Mixed bearings (Hybrid construction bearing) statement. When the
rolling body adopts the ceramic material, it is defined as a mixed
ceramic ball bearing (Hybrid construction ceramic ball bearing).
The commonly used ceramic ball materials are zirconia (ZRO 2) and
silicon nitride (SI3N4); the commonly used ring materials are
bearing steel (GCR 15) and stainless iron (440,440C) and stainless
steel (304,316,316L)
