Composition of Hybrid Construction Ceramic Ball Bearings

Mar 17, 2017


Ferrule and rolling are indispensable elements of bearing. As the two elements are not the same material, there is a statement named hybrid construction bearing. When the rolling body uses ceramic materials, it is defined as hybrid construction ceramic ball bearing. Zirconia (ZRO2) and silicon nitride (SI3N4) are commonly used as ceramic ball materials; bearing steel (GCR15) and stainless steel (440,440C,304,316,316 L) are commonly used as ring material. According to using environment, speed, load, temperature and using requirements, the ferrule and rolling of ceramic ball bearings can be combined with the above materials and play different using effect.
