Robot ultra thin wall precision thin section bearings are professional core components for industrial robots, collaborative robots and humanoid robot joint rotary systems. Adopting equal cross-section ultra-thin wall design, the bearings maintain consistent cross-section while expanding the inner diameter, effectively saving installation space and reducing overall equipment weight. Manufactured from high-purity bearing steel or stainless steel materials, processed through precision grinding and heat treatment, they achieve low friction torque, high rotational accuracy and stable operation. The series includes deep groove ball type, angular contact type and four-point contact type, which can bear radial load, bidirectional axial load and tilting moment load independently. Widely used in robot wrists, forearms, rotary joints, precision turntables and compact automation equipment, supporting high-precision repeated positioning and long-term stable operation.
