Your existing bearing has the sizes of
Bore .562 (9/16) (14.28mm)
O/D 1.75 (1 ¾) (44.45mm)
Width .812 (13/16) (20.638mm)
Cone width .8880 (22.55mm)
Cup width .5625 (20.638)
The nearest metric equivalent is 30203
Bore 17mm
O/D 40mm
Width 13.25mm
Cone width 12mm
Cup width 11 mm
Therefore you would need to sleeve both the bore, housing and have a spacer to allow for the difference in depth
