7.main market:America, Britain , Europe, Africa, Middle East and Southeast Asia etc.
- application: These bearings are mainly applied to machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, printing machines and other installations
9.1)since these bearings have acontact angle, they can significant axial loads in one direction togertherwhith radial loads because of their design ,when a radial load is applied,an axial force component is produced ;therefore, two opposed bearings or a combination of more than two mudt beused.
2)since the rigidity of single-row angular contact ball bearing can be increased by preloading ,they are often used in the main spindles of machine tools ,for which high runningaccuracy is required.
