The sealed magnetic bearing adopts a precision closed sealing structure and supports full immersion operation, suiting working environments with slightly corrosive process fluids. Its reliable sealing design blocks corrosive media, impurities and moisture, protects core bearing components and prevents corrosion, fouling and jamming. It applies non-contact magnetic levitation technology to achieve low wear, maintenance-free operation, quiet and stable performance. It perfectly fits general chemical and fluid transmission scenarios and delivers outstanding cost performance and long-term reliability.
