You need 6805 or 61805 which are 37x25x7mm
The letters after rs,2rs,z,zz,DDU etc refer to different seal types 2rs would be fine .
Note the original raceface type bearings are full compliment meaning they do not include a race thus inviting play and a place for grit n grime to settle , avoid full compliment bearings!
Upgrade to some quality SKF made ones.
Also maybe worthwhile actually using the hope bearings ...these have an inside diameter of 24mm thus doing away with the crappy plastic bushes needed as standard.
There were also other 24mm i/d bearings available Enduro?
Oh another point! Look for deep groove types , these are better for accepting axial loads than the shallow groove versions.
Hope this helps .

You can get 24mm cartridge bearings whereby the inside race of the bearing is in contact with the 24mm crank spindle, thereby eliminating the fragile plastic tophat. You can source these from http://www.enduroforkseals.com. Look for MR 2437 bearings - they come in various grades, from ABEC 3 up to ceramic. They also sell complete BB kits, which are worth a look if you want to upgrade from a X-Type.0
