High Accuracy and Stability
conforms to international accuracy standards (e.g. ABEC-1 to ABEC-7), and the internal clearance strictly follows GB/T4604 (equivalent to ISO 5753) to ensure smooth operation .
Precision manufacturing process with strict tolerance control, suitable for high speed scenarios (e.g., motors, instrumentation).
Low Friction and Low Noise
Optimized design of raceway and steel ball reduces friction loss, together with special noise detection instruments (such as S0910-1) to control the noise level, suitable for equipment with quiet demand (such as medical instruments, office equipment).
Long Life and High Reliability
The use of high purity chrome steel material enhances wear resistance and fatigue resistance, prolonging the life of the bearings in continuous operation scenarios.
Dust caps (ZZ suffix) or seals (2RS) are provided to prevent contaminants from intruding and enhance reliability.
Lightweight and Miniaturization
With an outside diameter of only 16mm and a weight of only 0.0038kg, it saves space and reduces the overall load on the equipment, making it suitable for miniaturization (e.g., electric toys, miniature motors).

| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
