Bearing Sleeve

Precision positioning in automation starts with the Bearing sleeve, the component that holds the rotating heart of your machine. We manufacture these sleeves for industrial robot joints, servo motors, and precision rotating mechanisms. Using 45# steel or GCr15 bearing steel, our factory ensures each Bearing sleeve features IT6-IT7 grade inner diameter tolerance and high coaxiality (≤0.015mm). This level of precision minimizes rotation runout and significantly improves the transmission stability of your automated assembly lines.

Since our establishment in 2011, we have focused on technical leadership. Our Bearing sleeve is designed with high rigidity to withstand the high-speed and high-precision demands of modern robotics. In our Hubei facility, we apply advanced surface treatments like phosphating or blacking to ensure each sleeve is resistant to wear and rust. As a primary joint supplier for Sany, we maintain a dedicated QA department that monitors the entire production flow, ensuring that every sleeve provides a perfectly snug fit for your bearings, extending the life of your entire drive system.
