Hybrid bearings using ceramic balls are designed for applications where high grade electrical isolation is necessary and / or high speeds occur. The bearing lifetime is extended because electrical corrosion can not occur and high speed operation seizures are avoided. The robust design, together with a combination of steel and ceramics, makes the bearings useful for many different applications.
Machine tool spindles: State of the art machining processes, like high-speed milling, require a new concept of bearing arrangements for spindles. The application of hybrid bearings has resulted in a remarkable improvement in performance. For many years we have successfully used spindles with hybrid bearings for our own production processes.
Vacuum Pumps: The reliability of these bearings is of utmost importance, as a breakdown can result in high costs.
Medical equipment like X-ray tube bearings
Emergency bearings, like touchdown bearings, for magnetic bearing systems
Bearings for aeronautic and aerospace applications
