Special shaft limits are required in certain cases and a variety of standard fits can be used, including even a press fit. The recommended values are in table A-14. For special requirements, contact your Timken engineer. TABlE A-14. gRA-RR sERiEs, RElUBRiCATABlE Bearing No. Shaft Dia. Basic Outer-Ring Size Housing Bore Shoulder Dia.
