Those are not actually the right size. A couple of the numbers are mixed up!

You want something like these (thanks kloner from another thread)

Stainless keeps them from rusting. every model i've bought in the last 5 years was full of em.

I wish a par of $7.50 bearings were the price of a replacement motor. The $7.50 is shipped, so a pair is $15. i've bought 3 dji motors seperately now, they were $41.03 to my door.

Also found shafts that fit at twisted hobby under replacement shafts for 70g outrunners, but they have to be cut to fit. theres also no flat spot but there 4mm and have the c clip ring cut, using one in a dji motor right now

Wait, are there 2 bearings in each motor? O_O

It's hard being a noob...

in these, yes. the suppo motors i'm putting on mine soon have 3, and there bigger diameter
