1. ISO Dimensional system and bearing numbers

· ISO Dimensional system and bearing numbers 1.1 ISO Dimensional system The boundary dimensions of rolling bearings, width, and chamfer dimensions have been standardized so that common dimensions can be adopted on a worldwide scale. In Japan, ISO 281:2007 specifies methods of calculating the basic dynamic load rating of rolling bearings within the size ranges shown irdance with good manufacturing practice and basically of conventional design as regards the shape of rolling contact surfaces. · Rolling bearings: ISO: ISO/TC 14: Shafts for machinery and accessories: ISO: ISO/TC 108/SC 2: Measurement and evalhanical testing of metals: ISO .
