Custom full ceramic bearings made from Zirconia, Silicon Nitride, or Alumina. Lightweight, corrosion-resistant, non-magnetic, high-speed, and wear-resistant for pumps, medical, semiconductor, chemical, and precision equipment applications. 
Full Ceramic Bearings are manufactured entirely from high-performance ceramic materials, including inner ring, outer ring, and rolling elements. Common material options include Zirconia (ZrO2), Silicon Nitride (Si3N4), and Alumina (Al2O3). These bearings are designed for demanding environments where traditional steel bearings may fail due to corrosion, electrical conductivity, magnetic interference, lubrication limitations, or excessive wear.
Compared with metal bearings, full ceramic bearings provide significant advantages in chemical resistance, low density, electrical insulation, non-magnetic behavior, and long service life under special operating conditions. They are ideal for industries such as chemical processing, semiconductor equipment, medical devices, food machinery, laboratory systems, vacuum equipment, marine equipment, and high-speed machinery.
At CERAMPRO, we offer custom full ceramic bearings with flexible dimensions, material selection, cage options, tolerance control, and surface finishing according to your application requirements.
Full ceramic bearings can operate in environments exposed to water, salt spray, acids, alkalis, and chemicals where steel bearings are prone to rust and corrosion.
Ceramic materials are naturally non-magnetic and non-conductive, making them suitable for precision instruments, medical systems, semiconductor equipment, and electrical insulation applications.
Ceramic materials are lighter than steel, which helps reduce rotational inertia and improve high-speed response in certain dynamic systems.
Full ceramic bearings provide excellent surface hardness, helping reduce wear and maintain dimensional stability in abrasive and high-precision applications.
Ceramic bearings can withstand elevated temperatures better than many metal bearings and can operate in environments where conventional lubrication becomes difficult.
In some special operating conditions, full ceramic bearings can work with minimal lubrication or even dry-running conditions, depending on load and speed.
Because ceramic materials resist oxidation and corrosion, they are widely used in clean systems requiring reduced contamination risk.
Zirconia full ceramic bearings are known for their high toughness, good strength, smooth surface finish, and balanced overall performance. They are commonly used in medical devices, food equipment, chemical pumps, and precision machinery.
Advantages:
Silicon nitride bearings are preferred for high-speed, high-load, and thermal shock-sensitive applications due to their outstanding mechanical performance.
Advantages:
Alumina full ceramic bearings offer excellent electrical insulation, chemical stability, and cost-effectiveness for many general applications.
Advantages:
A standard full ceramic bearing may include:
We can provide:
Compared with conventional stainless steel or chrome steel bearings, full ceramic bearings offer:
However, full ceramic bearings should be selected carefully according to load, speed, impact conditions, assembly accuracy, and operating environment. Our engineering team can help recommend the right material and design for your application.
Full ceramic bearings are widely used in:

What we offer:
A full ceramic bearing is a bearing in which the rings and balls are made entirely from ceramic materials rather than steel.
Common materials include Zirconia (ZrO2), Silicon Nitride (Si3N4), and Alumina (Al2O3).
They are better for special applications requiring corrosion resistance, insulation, non-magnetic performance, lightweight operation, or chemical stability. The best choice depends on the actual working condition.
In some applications, yes. However, whether dry-running is suitable depends on load, speed, and operating conditions.
Yes. We support custom dimensions, structures, materials, and tolerance requirements based on drawings or samples.
