6384 bearing size

Build, Repair & Mod

Would anyone be able to confirm the bearing sizes in a Saite 6384? Looking to order some ceramics in advance of it arriving. Thanks!

6800 10x19x5, three per motor
Foil Drive are using 2 ceramic and one stainless steel in the Gen2. Anyone know where they use the stainless one?

Sorry. Not saite.
Apparently Jonathan you are correct. They are all the same size.

I’ve found the ceramic bearings from Ali work fine.

You will need two of the small one
6800
and one of the larger one.
6900

I have a cheap 6374 from aliexp, and it has two 6800 and a 6900.

Sounds like the Saite 6384 has three of the 6800.

All the ceramic bearings I tried failed very quickly. Saite does not recommend using ceramic bearings for 12s voltage.

If the bearings are failing quickly, is there any reason why you can fill up the whole stator with 10x bearings to help spread the load?

Alignment over such a short distance shouldn’t be too much concern.

Are these SS ok?

316 stainless would be preferable to 440C

Currently I am using SUS304 bearings. I’m not saying that all ceramic bearings are bad, but so far I haven’t come across a reliable one.

Sorry, but I don’t quite understand what 10x bearings mean.

The last bearing closest to prop is stainless on the gen 2.

13

I use the ones from Kugellager express on a saite 63100. They need to be changed every 300-400km. No rust, they just wear out.

I updated the above post with links to SUS304

15

sat_be are you using them in saltwater?

Not regularly, only occasionally, when on holidays. I also tried hybrid ceramic bearibgs but I prefer the stainless steel ones, they have less play and last longer.

After 3 sessions with the flipsky 6384 motor
One ceramic bearing failed the small one ref 61800 => very noisy
I will replace the 3 bearings with NSK stainless steel bearings

X1 W61900-2RS1

Where you removing the rotor for rinsing or just leaving it and the circlip on?
