Abstract Lubrication technology for rolling bearings is an important elemental technology for providing suffi cient bearing performance. It has been developed for the purpose of reducing friction and wear, providing longer bearing service life, reducing the amount of lubricant consumption, reducing environmentally burdening substances, etc. This report introduces trends regarding greases for rolling bearing used in main industrial fi elds and examples of research and development results related to lubrication technology achieved by JTEKT.
