You're not setting bearing "load"............you're setting axial clearance in the bearing.

The indicator should have a magnetic base and you stick it on the rotor. Adjust the arm so that it contacts the end of the spindle (cap removed).

You observe the indicator while attempting to force the rotor outward and inward. The indicator will probably move about .005" and you'll hear a slight clunk when you do it. Now, gradually turn the adjustment screw clockwise...........in very small increments...........until you slowly creep up on a clearance of .0005". Anything less than .001" will be fine, but be sure the needle still moves. Tighten the clamp...........recheck the clearance and confirm that it's still OK..........remove the indicator and reinstall the cap.

Nope............the $99. unit might last a bit longer.

$18 sounds a bit too low for an indicator with a mag base and some adjustable arms. Remember you must reach out and over to the spindle.

I think I paid about $60. for this one.

Harbor Freight has them for about that regularly... sometimes less on sale...
I have used mine and checked it with feeler gauges and it was plenty close to correct... I also have an Enco... same results...
