Thin-walled bearings are a type of bearing that achieves an extremely thin cross-section and a compact, lightweight design. They are generally classified into different sealing forms, such as rubber sealed - RS and metal sealed - ZZ, and use small outer diameter steel balls to achieve low friction torque, high rigidity, and excellent rotational accuracy. Meanwhile, the hollow shaft design in thin-walled bearings ensures lightweight construction and wiring space.

Core Features:

1. Lightweight Design: By reducing the diameter of the steel balls and adopting a thin-walled structure, the weight is reduced while optimizing the equipment layout.

2. High Precision and Rigidity: Utilizing precise manufacturing processes ensures rotational accuracy and enhances resistance to deformation.

3. Rotational Performance: With a low friction coefficient design, it is suitable for high-speed operation scenarios (maximum speed up to 6500 r/min).

4. Diverse Structures: Including rubber sealed (RS), steel sealed (ZZ), stainless steel, wide width and other special models, to adapt to different working conditions.
