Repairing roller/bearing on a rowing machine

I came a cropper on my rowing machine this morning, when the seat, which
runs up and down an aluminium frame as you row, started making alarming
grinding noises. The seat runs on four rollers, and upon dismantling, I
discovered that two of these were badly worn, with one now completely
adrift.
Picture of the seat, upside down, is here:

The rollers are hard plastic (nylon?) and should be a firm fit on a
ball-bearing; however the inner surface of the roller is so worn that
there's now a deep groove in there, and it's no longer in contact with
the outer surface of the bearing at all:
http://img508.imageshack.us/img508/9201/bearing.jpg
I don't rate my chances of finding new replacments (obsolete and obscure
machine) and would like to attempt a repair by filling up the gap and
re-attaching the roller to the bearing. Not easy, owing to the
considerable load (ie, my not insubstantial body, in motion) it will
have to take. Any ideas?
As immediate solutions I'm thinking car body filler or Araldite? but
what about some form of liquid metal (which I know nothing about)?
Any thoughts appreciated...

I would not attempt to bodge something as I suspect that a sudden twist of
the seat when on the pull stroke could result in a lower back injury if the
repair failed
I would be looking to find a siutable replacement as a first solution
maybe worth looking here

I take your point, but TBH I can't forsee that sort of failure - worst
case scenario is either complete lock-up or failure of one out of four
wheels, which run in grooves - really no way for the seat to twist like
that.
Having got the thing in bits, it would be very easy to try a diy repair
even on the off-chance it works - just a case of knowing what product
best to try.

Nice try, thanks! But no - mine's a couple of mil bigger on all dimensions.

They look like they are rollers for a roller-shutter door, like the one in
the back of my truck. Any truck parts supplier/coach builder should be able
to supply these. They are very common and because they wear out quite
frequently, most places keep a stock of them.

I do appreciate all the suggestions for sources for replacements;
however AFAIS unless I can obtain exactly the right size it's not going
to work; at best even if I replaced all four with matching ones, I'd
still need a precise match on the spindle size. The ones on the Concept2
site look very close, but my spindles (not a Concept2 model) are about
1mm wider I think).
Hence what I'm really after is to attempt to repair mine - if a suitable
substance is available - and I would welcome a bit of discussion on that! :)

Can you drill out the broken one over-size and then sleeve it so it'll
accept the same kind of bearing? Or drill it to take a larger bearing.
The problem is, it looks like it relies solely on the friction fit of the
bearing to stop the wheel coming adrift - so drilling / sleeving and
getting the dimensions right might be tricky depending on what tools you
have access to.
I'm not sure about 'filling' it with anything, either - I mean you could
try epoxy, but I suspect it might fail, which might be painful when it
does!
Is there anytihing that keeps the seat in place other than the wheels?
What stops the whole seat from lifting off the bed - just body weight?
cheers

I'd have thought a complete rebuild with proper roller bearings as used for
heavy duty machinery in enclosures might be one way. Some pretty hefty
slides like those in drawers only larger should still be available. Back in
my youf, a company called Imhof used to make some capable of carrying people
but I bet they no longer exist like many UK quality companies owned by
Germans :-)

The wheels used under big glass patio doors is likely a better bet.

They're just doing what they couldn’t manage in WW2.
They hijacked the royals centurys before that.
