Outline

If hydrogen infiltrates the rolling contact surface of a roller bearing, white structure flaking may occur, significantly reducing the service life of the roller bearing. However, the mechanism behind white structure flaking is not fully understood. As a first step in clarifying the basic mechanism of white structure flaking, the paper identified the effect of hydrogen which causes fatigue behavior.

Looking to the future, NSK will continue to pursue products and services of the highest quality, offering greater reliability and further reductions in energy loss. As a product manufacturer, NSK is working to achieve a sustainable society that is both affluent and preserves the global environment.
