1 minute to learn about high temperature ball bearings!

Common types of high temperature ball bearings:
High temperature self-aligning ball bearing: between the inner ring of the two raceways and the outer ring of which the raceway is spherical, two rows of steel balls guided by the cage are assembled. Self-aligning ball bearings can bear a large radial load, and can also bear a certain axial load.
high temperature ball bearings with stamped steel cages lubricated with high quality white high temperature grease can be used in temperature environments from -40 to +300°C. It can meet the working conditions within 300 ℃.
High temperature ball bearings are usually produced with ordinary tolerances, and the clearance is much larger than ordinary bearings, so they are usually not suitable for high-speed operation. But it can usually run at 100 rpm for a long time.

High temperature resistant deep groove ball bearing: there is no retainer inside, only rolling elements; it can meet the working conditions of about 300 ℃, and is produced according to ordinary tolerances, and the clearance is much larger than ordinary bearings, so it is usually not suitable for high-speed operation. Speed ​​bearings, usually for long-term operation at speeds up to 200 rpm.
ZYSL high temperature ball bearings can not only work under high temperature and high pressure, but also withstand corrosion caused by high temperature; they also need to have the characteristics of non-magnetic conductivity, wear resistance, long life and high reliability. In addition, high temperature ball bearings are also required to operate under special working conditions such as shock, vibration, tilt, and swing with the drive mechanism, and the working environment and conditions of high temperature ball bearings are quite demanding.

Requirements
During normal operation, high temperature ball bearings should not have abnormal phenomena of sticking and noise. At the same time, high temperature ball bearings need to withstand the influence of vibration, shock and other factors. The materials used in the bearings must be resistant to wear, non-magnetic and corrosion resistance. performance.
material selection
According to the special working conditions of high temperature ball bearings, the material of the ferrule and the ball should have the characteristics of high temperature resistance, corrosion resistance, wear resistance and non-magnetic. It is recommended to use G52# alloy for the ferrule and Si3N4 or cermet for the ball.
Use environment
High temperature ball bearings are widely used in metallurgy, kiln, glass, blast furnace, painting equipment and other high temperature operation machinery.
