Question about Kadee trucks

Hi folks !
I have a question about Kadee roller bearing trucks. Are they any different than the rest of kadee sprung trucks in terms of mechanics ? Is there really roller-bearing in them ? The fellow at LHS isn’t sure and I want to order about 20 of them to upgrade my rolling stock.

Thanks !

I dont know anything about that but, welcome to trains.com!

Thanks !
I’ve actually just found out myself. Called Kadee and gentlemen explained to me everything in detail. Turns out they just have truck shape a bit different, there is no actual ball bearing in it.

BTW, I see that Kadee trucks are not that popular in HO hobby. I wonder why ? They are pretty much the only sprung trucks out there.

I prefer rigid side-frame trucks, particularly Atlas’ when equipped with .088" semi-scale wheelsets (if your in HO scale). I use them and they are about the most free-rolling trucks in the world! But seriously, you’ll be happy with Atlas trucks.
