Barden Super Precision X-ray bearing units enable scanner applications to provide images of the highest resolution

With Barden into the future of x-ray technology

We continue to keep pace with advances in x-ray and CT technology with new, improved x-ray tube bearing designs. These bearings, which are used to support the spinning x-ray anode, operate at speeds in excess of 10,000 rpm under harsh conditions. In addition to withstanding the passage of high voltage, the bearings must also operate in a vacuum environment down to 10-8 torr and at temperatures of 750–900°F (400–500°C).

The x-ray bearing units are full ball complement designs and have integral races on the shaft. The shaft has a flange for attaching the anode. The units have either solid or spring preloading, depending on application requirements. In order to provide effective lubrication under these extreme conditions, we utilize advanced surface engineering technologies such as plasma and ion-beam assisted deposition. The performance of x-ray tube bearings is evaluated and verified by Barden in its in-house x-ray bearing test facility under simulated thermal and vacuum test conditions.

Advances in x-ray technology – this means higher quality in diagnostics and therapy, while offering treatment that is kind to patients. This involves faster data acquisition as well as highresolution imagery. Our x-ray tube bearings are the clear choice for advanced x-ray and medical scanner applications.
