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 even a press fit. The
recommended values are in table A-13. For special requirements,
contact your Timken engineer.

When the housing revolves in relation to the shaft, the housing bore dimensions shown on page 131 of the Timken Engineering Manual
(order no. 10424) should be used. Outer ring tolerances and housing fillet radii correspond to equivalent 200-series single-row radial bearings.
