I assume you're on about the old type with the 350w cylindrical motor?
Don't really know about fitment on these but:
The only other ones I've come across is this for the old X2

This for the newer SX2

I got lucky with mine. My X2 clone (Osaki). It got damaged on the MT3, couldn't order a replacement. So looked at the Sealey version and ordered theirs and when it came turned out to be R8. I already have a belt drive fitted with the gears removed and it went straight in. Much better taper. It does look exactly the same as the one in the top link. It does require a new bottom bearing too as the spindle is wider (size35x62x14mm)
If you have no belt drive and are using the gears there's no chance it'll fit unless you can get the complete conversion set:

Just spotted they do the belt conversion pulleys separate, handy to know for me
Can't use the spindle from a SX2 on the X2 as it only has a top shaft size of 28mm.
I did notice the other week though that Amadeal do a belt conversion for a machine of theirs which is 28mm bore but the motor one is 10mm not 9mm.
I would say the belt conversion from Amadeal, a SX2 (28mm top) spindle and the small size motor pulley from LMS would all fit together too but all that will come at cost.
If you have the belt drive I'd take a punt on the arc one

and order the bottom bearing along with it.

If you have the gears still in they'll need taking out.
