| *The
deviation from nominal taper is defined as the limits off (¡÷d1-¡÷d) where ¡÷d1
is the |
|
| actual
devistion of d1 from nominal bore diameter at larger end and ¡÷d is actual deviation |
|
|
| of
d from nominal bearing bore. |
|
| Diameter
d1 is obtained by the following formula: d1=d+0.0833338B where B is the |
|
| width
of the bearing inner ring |
