bearing shop, tat bearing can be use anywhere....
as long fits and work fine then ok d.....
u surprise lei, how much bike shop charge for certain things...
as i said bearing cheap no point, the main important is how u fix in or the installation process....
it can be very good bearing but do u know the bearing....
Bearing built for factory can last few hundreds yrs theoretically wit proper care...
Once u drop the bearing, the life span 20 to 30 yrs, then when installation bang bang another 20 or 30 yrs life span gone....
By right installation of bearing kenot have not bang or shock....
U need to kembang the crank case or bearing housing to fit, control hydraulic machine to press the machine....
for eg
bearing size for eg is 25mm, the crankcase maybe bigger by 25.025mm oni....
So now u c there a need to change the bearing of the original....
Added on March 15, 2012, 2:14 pmu think is cheap bcos u c the bearing as ENGINE bearing...
but the truth is bearing is still a bearing la....
imo it should be bearing size : 25mm, crank case 24.95mm, because the process should be heating up crank case, dryice bearing, and put into and it will fit nicely, no need other tooling, working engine will expand due to heat and bearing will still attach to the crank case nicely.
