پœ Make sure that the radius, ra, of the shaft and housing is smaller than the bearing chamfer dimension, r (minimum) or r1 (minimum) to prevent the shaft or housing from interfering with proper bearing seating.

پœ When using a fillet radius, (ra2) larger than the bearing chamfer dimension (for enhancing the strength of the shaft or when shoulder height must be lower than specified in the dimension tables), install a spacer between the bearing and the shaft shoulder as shown in Fig. 8.9 and Fig. 8.10.
