Abstract

Lubrication is one of the most important key technologies for reliable and durable machines in ultra high vacuum. Solid lubricants, which are pre-coated before operation by a certain amount thickness, are commonly used for the system. The life of present system is, therefore, determined by the wear life of the coating of lubricant. To extend its lifetime, a new lubrication method for in-situ and on-demand restoration of the lubricants called as "Tribo-coating" had been introduced, and its effectiveness as practical solid lubrication method for sliding element has been clearly shown. This paper introduces the unique advantage of excellent tribological performance of tribo-coating film for ball bearings, and the usefulness of the tribo-coating for friction control of ball bearings in ultra high vacuum is clearly shown.
