low noise and stable operation .
Gearboxes and Transmission Systems: Suitable for reducers and lightweight drive shafts. Its sealed
design (ZZ dust cover) effectively prevents dust ingress, extending
service life .
3. Consumer Electronics and Home Appliances
Curling Irons and Beauty Devices: Heat-resistant design adapts to environments with heating
elements, commonly found in personal care devices .
Rotating Components in Home Appliances: Such as fan motors and air purifier blades, utilizing its
thin-wall design to save space .
4. Special Industrial Fields
Medical Equipment: Some diagnostic instruments use this type of bearing in their
rotating modules because it meets low-vibration requirements .
Automation Equipment: Suitable for robotic arm joints and small transmission units in
automated production lines.
