The metallurgical structure of the bicycle bearing steel ball has different density under different crystal structures such as martensite, austenite, bainite and ferrite during the operation, and also affects the crystal fineness. In the finished steel ball, due to the different chemical components such as iron, carbon, chromium, manganese, sulfur, phosphorus, etc., the hardness and impact wear of the steel ball have different degrees of influence. Generally, when the chromium content is large, The steel ball has high wear resistance.
Bicycle bearing steel balls can be used in a variety of machines and equipment with rotating parts when used, and designers often decide whether ball bearings or fluid film bearings should be used for specific applications. The following characteristics make ball bearings more desirable than fluid film bearings in many applications.
1. The bicycle bearing steel ball has a small starting friction and suitable working friction.
2. Can withstand radial and axial combined loads.
3. Not sensitive to the interruption of lubrication.
4. No self-induced instability.
5. Low temperature start is easy.
The bicycle bearing ball is within a reasonable range, so that the load, speed and working temperature can be effectively changed to a certain extent, and the ball bearing has a small effect.
