Our Mission

To support the integration of your technology with oil-free bearing technologies.

  

There  are several sources for foil bearings.  Most do not have  COMMERCIAL SYSTEM and MASS PRODUCTION experience.  There are not many  experienced engineers who are able to help you reduce the risk  of integrating these new technologies with your proven technologies.  We  present the combination of formal theory with valuable hands-on  experience, bringing all the elements together.  From risk assessment  to design reviews to complete machine design, Oil-Free Machinery  complements your team.
