LUK dont make bearings, they make automotive driveline parts.
INA are FAG's (not FAK) sister company and also make bearings. Also look into SKF.
I can't advise you because of who I work for, it would be unfair, but I hope the name corrections help your search somewhat.
If by quality you mean "lifespan", SKF and I think INA/FAG have a bearing calculator on their websites which given some parameters will recomend bearings based on size, speed, lifespan etc.
