The QJ1000 series double row angular contact ball bearing is a high-performance bearing designed to withstand radial and axial loads. This kind of bearing adopts a double-row design, which can provide higher load-bearing capacity and better rigidity, and is suitable for high-speed and high-load working environments. Its angular contact design enables it to effectively share the load during use and improve the stability and reliability of operation. The QJ1000 series is commonly used in machine tools, aerospace, automotive and other industries, and is suitable for applications requiring precise positioning and low friction. This series of bearings have excellent wear resistance and corrosion resistance, extending service life and reducing maintenance costs.
