Outer ring tolerances and housing fillet radii correspond to equivalent 200-series single-row radial bearings. Continued on next page. TABlE A-10. HOUsiNg, sHOUlDER AND sHAfT DiAMETERs MOUNTING STANDARD SERIES MOUNTING DATA When shafts are selected for use with wide-inner-ring ball bearings, a minimum slip fit is desirable for the most satisfactory mounting. Special shaft limits are required in certain cases and a variety of standard fits can be used, including a press fit. The recommended figures are noted in table A-10. In some applications, it may be permissible to use increased shaft tolerances. In such cases, applications should be forwarded to your Timken engineer for complete recommendations. Bearing bore tolerances: in. - 2 3 /16 in., nominal to +0.013 mm, +0.0005 in.; 2 in. - 3 3 /16 in., nominal to +0.015 mm, +0.0006 in.; Recommended shaft tolerances: in. - 1 15 /16 in., nominal to -0.013 mm, -0.0005 in.; 2in. - 2 15 /16 in., nominal to -0.025 mm, -0.0010 in.
