Tapered Roller Bearings Tapered Roller Bearing Fitting Practice Tables The fitting practice data given in the following tables conforms to industry and ABMA/ANSI AFBMA/ANSI standards. These tables apply to solid or heavy-sectioned steel shafts, heavy-sectioned ferrous housings and normal operating conditions. Certain fitting practice data given in these tables may not be adequate for applications involving very heavy loads, very high speeds, unusual thermal conditions, light shafts and housing sections. In certain cases the method of assembly and the means and ease of obtaining the bearing setting may require fits different from those given in the tables. Fitting practice for nonadjustable TNA and TNASW two row bearings are shown on pages 184 to 195. Shaft and housing material, geometry, hardness and surface finish must be carefully controlled. Ground shafts should be finished to 50 micro-inches AA or better, for turned shafts a finish of 100 micro-inches AA or better, and housing bores should be finished to 160 micro-inches AA or better.
