One-way, two-way pressure ballbearing cage generally use steel stamping molding, large size or special use of the bearings are made of brass or mild steel turning cage.
单向、双向压力球轴承保持架一般采用钢板冲压成型，大尺寸或特殊用处的轴承则采用黄铜或软钢车削保持器。

In most cases the cross section of the bearing rings of a stainless steel deep groove ballbearing is very thin and the side faces correspondingly slim.
在多数情况下，不锈钢深沟球轴承的轴承圈横截面很薄，因此侧面也就很薄。
