Thin walled bearing is a special type of bearing with extremely thin wall thickness. Its cross-sectional height is much smaller than that of standard bearings, but it can provide the same load-bearing capacity. It is mainly used in precision equipment that requires space saving and weight reduction, such as industrial robot joints, medical equipment, aerospace components, optical instruments, and small servo motors. Its characteristics are compact structure, light weight, while maintaining high rigidity and rotational accuracy, suitable for application scenarios with strict requirements for space and weight.
