Bearing material Bearing steel features:
First, the contact fatigue strength
Bearing in the cycle under the action of load, the contact surface is very easy to attack fatigue damage, the emergence of spalling peeling, which is an important bearing damage. Therefore, in order to improve the service life of bearings, bearing steel must have a high contact fatigue strength.
Second, wear resistance
Bearing tasks, rings, rolling between the rolling bearing and not only the occurrence of friction, but also the occurrence of sliding friction, so that the bearing parts have been worn. In order to increase the wear of bearing parts, to maintain the accuracy of bearing stability, extended service life, bearing steel should have a good wear resistance.
Third, hardness
Hardness is an important quality of bearing quality, one of the contact fatigue strength, wear resistance, elastic limit has an indirect impact. Bearing steel in the use of the hardness of the individual to reach HRC61 ~ 65, the ability to make the bearing to achieve a higher contact fatigue strength and wear resistance.
Fourth, anti-rust performance
In order to avoid bearing parts and finished products in the processing, storage and use of the process of erosion and rust, bearing steel should have good anti-rust performance.
Fifth, processing performance
Bearing parts in the course of consumption, to go through a lot of cold road, hot processing processes, in order to meet a small amount, high efficiency, high-quality request, bearing steel should have good processing performance. For example, cold, hot forming properties, cutting performance, hardenability and so on.
Bearing steel in addition to the above basic request, but also to reach the chemical composition of the appropriate, the average external organization, non-metallic dopants, external appearance defects meet specifications and appearance decarburization layer does not exceed the requirements of the rule concentration.
