Product Details

Silicon nitride bearing: with electrical insulation, high-speed rotation, corrosion resistance, no rust, self-lubrication, high temperature resistance, low density characteristics, suitable for. Motor (such as new energy vehicle motor), aviation engine, high-speed machine tools, rail transit, etc.

1, electrical insulation: non-conductive, excellent insulation performance;

2, high speed: ordinary bearing can bear the maximum speed of 30,000 RPM, silicon nitride can reach 400,000 RPM;

3, corrosion resistance: can be resistant to any acid and alkali corrosion except hydrofluoric acid;

4, no rust: can work in the water for a long time, without rust inhibitor;

5, self-lubrication: no need to add any lubricant;

6, high temperature resistance: thermal expansion coefficient of steel 1/3 ~ 1/4, with the temperature change size change is small, suitable for the occasion of large temperature change;

7, low density: 40% of steel ball, small centrifugal force at high speed operation, long life.

Suitable for new energy vehicles, high-speed machine tools, high-speed electric hair dryer, insulation, high-speed and ultra-high-speed, high temperature, corrosion resistance, vacuum, chemical industry and other industries. It is also used in turbine charger bearings, medical and surgical instruments (such as dental drills), food processing equipment and chemical instruments, and superconducting devices, etc.
