardness: Alumina often reaches HV 1800~2100; Density and porosity: Dense ceramics (>95% density) have better wear resistance; High temperature resistance: Long-term usable temperature is 800~1200??C (alumina); Chemical resistance: Resistant to acids, alkalis, and corrosion from textile oils, and does not react with fibers.
