Castle Mamba Monster bearings

[nuz69]

Hello,

I wanted to get some opinions about castle bearing maintenance.

Some people here say (Europe), that its not good to drop some lubricant in them, because it's create an abrasive dough with the dust and can reduce bearing life time.

The bearings seem to be damp-proof, therefore i think that no maintenance is required. I have runned my 2200 kV motor during ~40 batteries, and the bearing still look great with no resistance when i rotate the motor.

Maybe the Castle staff can confirm this ?

Thx
