The Importance of slewing Bearings, the "Precision Core" of Medical Equipment

In modern medical and precision instrumentation, high precision and reliability are paramount design criteria. From diagnostic imaging to surgical robots, from laboratory analyzers to radiotherapy platforms, every rotational movement and every positioning operation relies on a stable and reliable bearing system. Bearings are not merely mechanical support elements; they are also critical components that influence the precision, safety, and lifespan of medical equipment.

In medical applications, bearings must meet the following requirements:

• Ultra-high rotational accuracy

• Low noise and vibration operation

• Pollution-free and long-term operation

• Corrosion resistance and easy cleaning properties

• Special materials: 316L stainless steel, medical titanium alloy, ceramics and other materials with high compatibility

This requires the use of high-precision bearings for medical equipment to ensure stable operation and enable accurate medical diagnoses for doctors and users.
