The accuracy of the rolling bearing is divided into (primary) scale accuracy and rotation precision. The accuracy grade has been standardized; it is divided into 0 grade, 6X grade, 6 grade, 5 grade, 4 grade, 2 grade 6 grades. The precision is improved sequentially from 0 grade; Regarding the normal use level 0 has been met; but when used in the conditions or occasions shown in Table 1; the accuracy of level 5 or higher is required. The above accuracy level is based on the ISO specification; but its title is regulated in various countries. It is different.
Scale accuracy (items related to shaft and housing units)
1. The tolerance of the inner diameter, the outer diameter, the width and the installation width, the tolerance of the complex circle diameter and the diameter of the outer complex circle in the roller group, the allowable limit value of the chamfering scale, and the tolerance of the width of the rotation. Project related to the rotation of the rotating body)
1. The inner ring and the outer ring allow the radial runout and the axial runout. 2. The inner ring allows the lateral runout. 3. The allowable variation of the outer diameter surface inclination. 4. The allowable variation of the thrust bearing raceway thickness. 5. The tapered hole. Acceptance error and allowable variation

World Famous Paintings

The reason why some works become Famous Paintings is that the connotation they are intended to express is eternal. Although they were born in that era, they are also the major themes we pursue together in modern times. With the background of the times at that time and the subjective expression and refinement of painters, the works created in this way are called famous paintings, so they have far-reaching influence.
