If yer want a deep groove ball race that will last get FAG bearings..
the numbers of the bearing will be either 62XX or 63XX..
read the number off the bearing go get a good brand with that number..
how bearing numbers work...
6 = deep groove ball race.
2 or 3 = bearing OD - usaly 2 ODs in each bore size.. a few have 3 sizes "4"
XX = bore size ---- 02=15mm / 03=17mm / 04=20mm / 05=25mm
So a 25mm ID bearing will be either...
6205 ...52mm OD x 25mm ID // 6305 ..62mm OD x 25mm ID // 6405...80mm OD x 25mm ID..
