Bore CodeSmall and medium bore sizesBore code x 5 = bore size in mm [ex., BORE = 20 x 5 = 100mm]

Large bore sizesBore code = bore size in mmExample: 232/600YMBW507C08[ex., BORE = 600mm]

Dimension SeriesSpherical roller bearings are broken down into a series based on their width (0, 1, 2, 3, 4) and outside diameter (8, 9, 0, 1, 2, 3).
