Rated 3.5 out of 5 by 48 reviewers.
Rated 4 out of 5 by Good Does what it's meant to do. And at a great CRC price. Seems to be tougher than my previous Alivio bottom bracket. The spline didn't round off at all when installing. However my Alivio one rounded off badly as the installation tool slipped often. 28 June 2014
Rated 5 out of 5 by price !!! cheap but effective if u wanna have less weight buy slx but if u don't care get this 15 June 2014
Rated 1 out of 5 by Very poor! This came with my Shimano deore crankset and hadn't even done 100 miles on it before it started creaking. I have taken it out today and all of the bearing are really rough. Its only a cheap BB, but expected it to last longer than that! 08 June 2014
Rated 4 out of 5 by great throw away bb I use these bbs for am fast xc trail all conditions they are great for a tenner and have lasted me longer pound for pound than the top brands if you don't mind changing them evry 5-6 months.. solid shimano kit.. 27 May 2014
Rated 2 out of 5 by Cheap but won't last long Bearing failed on left hand side. Lasted much less well than other, old style bottom brackets. 03 May 2014
Rated 5 out of 5 by Well worth the money The last one of these lasted 3 years so heres to another 3 with this one. 17 April 2014
Rated 3 out of 5 by Good value for money I have had this BB for 2 bikes now, both ridden primarily in wet / muddy conditions. One BB lasted 9 months the other lasted 6 months but for the price of the product I cannot complain especially as I don't clean my bike very often. 17 April 2014
Rated 5 out of 5 by Great value Inexpensive, easy to fit and works well. Last one lasted just over 6500 miles, used in all weathers. 15 April 2014

Answer: 
The 'Shimano BB51 Deore Bottom Bracket' would use the Hollow 24mm Style of axle found on the likes of the following listed Chainset's;

If you were looking to order a new Chainset the versions listed would also be supplied with a new Bottom Bracket similar to the Shimano BB51 so, you wouldn't need to order one separately.

Answers

Answer: 
While the FSA MegaExo is essentially the same as the Shimano Hollowtech system, they are not listed as cross compatible; FSA Cranks are matched to specific bottom brackets; the SL-K cranks require the BB-8000 series, such as the BB-8681 linked below

and in case it is not, which BB should I order?
sorry for bothering, I'm 99% sure it is compatible but as I'm ordering from BRAZIL I'd rather be 100% sure!

Answers

Answer: 
This marking bares no significance to the fitment of the bottom bracket cups and likely is a manufacturing process code.

As long as the spacing required is also of 68/73mm for a HollowTech II crankset then this bottom bracket will be fine.

Нет. Вам придётся менять и шатуны тоже. К тому же нужно будет торцевать кареточный узел. Эта каретка не имеет своего вала, т.к. рассчитана на систему с интегрированным валом (это когда вал интегрирован в паук, т.е. в левый шатун, на котором закреплены звезды).
