Flanged bearings for the axles.

[Rad_Schuhart]

Hi all. I know that a common upgrade is to install bearings in the motor axles, so it gives some rigidity to the hull. I've seen some tank shops that sells that kind of upgrades but they are pretty expensive for what they are, and drilling in the hull is needed.

After finding the flanged bearings I wondered myself if we could install them on a tamiya tank, like this bushing upgrade: https://www.axels-modellbau-shop.de/kat ... ssing.html

So my question is do you know what size of bearings can we install in a tamiya tanks? Can somebody give me the dimensions in mm? I have a couple of tamiya tanks (A Sherman and a king tiger) but for now I dont want to remove/damage the sprochet plastic caps that I superglued sometime ago until I know if the dimension needed exists.

Roughly I think the inner bearing size is 8mm and the outside is 13mm, but I might be wrong, so an exact size would be apreciated!.
Thanks!
