The public service grade of rolling bearing is divided into 0 (usual); 6x; 6; 5; 4; 2 grade accuracy grade. The grade is improved by 0 (normal) grade → 2 grade. The 6x grade is aligned with tapered roller bearing. The public service level between 0 (normal) and 6 is selected; the normal bearing is selected to be the 0 (normal) level of public service. The public service level is in the bearing code of P6, P5, etc. Indicated; 0 (normal) level is not indicated in the code name.
Rolling bearings are one of the most standardized and highly serialized parts in mechanical parts; suitable for mass production. Cooperation between bearings and other parts; regular bearing inner diameter and shaft cooperation use base hole to cooperate with public service; bearing outer diameter and The cooperation of the bearing housing hole is based on the basic shaft system. The cooperation is based on the inner and outer diameter of the bearing.
