Theoretically, you may use linear row ball bearings, because they deal with some axial loads somewhat well. But the angular contact bearings, when axially pre-loaded, blocks the parasite radial play. At first I've think about using roller tapered bearings (as Flevobikes), but they need to be pre-loaded with a strongest loading. That's why they are pre-loaded with castle nuts to forbid the loosening. Aditionally, the roller tapered bearings are so large and havier than the angular contact ball bearings...
