Second, the bearing structure: 1, the size of the space Shenzhen cheap bearings, including the inner diameter of the bearing, ball bearing outer diameter, thickness and so on; 2, carrying capacity, including the size, direction and nature; 3, the speed limit; 4 rigidity,; 5, tolerance level; 6, aligning performance; 7, installation and removal requirements; 8, prices and availability; 9, support form. A, type of bearing a clear representation of the basic dimensions of bearings bearing original clearance, cage type, sealed form, an aliquot of the machine bearing lubrication requirements, it must be clear before starting the installation bearing model is correct. B, locating bearing of a shaft for smooth operation, generally at least two fulcrum for axial and radial support, and each has at least one or more pivot bearings. In general, a bearing positioning action bearing play, a bearing is not afford additional positioning action. In exceptional circumstances, the two bearings at the same time play a role in positioning. Locating bearing provides radial support and axial orientation. Therefore, locating bearing must be fixed to the shaft and the bearing housing. Deep groove ball bearings, spherical roller bearings, double row angular contact ball bearings, a pair of single row angular contact ball bearings can be used as locating bearings. A pair of tapered roller bearings can be used. Without flange bearings and cylindrical roller thrust bearing radial clearance with, but also can be used as locating bearings.
