With Step-quenching bright oil DF-S, the martensite step-quenching test for bearing component has been made. The test results show that the oil may significantly reduce the deformation and stress, increase crushing load of the steel ball and service life of the bearing.

采用DF-S油对轴承零件进行马氏体等温淬火试验，证明该淬火油可以显著降低变形和应力，提高钢球的压碎载荷及轴承的使用寿命。附图3幅，表3个。

While the bearing roller is quenched into UNCON ( 15w%) or water, it can get a lot of martensite. At the same time, the hardness and quenching layer of bearing roller meets the needs, but the residual stress is larger.

以UNCON（15%）或水为淬火介质时，可以得到大量的马氏体，支承辊硬度和淬硬层深也符合要求，但残余应力较大。
