The XD57-28.65/150 is a medical diagnostic rotating anode X-ray tube insert with an integrated bearing-mounted rotor, rated in the 150 kV class and designated for 28 kW and 65 kW focal spot loading. It is a glass-envelope replacement tube insert used inside the tube housing assembly of general diagnostic radiography X-ray systems. The unit is supplied new and CE marked.
What Is a Rotating Anode X-Ray Tube?
A rotating anode X-ray tube generates X-rays by accelerating electrons from a heated cathode filament onto a spinning anode disc. Because the disc rotates on a bearing, the heat of each exposure is spread around a full focal track rather than a single point. This lets the tube handle far higher exposure power than a stationary anode tube of the same focal spot size, which is why rotating anode tubes are the standard choice for diagnostic radiography.
Key Benefits of the XD57-28.65/150 X-Ray Tube
- 150 kV class operating voltage for general diagnostic radiographic techniques.
- Dual focus power designation (28 kW / 65 kW) giving a fine-detail setting and a high-output setting in one tube.
- Bearing-mounted rotating anode that distributes heat across the focal track for higher loading.
- Glass envelope insert with a clear view of the cathode, anode disc and rotor assembly for inspection.
- CE marked and supplied new, ready for installation by a qualified X-ray service engineer.
Features of This Diagnostic X-Ray Tube Insert
Rotating Anode With Bearing
The anode disc is carried on a rotor and bearing assembly inside the vacuum envelope and is driven by the stator fitted in the tube housing.
Dual Focal Spot Cathode
The model code 28.65 identifies two power ratings, one for the small focus and one for the large focus, so the operator’s generator can select detail or output as the examination requires.
XD57 Series Tube Format
The XD57 family is a widely used glass rotating anode insert format for medical radiographic tube housings. Always match the insert to your housing, stator and generator before ordering.

- Follow the tube rating charts and warm-up procedure to protect the anode and bearing.
- Handle the glass envelope with care and keep it clean before it is placed in insulating oil.
- X-ray equipment must be operated in line with local radiation safety regulations.
Frequently Asked Questions
What does XD57-28.65/150 mean?
XD57 is the tube series, 28.65 indicates the two nominal focal spot power ratings of 28 kW and 65 kW, and 150 indicates the 150 kV voltage class.
Is the XD57-28.65/150 a complete X-ray tube assembly?
No. It is the rotating anode tube insert. It is installed inside a separate tube housing assembly that contains the stator, insulating oil and high-voltage receptacles.
What is this X-ray tube used for?
It is used in medical diagnostic radiography systems as the X-ray source, typically as a replacement insert when an existing tube reaches end of life.
Why choose a rotating anode tube instead of a stationary anode tube?
A rotating anode spreads exposure heat over a circular track, allowing higher power and shorter exposure times than a stationary anode with the same focal spot.
Is the tube new?
Yes. The XD57-28.65/150 is supplied in new condition and is CE marked.
Who should install a rotating anode X-ray tube insert?
Only a trained X-ray service engineer should install, season and calibrate the tube, as the work involves high voltage, vacuum glassware and radiation safety checks.
