Questions about this item

Which ZIBOO NTN 21315 spherical roller bearing size matches a 75 mm shaft and 160 mm housing?

The bearing with inner diameter 75 mm, outer diameter 160 mm and width 37 mm fits those dimensions directly.

What does the 37 mm width mean when the bearing is installed in a motor or gearbox?

It sets the axial space the bearing occupies on the shaft, so the housing shoulder and any spacer must accommodate exactly 37 mm.
