Bearing steel performance requirements, common materials of bearing steel
Bearing steel is mainly used to manufacture rolling elements and rings of rolling bearings. Because the bearing should have the characteristics of long life, high precision, low heat generation, high speed, high rigidity, low noise, high wear resistance, etc., the bearing steel is required to hav...Read more -
How to use expansion bolts
The use method and principle of expansion bolts: When using, you must first drill holes of the corresponding size in the fixed body with an electric impact drill (hammer) (this is very important, first ask the size of the bolt when purchasing, and then use the drill of the corresponding size to d...Read more -
The main difference and operation type of annealing and normalizing of bearing production process
Annealing is also called simmering, and the code is Th. It is to heat the steel to Ac1 or Ac3 above (30~50℃), keep it for a period of time, and then slowly cool it (usually with furnace cooling). Normalizing, also known as open flame, code Z, is to heat steel parts above Ac3 or Acm (30~50℃), keep...Read more -

Analysis of pre-deformation and pre-stress of flexible thin-walled bearings
When the flexible bearing of the harmonic reducer is assembled on the elliptical cam of the wave generator, there is a large pre-stress and pre-deformation. Under the actual working load, pre-stress and pre-deformation, the inner and outer ring of the flexible bearing is analyzed, and its deforma...Read more -
How to distinguish bearing accuracy? Bearing tolerance class
The key to bearing tolerance level is to determine the rotation accuracy of the shaft to the supporting point. Level 0: Generally used for bearing systems with a rotation accuracy of more than 10 microns, and the application is very common. For example, the speed regulation mechanism of ordinary ...Read more -
What is a washer？
