Generally, the installation space of self-aligning ball bearings is limited. In most cases, the shaft diameter (or the inner diameter of the self-aligning ball bearing) is limited by the mechanical design or other design. Therefore, the type and size of self-aligning ball bearings are determined according to the inner diameter of self-aligning ball bearings. As a result, the main dimensions of the scale self-aligning ball bearings are compiled according to the internal diameter of the international scale.
The size of the form scale self-aligning ball bearings are in the design of mechanical device is best to use scale self-aligning ball bearings (the design of self-aligning ball bearing is easily purchase here aside, some entrance self-aligning ball bearing catalog models do exist, but some non-standard self-aligning ball bearings, in China no spot, sometimes the futures market for a long time, so the self-aligning ball bearing selection must consider the time cost and the cost of a late replacement) self-aligning ball bearing the load exerted on the self-aligning ball bearing load, the nature, size and direction is changeable. Generally, the rated basic load is displayed on the size table. But axial load and radial load are also important factors to select suitable self-aligning ball bearings. When the size of ball and needle aligning ball bearings is equal, the needle roller self-aligning ball bearings usually have higher load capacity and bear larger vibration and impact load.
