 When installing sealed bearings, install the brake-side first so that the bearing is fully seated in the hub. This helps to keep the brake rotor alignment in conjunction with the external bearing spacer. Then place the internal hub spacer into the wheel and install the other bearing. Be sure that the internal hub bearing spacer is a few thousandth longer than the spacing of the hub bearing seats. This guarantees that the hub spacer will be in full contact with the inner race of the 2nd bearing and the bearing will not be laterally loaded (under tension). The outer race of the 2nd bearing should NOT fully seat against the hub cavity - You must stop the bearing insertion when the inner race of the 2nd bearing comes in contact with the hub spacer.
-Notice in the diagram that there is a small GAP between the outer race of the 2nd bearing (right-side of forks) and the seat of the hub cavity. This is important to maintain as described above to prevent laterally loading the bearing.
+Notice in the diagram that there is a small GAP between the outer race of the 2nd bearing (right-side of forks) and the seat of the hub cavity. This is important to maintain (as described above) to prevent laterally loading the bearing. The goal is to never put differential lateral forces on the inner vs outer races while installing the bearing. We don't want to damage either the balls themselves or their races by causing the inner race to go one way while the outer race is pushed or held the other way.
-When re-installing the wheel to the forks, the axle will slip completely thru the right-side fork. It will clamp all the parts - the external spacer, the right-side bearing inner race, the hub spacer, the left-side bearing inner race and the second external spacer - to the left-side fork. At this point, when you tighten the nut on the axle, the wheel assembly is only clamped to the left-side fork. The right-side fork is then clamped to the wheel assembly by the Pinch Bolt which now allows both forks to support the front wheel assembly. This process allows the forks to rotate individually and align themselves to the axle.

-If you are changing from a stock wheel, be sure your external and internal spacers are properly sized. The inner spacer must be a few thousandth longer than the measured distance between the two bearing cavities of the hub. The external spacers need to be the correct length to properly align the brake rotor with the brake caliper and also to center the wheel between the forks.

 The first part is a simple outer race while the second part is not only the inner race but includes the roller bearings in a cage. When installed, in addition to using the two bearing sets, there is a hub spacer, a spacer washer and, possibly, SHIM washers. Because there must be a precise space between the inner & outer races of each bearing set, shims are used in setting that precise distance.
-The outer races are simply installed fully into the hub cavity on each side of the wheel. Then, on the brake rotor side, the selected shims are installed, followed by the spacer washer, then the inner bearing race (with rollers) and the oil seal. On the opposite side of the wheel, you must insert the hub spacer (to fully contact shim washers), then the 2nd inner bearing race (with rollers) followed by the oil seal. Then the proper wheel spacers are inserted through the center of the oil seals to make contact with the inner races on each side.

Then the proper wheel spacers are inserted through the center of the oil seals to make contact with the inner races on each side.
 When assembled, between the front forks (or rear swingarm), the axle clamps the assembly together. The installed shims will create a gap between the inner & outer races to create the End Play (the ability of the wheel to move horizontally on the axle). You must check the End Play after clamping the axle components to be sure you are within the specs (typically, .002" to .006" combined total for End Play of the assembly). Check your factory manual for the recommended procedure.
