In the rotating gantry and slip ring systems of high-end medical imaging equipment (such as CT scanners, MRI, and PET-CT), medical CT scanner bearings play an absolutely core role in ensuring high-speed, smooth scanning and imaging quality. Medical imaging equipment has extremely stringent requirements for bearing rotational accuracy, noise levels, and electromagnetic compatibility. The minute vibrations and friction noise generated by traditional bearings during high-speed CT gantry rotation are directly transmitted to precision detectors, causing artifacts in medical images. Meanwhile, ordinary steel bearings are prone to eddy current heating and magnetic interference in strong electromagnetic fields, severely affecting imaging accuracy and equipment safety. Hospitals and equipment manufacturers urgently need support bearings customized for medical CT scanners, featuring ultimate high precision and electromagnetic-interference-resistance.

Facing the stringent requirements of medical imaging for "absolute clarity" and "ultimate silence," support systems must not only possess extremely high rotational smoothness but also achieve non-magnetic interference and ultra-low heat generation in complex electromagnetic environments. Due to material and structural limitations, traditional bearings are highly susceptible to wear and increased clearance under long-term high-frequency start-stop and high-speed operation, triggering mechanical resonance. Furthermore, their metal components are easily affected by magnetic fields, becoming hidden dangers that interfere with precision sensors. The market urgently demands a medical-grade CT scanner dedicated bearing solution that can break through the dual bottlenecks of electromagnetic interference and mechanical vibration, achieving medical-grade high cleanliness and high stability, providing solid protection for various high-end medical equipment.
