X-ray Tube Bearings
X-ray Tube Bearings
The preferred choice of the world's leading X-ray tube manufacturers
Ultimate precision under 550°C high temperature and high vacuum conditions
The Global Benchmark in X-ray Tube Bearings
myonic bearing assemblies are used by the world's leading X-ray tube manufacturers for OEM and replacement X-ray tubes, ensuring high-precision, clear image generation.
All X-ray tube bearings are designed for high vacuum and high temperature environments. myonic's ball bearing systems achieve precise, low-loss, vibration-free operation in all directions through dry lubrication at temperatures up to 550°C.
Reliability Under Extreme Conditions
Six key technical advantages designed specifically for X-ray tube rotating anodes
High Temperature Resistance
Utilizing high-temperature tool steel and dry lubrication (lead/silver film), maintaining stable operation under extreme temperatures generated by the rotating anode.
High Vacuum Compatibility
Dry lubrication completely replaces conventional grease, eliminating volatile contamination risks and ensuring X-ray tube vacuum integrity.
Vibration-Free Precision Operation
Strict noise and vibration specifications ensure X-ray image clarity and repeatability, reducing image artifacts.
High-Speed Rotation Capability
Up to 10,800 rpm, maintaining stable operation under high centrifugal loads (50g) in high-end CT scanners.
Thermal Compensation Design
Thermal compensation / preload design addresses the rapid thermal expansion of the rotating anode, maintaining optimal preload across a wide temperature range.
Custom Engineering Support
myonic engineers engage from the early tube design stage, providing rotor dynamics analysis, FFT analysis, and critical frequency calculations.
Diagnostic / CT Scanning 
Vascular / Cardiac Imaging 
High-End CT Neuroimaging Three Application Segments
Providing optimally specified bearing units for different imaging equipment requirements
Diagnostic / Mammography
Stationary tubes have relatively low mechanical demands. Bearing designs are highly standardized, with multiple connection specifications available from the myonic standard series.
Mid-Range CT / Angiography
Tubes rotate or move around the patient during use, requiring larger mechanical loads and higher temperature tolerance. myonic provides larger bearing components.
High-End CT
The X-ray tube rotates around the patient at up to 4 revolutions per second, with lateral acceleration reaching 50 times gravity. myonic bearings are optimized for these extreme conditions.
