Self-lubricating Composite Bearings for Vacuum and High Temperature Applications
Liquid lubricants and graphite have their limits
As a rule, friction bearings need lubrication. This is because of the low lubricity and insufficient dry running capability of the hard materials – such as Silicon Carbide – used for the running surfaces.
However, liquid lubricants and graphite fail at high temperatures, especially under vacuum conditions, which, in turn, limits the functionability of the bearings.
Dry lubrication with Boron Nitride
HENZE Boron Nitride allows dry lubrication of friction bearings for many applications:
- in a protective atmosphere or under vacuum conditions
- for long-term operation at high temperatures
- incorporating HeBoSint® solid lubricant pockets or HeBoFill® Boron Nitride powder within the SiC bearing material.
- applying hybrid dispersion layers containing HeBoFill® in a metal matrix (by electroplating) or coatings with HeBoFill® embedded in a polymer matrix. In both cases the Boron Nitride particles embedded in the running surfaces of the bearings will act as microscopic lubricant pockets.
This can be achieved by means of …
