CNC lathe machined precision zirconia ceramic ring
Description:
Zirconia ceramic has the advantages of super hardness, high wear-resisting,good corrosion resistance and electric insulation,resistant acid-base,high intensity,thermostable,high temperature tolerance,good insulation,high strength,precision process,high mechanical strength,good chemical stability.
Today bearing bushes for exhaust flaps work without displaying any signs of wear at operating temperatures reaching 500 °C, i.e. in environments where conventional materials fail or demonstrate a significantly shorter service life. The outstanding thermal properties of zirconium oxide ceramic material combined with our expertise in precision components result in the perfect solution for exhaust flap bearings.
