The QJ200 series double row angular contact ball bearing is a high-precision, high-load-carrying bearing that is widely used in mechanical equipment, especially where it is necessary to bear axial and radial loads. This series of bearings has a double-row design that provides higher stiffness and stability. Its angular contact structure effectively reduces friction and wear during high-speed operation, thereby extending service life. QJ200 series bearings are usually made of high-quality steel, and the surface is specially treated to be corrosion-resistant and high-temperature resistant. In addition, the inner and outer rings of the QJ200 series are reasonably designed, making it more convenient to install. Due to its excellent performance, this series of bearings are widely used in automobile, aviation, metallurgy, mining and other industries.
