Default I would use the teflon too.

ChristopherKee;

I'm going to order some Teflon sealed/shielded bearings today. How long did they take to arrive?

Actually I/we have 8 cars/trucks in the racing stable. The 4-5 that get brought to the track are:

1) My Reflex NT
2) My Pro-3
3) Stepsons Reflex NT
4) My 8 yr old Sons HPI Nitro-2
AND sometimes; 5) My HPI Super Nitro, 6) My Sons Tamiya TL01

There is ALWAYS 4 cars on race day and I'm the mechanic for ALL of them. That's how I came up with the Popsracer name. The Dad is always working on the Kids cars.

Ordered on a Wednesday, arrived on Monday US Mail. They don't give you shipping options. But it was less than $4 for shipping.

Interesting note I found on a skateboard related site from someone who claims to have worked in the bearing industry for several years:

Quote:
At my Company we brought in Chinese Bearings for .12 cents each! We had the stamping machines to mark the shields. We did PIG, GIRL, SPEED DEMONS, and several others. All were from the same manufacturing lot with different color/marked shields.
And related to SKF in particular:

Quote:
SKF Bearings are now manufactured in almost every country in the world. SKF no longer manufacturers miniature bearings and hasn’t for over 10 years -SKF contracts out their miniature bearings to the Miniature Bearing Manufacturers. Last year it was IKS and NTN. It could be someone different next year. SKF specializes in large bearings…. Don't use SKF.
I make no claims as to the validity of the above, just passing along what I found. The post was dated in September 2002 FWIW.

I just ordered some teflasonics from acer, had pretty good luck with them in the past, I also ordered some of their new dual super polymide sealed color bearings to try them out, with a name like that how can you go wrong.

Stay away from the blue seals on ebay, they are pretty cheap and tend to break apart after a short while and their pretty hard to "free" up. You pay for what you get.

Have you guys tried those X-ray or Tamiya blue seal bearings. They are really super smooth and the seal is super slippery.

Sometime before the ROAR Carpet Nats I'm going to order a bearing set. I haven't decided what yet, probably Acer, maybe ceramic if I can afford it then.

Sushi, I've got the blue seals in my XRay. They seem like a decent bearing, nothing spectacular though. Because of the size of all the xray bearings they last forever between cleanings. It's hard to tell if they really free the car up though, because as a whole I don't think the XRay is a very free drivetrain.

I use:

MIL STD Y-DxdxB

D is outer diameter
d is bore
B is width


the MIL STD is the type of bearing I use. Not sure if its in your catalogue or not but they are the best.

Well I recieved my bearing from Acer withing 3 days. Good service. The ceramic diff balls have definatly made the diffs in my xray smoother. No complaints here

I have not read this entire thread but this is my take on the bearing issues.

this is for onroad only- I buy the cheapest shielded (not sealed) bearings I can get my hands on. The last set I bought on ebay was like $12 for the entire car (tc3) I then put them in a Integy Indi sparkle that has been filled with motor cleaner and I let them shake rattle and roll for a couple of hours. Then I blow them out with some compressed air to get all the remaining grease out and re-clean them again for a couple of hours and blow them out again. I then use a light high quality bearing oil to reoil them. They really seem to last a very long time and when they go bad you are not out that much money. I see the shielded bearings on Ebay all the time otherwise you can get them from Boca for pretty cheap. By using these bearings I am able to keep my tc3 very freed up their is very little drag.

Default Got my Teflasonic bearings today

Guys;

Got the bearings from Acer racing today. Took 3 days total. I'm not going to degrease them yet, as i want to see if there is any difference when I do and they seem to have a very light grease in them now. They should give me exactly what I am looking for in a bearing.

Thanks for everyones input.
