Superblend main bearings. Any issues?

I've read many posts about the poor quality of some variations of the FAG layshaft bearings.
My question is whether there have been similar issues with different renditions of the FAG superblend main bearings. By different renditions I mean year or country of manufacture etc.

Thanks,
Ed

Never seen a post complaining about an FAG superblend layshaft bearing except the requirement for shimming can cause some extra work, but plenty about the portuguese ball layshaft bearing failing which is the steel cage disintegrating allowing the balls to all go to one side and escape the bearing.

Any standard 6203 layshaft bearing can fail (due to the cage breaking up). Unfortunately, the Portuguese FAG 6203 bearings had brass cages which tend to break up more quickly.

Providing you buy from a reputable source, then no is the answer. They have been made in many places over the years, but if you see anyone selling new bearings made in England, Germany etc then be wary, they could be NOS, but I doubt it. There is also one plant that I'm aware of now making this spec of this bearing in the clearance we owners use and it's in India and owned by an Austrian company, so again no problem with quality.

The good news now is that the chances of getting a cheap copy are now remote, it is a bearing that is not in great demand elsewhere in industry in the spec we use, so not worth copying these days - most probably why there are no issues like you have read about other size bearings.

Be aware though that most bearings can also be obtained in non-automotive grades.
This means they are not rated for higher speeds or temps.
And should be cheaper as a result.

Can't 'superblends' be obtained with polyamide cages (plastics). ?
Previous discussion is that these are not as highly rated as brass cages, but still good.

Please correct me if my memory is not working correctly, but I seem to think that the "Superblend" layshaft bearing is a two piece roller with a Polymide cage.

For the gearbox yes it is plastic as the temps are low hence the milky oil you get from condensation, for the Engine main bearings the cage is brass because of the higher temps.
