The bearing fits perfectly and has exactly the right dimensions. It seems to be of good quality and fulfills its role perfectly. We'll see over time.... I've already bought very high-end stainless steel bearings (36€), but the body is steel and only the balls are stainless steel. I haven't gained anything in lifespan, so I now take bearings with a good quality/price ratio.
