The main types of bearings used radial load to bear, under certain axial loads, such as rolling bearings Road outside of spherical shape, it has a strong Tiaoxin performance, that is, when the rotary bearing center of the radial bearings and not vertical plane, still bearing the normal work of the species carrying capacity of the bearings, very low speed limits. Widely used in mining, oil and other machinery. The types of roller bearings are two structures, one is symmetric and non-symmetric, asymmetric type will be eliminated gradually. Its Hole 1:12,1:30 a conical hole and two cylindrical hole. The company in the production of bearings on a greater productivity, diameter 90 -- 1,500 may production, but also the production of non-standard dimensions of Spherical Roller Bearings.
