Update Continental. They were bought by Schaeffler Technologies AG who also own INA, F.A.G. and LUK and are opening or have opened a factory in China and Russia.
Its possible the Conti pulley is using a INA bearing Made in their own Chinese factory if so that's fine but I suspect these will be more common in the European market.
The ones I have seen are not actually produced by Conti but the same company making them for other brands. Buying parts is a never ending research project to figure out if the part has changed since the last time you bought it or if its even still produced by the same company and not just a name.
Aisin is 30% owned by Toyota and OE on many Japanese cars, they have high quality and a stellar reputation. Conti and Gates may be an OE supplier but for the aftermarket they have a second quality line where Aisin does not.
I have bought new Aisin pumps that have had the Toyota or other manufacturers casting mark cleanly ground off. My opinion is if its not a brand name bearing or uses less bearings than OE in the the case of timing belt idlers (some aftermarket use single cage low quality bearings instead of double cage premium bearings) go with OE.
