Ceramic Deep Groove Ball Bearing

Ceramic bearings have characteristics such as high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetoelectric insulation, oil-free self-lubrication, and high rotational speed. It can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textiles, pumps, medical equipment, scientific research, 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, polyether imide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thereby expanding the application range of ceramic bearings.

Application field:

Medical equipment, cryogenic engineering, optical instrument, high-speed machine tools, high-speed motors, printing machinery, food processing machinery.

In the fields of aerospace, navigation, nuclear industry, petroleum, chemical industry, light textile industry, machinery, metallurgy, electricity, food, locomotives, subways, high-speed machine tools, scientific research and national defense military technology, etc., it is necessary to work under special working conditions such as high temperature, high speed, deep cold, flammable, explosive, strong corrosion, vacuum, electrical insulation, non-magnetic, dry friction, etc. The indispensable replacement role of ceramic bearings is gradually recognized by people.

Usage classification:

1) High speed bearing: It has advantages such as cold resistance, low stress elasticity, high pressure resistance, poor thermal conductivity, light self weight, and low friction coefficient, and can be applied in high-speed spindles and other high-precision equipment at 12000 rpm to 75000 rpm;

(2) High temperature bearing: The material itself has high temperature resistance of 1200 ℃ and good self-lubrication. It does not cause expansion due to temperature difference when used between 100 ℃ and 800 ℃. Can be applied in high-temperature equipment such as furnaces, plastics, and steel making;

(3) Corrosion resistant bearings: The material itself has corrosion resistance characteristics and can be applied in fields such as strong acids, strong alkalis, inorganic, organic salts, seawater, etc., such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.

(4) Anti magnetic bearing: Due to its lack of magnetism, it does not absorb dust, which can reduce bearing surface peeling and thus reduce operating noise. Can be used on demagnetization devices. Precision instruments and other fields.

(5) Electric insulated bearings: Due to their high resistivity, they can avoid arc damage to the bearings and can be used in various power equipment that require insulation.

(6) Vacuum bearings: Due to the unique oil-free self-lubricating characteristics of ceramic materials, they can overcome the problem of ordinary bearings being unable to achieve lubrication in ultra-high vacuum environments. Note: The above five types of bearings can be used in high-temperature, high-speed, acid-base, magnetic field, and non insulation environments with the same set of bearings. However, due to different material properties (please refer to the rare earth ceramic material performance table), customers are advised to choose the most suitable ceramic bearing material based on their application situation when selecting products.
