Zirconia ceramic ball ZrO2

Product overview: Yttrium stabilized zirconia beads, because the zirconia content of this type of zirconia beads is approximately 95%, it is often called "95 zirconia" or "pure zirconia beads". It uses rare earth yttrium oxide as a stabilizer, and uses high whiteness and high fineness raw materials to ensure that the materials are not polluted.

Size: 0.4mm~63.5mm, non-standard can be customized.

Features: Zirconia balls have the characteristics of high strength, high toughness, good wear resistance, high temperature resistance and corrosion resistance, high rigidity, non-magnetic conductivity, and electrical insulation at room temperature. Zirconia ceramic balls have almost no change in strength and hardness at 600°C, and the thermal expansion rate is close to the thermal expansion rate of metals, so they can be used in conjunction with metals.

Uses: High-precision zirconia ceramic balls are mainly used in valve balls, full ceramic bearings, measuring balls, track balls, and fine grinding balls. An ideal material to replace steel balls.

High Purity Alumina Ceramic Ball Al2O3

Alumina content ≥ 99.5%, pale yellow in color.

Size: 1.588mm~63.5mm, non-standard can be customized.

Compared with steel balls, the main advantages of alumina ceramic balls are: 50% lighter than steel balls, which reduces the centrifugal force, rolling and wear of the channel caused by the accelerated operation of the bearing; small friction coefficient, good rotation flexibility; high temperature resistance, The service temperature can reach 1850°C; oil-free self-lubrication; more chemical corrosion resistance than steel; no metal pollution; non-magnetic; electrical insulation;

Uses: Suitable for pumps, valves, flow meters, ceramic bearings, mechanical valves, chemical machinery, medical equipment, synthetic fiber manufacturing equipment, optical film equipment, various heat treatment furnaces, vacuum equipment and other harsh environments. The toughness of alumina ceramics is relatively low. Compared with silicon nitride balls, alumina is more suitable for applications with lower cost requirements.

Silicon nitride ceramic ball Si3N4

Size: 0.4~80mm

Product overview: Silicon nitride ceramics are precision ceramics sintered at high temperature in a non-oxidizing environment. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, and can be used in seawater for a long time. And has the good performance of electricity and magnetism. At 800°C, the strength and hardness are almost unchanged. Its density is 3.20g/cm3, and its weight is almost 1/3 of that of bearing steel. When rotating, the centrifugal force is small, and high-speed operation can be realized. It also has self-lubricating properties, it can be used in non-lubricating media and highly polluted environments, and becomes the best material for ceramic bearings and hybrid ceramic bearings.

Uses: Silicon nitride ceramic balls can be used in high-speed bearings, precision bearings, vacuum bearings, high/low temperature bearings, non-magnetic bearings, precision ball screws, and can also be used as valve balls in chemical pumps, high-temperature pumps, and metering pumps. ball etc.

Silicon Carbide Ceramic Balls SiC

Size: 2-20mm

Silicon carbide ceramics not only have excellent mechanical properties at room temperature, such as high flexural strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance denaturation, etc.) are known among ceramic materials. And it has been widely used in petroleum, chemical industry, microelectronics, automobile, aerospace, papermaking, laser, mining and atomic energy and other industrial fields. The hardness of silicon carbide is quite high, second only to several superhard materials.

Uses: high-speed/ultra-high-speed bearings, high-precision bearings, vacuum bearings, high/low temperature bearings, non-magnetic bearings, high-precision ball screws; they can also be used as valve balls and measuring balls in chemical pumps, high-temperature pumps, and metering pumps .
