I personally think niftech sells the best bearings. A buddy of mine ordered a whole set for his tc3 and man what a differnce they made. You could push the car with no pinion on the motor and it seemed like it would roll forever. Twice as far as my xxx-s does. And talk about better straight away speed.The only down fall is they are kind of expensive.

Niftech is the king of selling the same product you can get from others for 4x to 5x the price. The Niftech bearings (metal shielded) and the Acer are the exact same (my opinion). I have both for my Losi dif and down to the balls and pressing they are the same. Acer price $1.46 per bearing, Niftech $7.95. That is just lude-ah-cris...


With Acer having all thier bearings on sale right now.. it's the best deal in town.

Where I work, we get a military aerospace bearing catalogue so it has many more variables printed in it than the general catalogue.

stuff like thermal expansion at 40C and 100C etc is in it, whereas that would not be in the general catalogue.

You will probably have the same bearing just it won't have been tested as thoroughly which for RC use is not a problem as it brings the cost down!

As I said before, there are only a handful of people who make the bearings, the rest of the guys out there are like Computer Manufacturers, they by the OEM spec stuff, put it together and sell it. SKF, Timken etc are like the intels and AMD's of the bearing world. They make the bearings in the first place.

hello imataquito,

I got to know from schumacer that you're ordering some ceramic bearings from skf.. do they have it?? I did call skf malaysia office in sentul and one of their engineer called me and told me that the bearing need to be ordered from usa... he also told me that he is in rc too... but nitro... but he don't have the price yet.. maybe your contact person has more infomation....

BTW, I am actually looking for bearings with ceramic balls for my pro 3.... if affordable, I was thinkin to replace the whole sets of it... anyway, where actually your location??? I used to play in Subang SS19... you?? maybe we know each other but I dont recognise your username... if you do know me... drop me a line...maybe we can order the bearing together to save a bit...



regards..

dexter

Hey there... Spongebob and popsracer!

What do y'all think of your new bearings (teflon and polyamide)?

I'm especially curious about the polyamide ones... what on earth are they like?

jwwu;

First race with them this Saturday. Probably won't be able to tell at first until the grease gets spread around inside them.

Just got my bearings in the mail today. The new polymide seem to be a little more free then the teflon without doing anything to them. The seals are a transparent red but they come in other colors for different sizes. Without running them they seem like really nice bearings, teflon or polymide. I'll try to get a picture for ya.
