7.1)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.
8.main market:America, Britain , Europe, Africa, Middle East and Southeast Asia etc.
