Bearings

X-ray Tube Bearings

These bearings are designed for medical diagnostic equipment such as X-ray machines and computed tomography (CT) scanners.

They are capable of operating in harsh environments such as vacuum and high temperatures, and are characterized by high load capacity, long lifespan, low vibration, and low noise.

Custom

The ball bearing system developed by myonic ensures highly accurate, low-loss and vibration-free running in every position despite temperatures of up to 550°C. Bearing flange and housing are designed according to customer request. Due to our great knowledge by being close to our customers we understand their applications and can apply this experience into ever-improving products.

Custom Case

Diagnostics / Mammography

In X-ray imaging, high power and very short exposure times are used to avoid quality degradation due to patient movement during the procedure. The rotating anode technology, which disperses heat by rotating the target (anode), enables the production of high-performance and long-lasting X-ray tubes.

Mammography is used for the early detection of breast cancer in women without signs or symptoms of breast disease, as well as for diagnosing breast diseases in women who have symptoms such as lumps or pain.

myonic's X-ray tube bearings excel in quiet operation and low vibration, which helps reduce stress for patients undergoing the procedure.

The X-ray tube bearings for mammography enable the capture of hundreds of thousands of mammograms, significantly contributing to the eradication of breast cancer.

Mid-CT / vascular

Computed Tomography (CT) is a special form of X-ray that provides much more detailed images than conventional X-rays. CT uses specialized hardware and software to create highly accurate 3D images and cross-sectional images of various parts of the body. CT scans are used for diagnosing conditions such as strokes and hemorrhages, locating lung tumors, abdominal tumors, and inflammations, as well as for detecting fractures and vascular issues.

X-ray tube bearings for intermediate CT/vascular applications rotate around the patient up to 4 times per second.
myonic's X-ray tube bearings provide high precision rotation and low noise in intermediate CT applications.

High-end CT

High-performance CT X-ray tube bearings rotate around the patient at a frequency of up to 4 times per second to generate multiple images. This subjects the high-performance CT X-ray tube bearings to lateral accelerations equivalent to 50 times the force of gravity. Simultaneously, the rotating anode spins around its own axis at up to 10,000 rpm.

The rotating anode must rotate with minimal vibration and noise. The high-performance CT X-ray tube bearings designed for this application achieve low vibration and quiet operation, and are capable of operating at bearing temperatures up to 550°C and in high vacuum conditions.

At myonic, we work closely with our customers to provide custom solutions that are optimal for their applications.
