Hi guys

After a bad crash I damaged a couple of Pacer 2207.5. One of them don't spin at all, the other one seems to spin but with lot of noise and interruptions. The bells seems to be both undamaged.

I would like to replace bearings.

Now i'm asking you... which bearings should i use ? Where can i find them ?

The motors are these:

Thank you!

According to spec, they are 9*4*4 NMB bearing. So that sounds correct. 9mm overall diameter. 4mm center. 4mm height. But it seems that when you are looking for bearings, they are labeling it 4*9*4. I am not sure which nomanclature is correct. Just double check that the dimensions I wrote above is correct. I wanted to add that you are getting flangeless bearings.

Thank you very much for your help!

What do you mean for flangeless bearings?

These ones are ok ?

Hi guys,

I'm replying to this old topic because it's now time to fix those motors.

I will purchase some 684ZZ 4x9x4 bearings but I've got an additional question for you... which ABEC should I prefer? I know that higher ABEC has tighter tolerances but are more subject to dirt and dust... any idea?

I will probably not buy NMB bearings because of the price... i will buy some high rated bearings from aliexpress.

Thank you in advance.

I am using these bearings and they fit 4 by 9 by 4.
A dollar a bearing.
