Cartridge square taper BB 4 a Adamas AX square taper crank?
 
Anyone know if there's a Shimano square taper CARTRIDGE bottom bracket that I can put a square taper Shimano Adamax AX crankset on? My buddy wants one.. I have a Shimano Cartridge BB-UN51 but is seems as if the taper is different on it than on the crankset and thus the crankarms slide all the way to the shoulder of the spindle and the crankarms can be wiggled.
So, 1, are the tapers different and 2, is there a Shimano cartridge bottom bracket that'll work with the Adamas AX crankset?

Thanks and cheers

Right. Likely different section of the crank taper, besides
being most probably asymmetric.

If you know the original spindle specs (overall length and
the right/left offset) there may be a Campagnolo or Miche or
Phil Wood product. Our archive here only gets us to 'use
Shimano BB-SL-31', no specs or images sorry.

Thanks Andrew. I thought it might be another case of an orphan unit or an expensive workaround. Square taper cup and cone it'll be then.

Cheers

Nothing wrong with that at all. Some moderate attention to
cleanliness, lubrication and adjustment will give excellent
results.

It may not even be an unusual spindle format (if I recall,
it's not) but merely not of the "post-1990s cheap BB" style.

That's a great source but unfortunately the PDF documents I have show a splined bottom bracket not a square taper one. Thus I don't know if it's ISO or JIS but I think it must be an ISO one.

Cheers

Splined would be a Shimano Selecta crank

The bottom bracket in those images looks a lot like the splined Selecta crank. Note the splines in the images especially the one in the top right hand corner.

I looked at my crank to get the model number but the number is hidden by the chainrings and pant guard. I'm not about to take it apart just to see that number.

Cheers

The chainring assembly splines to the crank but
crank-to-spindle is square, note image of crank & spindle,
lower right.

Thanks again Andrew.

The crankset I have has the chainring spider swagged onto the crankarm. The more I look at this unit and the more I think about it, the more I wonder if it's even an Adamas AX crankset.

Cheers
