Kingsong S18 Repair - Replace EUC Bearing / Grinding Noise

In this video I'd share the way I replaced my Kingsong S18 bearings. The bearings apparently start to produce some grinding noise. Turns out it caused by rusty ball inside the bearing.
I replaced mine with NTN 6203ZZCM which has zinc cover rather than rubber seal used on original S18. But you could use any other bearing as long as it coded 6203. Look for it's datasheet if those bearing could support your weight.
This is only the way I've done it. If you want to follow it Do It at Your Own Risks. If I done something wrong or mislead information, do send me your thought in the comment.

as an electric motor mechanic and rewinder... NEVER use a shielded bearing on these electric unicycles!!! The double sealed 6203LL was much better as it's sealed!! That shielded bearing will last maybe 1/4 as much as the sealed one it had.

i would regreese those bearings with vacuum method with some marine grease. As rotation speed is not so fast, bearings should be full of grease, not half of them.

I used 2 claw hammers to gently prize the disc cover plate off, more controlled

Поставил не герметичный подшипник .Нужно 6202-2rs с пластиковым пыльником.

definetly not ZZ bearings should be used, 2RS only
