Pivot Works or All Balls are the best aftermarket kit brands.
I go through front wheel bearings twice as fast as rears for some reason? Must be all that mud we ride Bob. The dust seals on the front wheel cut a groove in the aluminum spacer quickly and muddy water gets in.

where might one find sealed bearings for the front wheel?
NCMM, I installed a set on my WR426 (sold now) and I got the "Pivot Works" and they were rubber sealed. I dont k now the bearing numbers for the front wheel of a WR, but they are a standard size. If you could get the size from someone in here, ie 6202 (example size), just convert it to 6202-2RS (the 2 RS means two rubber seals, a 1RS is the same, but a seal on one side, open on the other) and call a local bearing supplier or get the pivot works set. There is also "sheilded" bearing, these have a metal sheild, and are not sealed, but look like it. These are only good for bearings next to heat. They will be ID'd like 6202-2XX, avoid sheilded, get rubber sealed. I looked at the Yamaha Fiche to see if there was a bearing size hidden in the part number. It may be a 6403, if it is, get a 6403-2RS. But these sizes are only speculation on my part. Not sure if they are correct. Good luck

If you decide to go down that rout, give the engineering shop your old collars and explain to them you want some made exactly the same but without the worn in grooves - they would be able to do it. They may even come up with an idea of removing the optimum amount of material to make them relatively light, with SS being a heavier material than aluminium.

NOTE: On my former 426 rear-wheel I did not service the the bearings timely, which caused the balls to get out of the bearing which entered into the HUB and literally worked their way out. SO TIMELY CHANGE YOUR BEARINGS, the should cost less than R$15 a pair.
