 A. The requirements of the spherical bearing to match the mechanical precision ASAHI 
 Precision ASAHI spherical bearing precision of less than 1μm, thus requiring its matching parts (shaft, bearing, end caps, retaining ring, etc.) have high dimensional accuracy and shape accuracy, especially with the surface accuracy control with ASAHI spherical imports bearing the same level, this point is crucial, but also the most overlooked. 
 Must also pay attention to precision ASAHI spherical bearings to match parts up to the above requirements, often Precision ASAHI spherical bearings after installation error several times larger than the original ASAHI spherical bearings, or even 10 times more than the error, not a completely its precision ASAHI spherical bearings, and match parts of the error is often not simply superimposed on the the ASAHI spherical bearing error, but that go together to a different magnification. 
 Two. Spherical bearings with the precision ASAHI 
 After installation in order to ensure ASAHI spherical bearings do not produce excessive deformation, we must do: 
 (1) axis of the bore roundness and verticality of the shoulder block in accordance with the corresponding accuracy of the spherical bearing ASAHI requirements. 
 (2) it is necessary to accurately calculate the rotating ring with the amount of interference, but also the accurate calculation of the appropriate co-ordination of the fixed ring.

 The rotating rings the amount of interference to the extent possible, should be made smaller. Ensure the impact of thermal expansion of the operating temperature, and the maximum speed the centrifugal force of the impact of creeping or sliding so as not to cause a tight fit to the surface. Fixed ring based on the work load size and the the ASAHI outer spherical bearing size, select a very small clearance fit or interference fit too loose or too tight are not conducive to maintaining the original precise shape. 
 Cold rolling expansion process is one that enhances the utilization of materials, increase the density of the metal structure, to keep the stream of metal to the advanced technology of the linear method, it is a scrap processing methods. In theory, cold rolled formed products were not turning the heat treatment and grinding. At present, the cold rolling process is mainly used in small deep groove ball NSK one-way bearing, as its main process: 
 The rough forging (ring) - turning (in addition to the channel) - Rolling (groove and chamfer) diameter - soft grinding both ends of the surface. 
 The process of cold rolling and forging molding process, the accuracy of the product in addition to affected by the precision equipment, but also by the effects of mold precision. 
 3) Turning Shaping: 
 NSK one-way bearing industry, turning molding technology is the use of special lathe with centralized processing method to complete the molding process. However, due to the method used by the device to adjust the difficulty, low-precision machine tools, material utilization is low, the process is being phased out.

 With the development of science and technology, the rapid development of CNC turning machines, and has improved steadily. At present, a number of complex shape, high precision products are increasingly using the molding technology of CNC turning. 
 In summary, the rings forming the direction should be toward the development of a metal material utilization is high, high efficiency, high precision molding direction. Therefore, the high-speed upsetting, cold ring rolling technology, CNC turning molding technology will be more and more applications.
