From first fully understanding your challenges to leveraging our in-house concept, design, high speed bearing testing and prototype bearing production facilities, our services make customized engineering expertise affordable.

Xdot has developed, proven, and patented a novel foil bearing configuration that delivers cutting-edge performance while reducing customers’ risk as well as development and production costs when compared to traditional bump foil designs. Our unique foil bearing configuration has more design flexibility, is easier to build, and has fewer parts than conventional bump foil designs. This translates to more efficient use of your project time and money.

Xdot Air and Process Gas Lubricated Foil Bearings can help you design a faster, cleaner, more efficient machine for your application.
