where do you guys purchase your ball bearings

[E-Revonut]

I need to get some bearings myself, for my Tekno Neu. What would be the best? I know they're 5x13x4. Should I go ceramic? Abec 5 is better than 3 right?

I purchase my bearings from VBX.com, which is one of the main suppliers for a lot of the R/C dealers. They have a pretty good supply with fair pricing, and they even do kits for a lof of R/C models. Plus I usually get the sealed steel shielded bearing for loner life. Rubber and plastic shields will melt if you get them hot enough.

For very high revs, you need a bearing with small tolerances, so ABEC 5 is better than 3. The ceramic balls will have less drag.
Engine and motors are two of few applications where I would NOT use 0.99$ bearings.


Jerry, if they are steel shielded, they are not really sealed. If you want rubber shields that can handle high revs, you need non-contact rubber seals. These are often used in front engine bearings, along with low-friction cages and high-temperature grease.

I have had five different specifications of 5x10x4 mm bearings (for clutches) from the same manufacturer, and different they were.
