Default how to get bearings super smooth?

hi there,

i am trying to make a couple of hub bearings from a losi 8ight that will go in a spare hub and i will try and use as a balancer. i tried it before but the bearings where giving incorrect readings.

but how do you get the bearings super smooth and spin long?

they are rubber shielded and i found this video:

is this a good way of getting bearings super smooth?

if there is a different way you are welcome to comment.

many thanks

lewis

Remove the rubber seals and clean out all the grease and dirt, do not re-grease them. There will be less rolling resistance without the grease giving you a more accurate reading.

As 'Reeltech' said, remove the shields and grease. Run them dry...

I used to use this method and still found that it wasn't always accurate. I finally purchased the following...

http://www3.towerhobbies.com/cgi-bin...&I=LXD712&P=SM

Since then, I haven't looked back. This thing works perfectly! I just used an extra hub and nut to secure the wheel/tire and go from there. It's saved so much headache.

If you need help setting it up, PM me and I'll send you pics of mine.

boy i dont know i woulnt remmend running bearings with just bearing oil in them on a 1/8 now you can use a little systec red mobil 1 gresse just a little bit but eventually you will have to buy new bearings anyways.


now on a 1/10 to me its not a big deal to run them dry or just light bearing oil because they arent as powerfull and lighter.

Read the first post, they will be used as a tire balancer. That being said, the Dubro balancer is much more accurate. I tried putting the Mobil 1 grease in my bearings but it doesn't help and the grease flings off after a run anyways. Better off buying new bearings for $1 each when they start to get gritty.

Is all you really need. 2 drinking glasses of the same height, place shaft on rim and place on top of the glasses.


But yea, a Dubro is a nice thing to have.

I said yes as it works.What i was meanin is i had a losi with gritty bearings and it made them super smooth when they were really gritty, but they dont make them last forever. I know he was talking about a balancer but i wasjust staighting it works fine.

thanks for the help, i will try that this afternoon but if it doesn't work then i am getting the losi balancer.

also my dad reckons that if i take the shields off and clean it out but leave the shields off then they will run better, is this true?

many thanks

lewis

Yes it will be smoother,thatís what I did with my fishing reel bearings and I really noticed the difference.
But the reel bearings were in a enclosed case,where the RC car will have dust flying around and the bearings will have a shorter life than having shields.
