Product Description

High Speed KHRD Deep groove ball  bearing 697 Si3n4 Ceramic Bearing 
 

Ceramic Bearing
 

      The performance comparison of ordinary bearing steel AISI52100 (GCr15), stainless steel AISI440 (9Cr18), silicon nitride (Si3N4) and zirconia (ZrO2) four kinds of bearing materials, ceramic bearing as an important mechanical basic part, because of its metal bearing Unparalleled excellent performance, high temperature resistance, super strength, etc. dominate the world of new materials. In the past ten years, it has been widely used in various fields of national economy and people's livelihood.

Advantages

First, because ceramics are hardly afraid of corrosion, ceramic rolling bearings are suitable for operation under harsh conditions full of corrosive media.
Second, because the density of the ceramic rolling ball is lower than that of steel, the weight is much lighter, so the centrifugal effect of the outer ring during rotation can be reduced by 40%, and the service life is greatly extended.
Third, ceramics are less affected by thermal expansion and contraction than steel, so when the bearing gap is constant, the bearing can be allowed to work in an environment where the temperature difference changes more drastically.
Fourth, since the elastic modulus of ceramic is higher than that of steel, it is not easy to deform when subjected to force, so it is beneficial to increase the working speed and achieve higher accuracy.

The main purpose

Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubricating, and high speed. It can be used in extremely harsh environments and special working conditions. It can be widely used in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research, national defense  fields. High-tech products for the application of new materials.
