ttfi££PUiE$Full ceramic bearing of Si3N4 material ■ , aEfmsjitbBg. bjto?, wmn. Beside having all property of Zr02 full ceramic bearing, Si3N4 full ceramic bearing has property such as light weight, good wearability and high hardness.The full ceramic bearing with Si3N4 material,compared with the full ceramic bearing with Zr02 material, is more applicable to high rotational speed and high load capacity and it can resist higher temperature than that of Zr02. In addition, it has good high temperature strength, mechanical anti-oxidation capacity, high temperature bearing capacity and can resist corrosive gas. Cage material according to different customer service environment requirements of choice, different environmental frame use each are not identical, specific can consult our company professionals. Compare with other types of ceramic materials, full ceramic bearing SiC material is more outstanding in these aspects: higher chemical corrosion resistance, better strength, higher hardness, higher wear resistance, lower frictional properties, and suitable for the highest temperature.
