T47 bottom bracket 86mm for shimano

[Strappacatena]

Hi guys, I need some help. When I built my Long Teng GV201, I used a ZTTO T47 bottom bracket, but it only lasted a year.
​Does anyone have suggestions for a good T47 bottom bracket that won't break the bank?
​Thanks!

You can buy any bottom bracket. just knock the old bearings out and replace by a set of ntn, skf or other qualitative bearing brand.
