Bearing material – five advantages of bearing steel

With the needs of society, more and more materials are used for bearings, and bearing steel will be used, such as steel ball, steel ring and so on. Now, China has made some breakthroughs in high-end bearing steel, which can be self-sufficient and export, which is of some help to China’s high-end bearing equipment. But many people still don’t know what are the advantages of bearing steel?


Bearing material – five advantages of bearing steel:


1、 Contact fatigue strength


Under the action of periodic load, the contact surface of linear bearing is prone to fatigue damage, that is, cracking and peeling, which is an important damage situation of linear bearing. Therefore, in order to improve the service life of linear bearing, bearing steel must have high contact fatigue strength.


2、 Wear resistance


During the task of linear bearing, not only rolling friction but also sliding friction will occur between the ferrule, rolling element and cage, so that the parts of linear bearing will be worn all the time. In order to increase the wear of linear bearing parts, maintain the accuracy and stability of linear bearing and extend the service life, bearing steel should have good wear resistance.


3、 Hardness


Hardness is one of the important qualities of linear bearing, which has an indirect impact on contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel in service should reach HRC61 ~ 65, which enables the linear bearing to achieve high contact fatigue strength and wear resistance.


4、 Antirust performance


In order to avoid corrosion and rust of linear bearing parts and finished products in the process of processing, storage and application, it is required that the bearing steel should have good antirust performance.


5、 Processing performance


In the consumption process of linear bearing parts, there are many cold and hot processing procedures. In order to meet the requirements of small quantity, high efficiency and high quality, bearing steel should have good proc
