C3 is the standard clearance for bearings, and what most bearing companies would sell you if you didn’t ask for a specific clearance. We are talking .oooo “ differences , so it isn’t like you will know the difference.

The seals easily pop off if you buy sealed both sides , then want to lube them at a later date.

I buy sealed bearings wherever it makes sense, dirty wet locations like wheels, swing arm, etc are best sealed , but if you’ve ever popped the seal off an old bearing, there usually isn’t much grease left. I like to use boat trailer grease which should give better moisture protection when i grease bikes. That still doesn’t mean you should use a pressure washer on your hubs or swing arm pivot though.
