Deep groove ball bearings can usually install space is restricted. In most cases, the shaft diameter (or bearing diameter) is based on the mechanical design or other design constraints. Selection of bearing type and size is determined by diameter of SKF bearings. Thus, bearing the main dimension tables are prepared in accordance with international-scale diameter size.
1, through the surface felt bearing quality
Deep groove ball bearings found in many customers say that as long as the process of bearing surface brightness is good quality, this is wrong. SKF bearing surface should be the kind of glossy black, this glossy black is bearing caused by using the standard steel and its grinding and cutting fluids are used by, in which the two previous.
2, chamfer is bright
SKF bearing a chamfer does not dictate the quality of bearing, but reflects the processing method of the bearing. Chamfering is black, stating after quenching heat treatment to increase the hardness of bearing, and some people believe that bad angle of the Black Watch is not processed completely, this is a misunderstanding.
3, good one cage than two-body, although the new process uses one cage, but it only saves material, rotation, and other properties than the difference of the two.
Overall, SKF bearing life and relationship factors 3, a deep groove ball bearing their own quality. The second is to use environment. Third, the installation method.
