Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 7218-1995 "to miniature ball bearings with flanged outer ring rolling bearing dimensions", and GB/T 7218- Compared to 1995, the main technical changes are as follows. --- Remove the dust cover schematic structure bearing the legend to legend (see Figures 1 and 2, 1995 edition of Figures 1 and 2); --- Increasing the size of series 17 and 18 with a dust cover flange outer deep groove ball bearing dimensions (see Tables 1 and 2); --- Series of 19,39,10,02 and increase the size of the flange of the outer ring of deep groove ball bearing with a ring of 03 dimensions (see Table 5 to Table 9); --- Removed r1smin value flange outer deep groove ball bearings (see the 1995 edition of the Tables 3 to 9); --- Remove the 28 series d = 3mm flange outer deep groove ball bearing type and dimensions (see Table 3 of the 1995 edition). The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee of Rolling (SAC/TC98) centralized. This standard was drafted. Luoyang Bearing Research Institute Co., Ltd., Zhongshan City, Pacific Century Bearing Manufacturing Co., Ltd. The main drafters of this standard. Song Yucong, Chen Qingxi, Chen Taiping.
