Features
Highly reliable and long-life bearing steel
- The Company developed a new steelmaking technology to reduce harmful non-metal inclusions in steel to the utmost limit and, at the same time, an inspection technology for assessing the minimum existence frequency of those by a large volume; by combining these two technologies, high reliability and enhanced life has been enabled.
Merit
Improved bearing life and reduction in size and weight
- Since the reliability to steel cleanliness has been greatly improved, short-term breakage of bearings, which is the final product, can be suppressed and an extended life can be expected.
- The bearing reliability has been improved, and reduction in size and weight of components can be expected.
Application
- To increase the life and reliability of bearings, etc. which are used under severe conditions.
- To miniaturize and reduce weight of transmission bearings for automobiles, etc.
