All ceramic bearings have many advantages

Advantages for all ceramic bearings
First, because ceramics are virtually unaffected by corrosion, all ceramic bearings are suitable for operation in harsh conditions filled with corrosive media.

Second, because the density of ceramic rolling balls is lower than that of steel, they are much lighter, thus reducing the centrifugal force on the outer ring during rotation by 40%, thereby significantly extending their service life.
Third, ceramics are less affected by thermal expansion and contraction than steel, allowing the all ceramic bearings to operate in environments with significant temperature variations, provided the all ceramic bearings clearance is constant.

Fourth, because ceramics have a higher elastic modulus than steel, they are less prone to deformation under stress, which is beneficial for increasing operating speed and achieving higher precision.
Main uses for all ceramic bearings
All ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication, and high speed.
They can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textile, pumps, medical devices, scientific research and national defense.

The rings and rolling elements of ceramic bearings are made of all-ceramic materials, including zirconium oxide (ZrO2), silicon nitride (Si3N4), and silicon carbide (Sic). The retainer is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconium oxide, silicon nitride, stainless steel or special aviation aluminum.
With continuous advancements in processing technology and improvements in manufacturing processes, the cost of all ceramic bearings has been steadily decreasing. They have expanded beyond limited applications in high-end, precision, and specialized fields. Numerous successful cases, tested through large-scale, long-term use across various industries, have demonstrated the superior advantages of all ceramic bearings and ceramic ball bearings, including maintenance-free operation, long lifespan, high stability, and low cost.
