Silicon carbide ceramic bearings 623-629 are resistant to high temperature, corrosion, and magneto electric insulation

Ceramic bearings
Ceramic bearings, as an important mechanical component, are at the forefront of the new materials world due to their excellent performance that metal bearings cannot match, such as high temperature resistance and super strength
advantage
Firstly, due to the fact that ceramics are almost resistant to corrosion, ceramic rolling bearings are suitable for operation under harsh conditions filled with corrosive media.
Secondly, 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.
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 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 accuracy.
The main purpose of folding and editing this paragraph is
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.
