I'm installing a new set of RUSLOW rotors & Hawk pads (Front/Rear) on 02 Harley Screw with low mileage (< ~2K). The new rotors have the bearing races installed,... so the ?'s I have are:

1) Do the bearings & races have to be a new matched set ?
(ie; both new & sold as a set?)
2) Can I use my old bearings (inner / outer rollers with less than
2K miles) with the new front rotor / races?
3) Can I just inspect / clean / repack & install (with new grease
seals) my current bearings ?

Thanks in advance.

If the bearing felt and sounded ok before, there should be no problem reusing them.

Also, the bearing and the race that is pressed into your new rotors should be built to the same specs.

When you pack the bearings and load everything back on to the spindle, you'll know almost instantly if they're a match when you seat the bearings. The rotor just wont spin right, or it will have excessive play, even when the spindle nut is completely tightened.

Then again, bearings are not that expensive. If you just want piece of mind, put new ones in.

If I were you, I'd just use the old bearings.
