2G OEM wheel bearing manufacturer

[jakelandry]

Does anyone have an OEM wheel bearing laying around they can inspect for part numbers? I only have access to aftermarket bearings which appear to be ntn hub111’s.

Just going off memory, but I thought the OEM bearings were made by Koyo.

I can get it for you tomorroe if someone dont get it sooner, i have bearings at work, i know it starts with DAC and it does not result in anything as i searched before for research. Koyo makes the oem bearings though

Why do you need this number btw?

Thanks for the help. I’d like to know if there are internal dimensional differences between the aftermarket bearings and oem.

The many i have taken apart no, they all based around the same specs since there is not alot of ability to alter it. The difference will be finished quality on surfaces, clearance specs (likely as close to oem) and ball bearing finishing

The dimension I am interested in is ball bearing diameter which I believe may be slightly smaller on an oem bearing in comparison to aftermarket.

Everyone i have looked at are all 1/2" balls or 12.7mm, for the fronts anyway, i have not looked at the rears in detail.

I have taken apart many units and alot are pattern parts / aftermarket versions and all have the same sized ball and race as oem. I have not opened every brand of course but thus far i have not seen any difference in ball size alone

Thank you for the help Bobby. Are those actual checked values or estimates?

Actual checked with a digital calipe.

Just one of the many bearings i collect. Some oem and some aftermarket and so far bearing size has not altered, but as i said i have not opened every brand.

A bit late to the game, but I have a full set of brand new mitsu hubs in my garage. Here is what I found on them:

Front: Koyo DACF1092A
Rear: NTN HUB111

Hope that helps.
