Different Material of Ceramic Bearing Balls

Time : November 11, 2024

Ceramic ball materials:
The main materials of ceramic balls include Zirconia (ZrO2),alumina (Al2O3), silicon nitride (Si3N4) and silicon carbide(SIC). These materials have excellent properties such as high hardness, wear resistance and high temperature resistance, making ceramic balls widely used in many fields.

The main advantages of ceramic balls include the following aspects:

•‌Good fluidity‌: Ceramic balls have excellent fluidity, which can improve production efficiency, reduce energy consumption, and improve product dimensional stability and prevent warping.
•‌‌High precision‌: Ceramic balls can replace metal bearings to improve the stability and precision of equipment.
‌Energy saving and consumption reduction‌: Due to the small specific gravity and light weight of ceramic balls, they can be used in tube mills to save energy and reduce consumption.
‌•‌Good thermal stability‌: Ceramic balls have a high melting point and do not decompose at high temperatures, which can improve the flame retardancy and thermal deformation temperature of products.
•‌‌Good insulation‌: Ceramic balls have high specific resistance and low water absorption, which are suitable for the production of cable insulation materials.
‌•‌Strong corrosion resistance‌: Ceramic balls are mainly composed of aluminum silicate, which can remain stable in various organic solutions and acid and alkali solvents.
•‌‌Oil-free self-lubricating‌: Ceramic balls have oil-free self-lubricating properties, low friction coefficient, suitable for high-speed operation, and long service life.
‌•‌High speed and acceleration capability‌: Ceramic bearings have high speed and acceleration capabilities, long life, wear resistance, low friction temperature rise, minimal lubrication required, low friction loss, good heat resistance, high durability, low torque, non-magnetic and non-conductive, low magnetic permeability‌.

①Silicon Nitride Ceramic Balls (Si₃N₄)

Silicon nitride ceramics have a wide range of applications, including but not limited to high-temperature structural materials, electronic packaging, wear-resistant parts, high-temperature furnaces, aerospace parts, etc. Due to its excellent performance, silicon nitride ceramics are often the preferred material in many applications that need to withstand extreme environments such as high temperature, high speed, and strong corrosive media.

②Zirconia Ceramic Balls(ZrO2)

Zirconia ceramics are widely used in mechanical seals, ball mill media, ceramic bearings, automotive engine parts, paper machine dehydration equipment and other fields due to their excellent performance. In addition, in watchmaking, zirconia ceramics have become an ideal environmentally friendly material due to its insulation, high density, beautiful and durable characteristics.

③Silicon Carbide Ceramic Balls(SIC)

Silicon carbide ceramics are widely used in chemical machinery, energy and environmental protection, semiconductors, metallurgy, national defense and military industries. Specific applications include high-temperature kiln furniture materials, rockets, aircraft, automobile engines and gas turbine components, heat exchange systems of industrial kilns, desulfurization nozzles, magnetic pumps and shielded pump components, etc.

④Alumina Ceramic Balls(Al2O3)

Alumina ceramics are suitable for various harsh working environments and usage scenarios, such as high temperature, high humidity, strong corrosion, etc., and can meet the needs of different industries.
