Bearing for an idler roller

Bearing for an idler roller
I've scored a used roller with bearing NSK 6203-DUL1B with some bearing noise. So I pressed bearing out and pulled the seals:
Old original bearing (left) with black dusty grease; KBC replacement bearing on the right (overfilled with grease)
The original bearing contained some black grease mixed with very fine dust (source of the noise) I could not find specks for it (maximum RPM and dynamic load limits)
So far I've found 2 replacement bearings:
One is Korean made KBC
Dynamic load, lbs 2,100
Maximum Speed 12,000 rpm
Lubricant Grease (unspecified)
Temperature Range -20° to 230° F
ABEC Rating ABEC-1
And second one is SKF (Made in Argentina):
Don't cry for me Argentina
This bearing has better designed seal lip which will prevent dust from getting in so I used SKF

What's idler roller? Is it the idler pulley bearing for the serpentine belt? If so I'm very much interested. I changed the transmission input shaft bearing with a honda bearing and I regret it a bit. It's a little noisy again. I wished I'd used a higher quality bearing than the OEM because it seems they are prone to failure.
How much is the bearing? I believe the replacement idler for serpentine from Gates is like 15$.

Yes this is an idler roller for the belt. The bearing is about $10 from Grainger (bough it a while ago). The seal design of original bearing was not capable of stopping the very fine dust from getting inside on the donor car; I'm expecting the same about my car as well.
