Advantages of ceramic bearings:

Firstly, due to the higher elastic modulus of ceramics compared to steel, they are less prone to deformation under stress, which is beneficial for improving working speed and achieving higher precision.

Secondly, due to the fact that ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operation under harsh conditions filled with corrosive media.

Thirdly, ceramics are less affected by thermal expansion and contraction than steel, so when the clearance between bearings is constant, they can allow bearings to work in environments with significant temperature differences.

Fourthly, due to the lower density and lighter weight of ceramic rolling balls compared to steel, the centrifugal effect on the outer ring during rotation can be reduced by 40%, thereby greatly extending their service life.

Main application areas

Ceramic bearings have characteristics such as high temperature resistance, cold resistance, wear resistance, corrosion resistance, resistance to magnetic and electrical insulation, oil-free self-lubricating, and high speed. It can be used in extremely harsh environments and special working conditions, and can be widely applied in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textiles, pumps, medical equipment, scientific research, and national defense and military fields. It is a high-tech product for the application of new materials. The rings and rolling elements of ceramic bearings are made of all ceramic materials, including zirconia (ZrO2), silicon nitride (Si3N4), and silicon carbide (Sic). The retainer is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thereby expanding the application range of ceramic bearings.
