Deep groove ball bearing generally consists a pair of rings, a set ofcage, a set of steel balls. its simple structure and easy usability makeitself as the most common and most widely used type of bearings. Thiskind of bearings is mainly used to bear radial load, moreover, it alsocould withstand a certain amount of axial load.
When increasing theradial clearance of bearing, this kind of bearing has properties of anglecontact ball bearing to bear a large axial load within a certain range.After assembled on shaft, the deep groove ball bearing can make theaxial displacement limit of the shaft or shell within the bearing’s axialrange.
Meanwhile, when the shell hole and shaft (or IR to OR) arerelatively tilted(within 8-16′,according to clearance), the bearingcould still work as normal, but the service life is reduced.
