2200 bearing

[nuz69]

The answer is in your post... You must not lubricate or try to clean this bearing, by doing this you risk to damage the shieling of the bearing and to put the dirt inside, which result in a balls damage and death of the bearing...
The bearing is dualshielded so it don't need lubrication or maintenance.
My CC 2200kV has already seen 213 batteries of 3000mAh, and the front bearing is still in perfect health, although I never try to dirt it off.
You will know it for the future.

I replaced the bearing with new one but the same failure happened again, I didn’t perform any kind of maintenance this time.

I suspect that the front cover of the motor might have something to do with it.
After the 1st bearing failures I replaced the front cover with new a cover from Castle (got it with Rotor under warranty). I compared the cover I got from Castle to my old cover and found out that there is a different with the bearing housing. The bearing housing on the new cover is thinner and has more room for bearing play.
Look at the picture below, the cover on the left is the one I got from Castle.

Wow, 2 times front bearing ??? You are total unlucky man, sorry for you :(
The second bearing fail after how many batteries ? They suppose to hold a lot of time... Did you use the new rotor ? Maybe your first rotor is unbalanced, and do a lot of vibrations, resulting in the bearing failure.
Moreover, the bearing is suppose to be glued in the end bell to avoid the play you mentioned...
Anyway the 2 accidents are maybe linked, maybe steel of the pinion get in the bearing, is your pinion prematurely used or ?? You are doomed ...
Contact Castle support, their are very reactive and will take car of you. Good luck.

The bearings are not glued in, they are slip fit. I just replaced mine in my 2200 after 1 year of service... might have just been the wrong bearing at the wrong time...

There are glued stock. After ~100 batteries the glue does'nt hold anymore. You have to reglue it ^^

The day I got my 2200 It was not glued :)

as long as the rotor is shimmed correctly, you dont need to glue the bearings.

I think you are wrong. When my bearing unglued itself alone, I noticed some play in my front bearing and a strange noise of vibration, like the bearing moving in the housing.
Then I opened my motor and glued again the bearing in the endbell ==> no more play of the bearing in the housing, and no more strange noise, the motor just rotated quiet.
==> I think that if the bearing is not glued, it use prematuraly the housing, no matter the rotor shimming.
