Xdot builds our smallest and largest bearings ever

Two of our most recent projects have expanded our bearing size range.  We have been working on scaling, optimizing, building, and testing very small to very large foil bearings – in fact, the smallest and largest we’ve ever built!

Very small:  Our new bearings are for a small, 300,000+ rpm machine. The radial bearings are only 7 mm in diameter; the thrust bearing is smaller than a dime. We have taken full advantage of wing foil bearing unique features in scaling to this tiny size. For example, not needing to weld these very small parts makes for a much more practical and robust bearing.

Very large:  This application requires radial bearings of just over 125 mm bore, and a thrust bearing around 170 mm OD. These large bearings will enable a unique, process gas lubricated machine configuration under development by the customer.
