Look at this picture and you can see the split inner, which can be carefully separated...not that you should do this, of course....
Sorry I should have been more clear. I was referring to the dust cap - it is pressed onto the hub.

Unless they are sourcing the bearings from somewhere way outside normal engineering channels there are no workable waterproof sealed for life bearings available that are suitable for prolonged(more than hitting a puddle) immersion and automotive use-specially in salt water.

AFAIK the 'sealed for life' tag comes from the fact that normal people can't get them apart and the grease is sealed in for life by the rubber seal. There's certainly no way they can be guaranteed to be sealed for life if they are dunked in the water while warm/hot unless they are airtight too-and that simply isn't possible at the cost you want to pay for a bearing.

Ah ha.. If you take 'em off with a bit of care.. I use a small, blunt cold chisel.. you can reuse them, no problem. I drive them back on with a bit of tube tickled out to fit on the flange/lip rather than hit the top/crown.. it keeps 'em nice and square...

Oi !! I represent that remark.. I'm as "normal" as the next man..... well certainly the bloke next to me.. now he's weird....

Nah.. a few simple tools... a bit of guidance ... and the use of a good press... and anyone can do it....although, I'm not saying you should....

The point is, you know what you're doing. This hypothetical 'anyone'is quite likely to start by having to ask what a chisel is, have his fingers sewn back on twice and break his jaw/teeth/nose when the cheap ratchet slips ( Breaker bar? What's that? )

Then eventually he'll give up and pay someone who knows what to do to remove the teeth and hair from the stub and fix the problem

I thought you were a bit more advanced than knowing where to hit with a 2lb lump hammer

Am I missing something????

Is it not possible to make a hole in the seal (which, if my memory serves right is made of a soft material like nylon) on the sealed bearing and just fire in some grease every now and then? (in effect, turning it into a good-old fashioned ball-race?
