How high can the bearing operating temperature be accepted?
How high the working temperature can the general bearing withstand, usually the general material bearing use temperature is better than 120 degrees Celsius, otherwise it will affect the service life of the bearing. Bearings made of high temperature metal materials can generally be used at temperatures ranging from 200 to 300 degrees Celsius. The operating temperature of ceramic bearings can reach 450 degrees Celsius.
Therefore, in fact, the temperature of the bearing is not particularly high, but the increase in the temperature of the shaft bearing is avoided by various methods.
Where the use of bearing products, its performance, precision, life, reliability, etc. are closely related to the bearing, in some high-tech products, the bearing has been regarded as the core component. Today we will use pictures to show the development and change of bearings, working principles, types and applications.
The early form of linear motion bearings consisted of placing a row of wooden rods under a row of crowbars. Modern linear motion bearings use the same working principle, except that balls are sometimes used instead of rollers. A simpler rotating bearing is a bushing bearing, which is simply a bushing sandwiched between the wheel and the axle. This design was then replaced by rolling bearings, which replaced the original bushing with many cylindrical rollers, each of which resembled a separate wheel.
