My first use after 100 flights this oil removed much fine dust from my 4250 1010w motor i removed the excess oil using a cotton bud the motor is quieter now and i drip and dab at the end of a days flying HTH
to add on to noddyflyer, some motors like emax or gws motor don't require you to disassemble the motor if you can see the front and rear bearings.
just screw on the applicator tip (needle-like-thing) that came with the oil, squeeze of a drop on the bearing, rotate 3-10 rounds, repeat 3 times... should give you good oil penetration
Sealed bearings do not need to be relubricated when the operating temperature does not exceed 60-70 °C and the rotational speed is below 50 of the limiting speed listed by the manufacturer. When temperature and/or speeds are high, relubrication is recommended
but is is sealed, how can you get with the oil inside of the bearings ? Maybe is the sealant part will get damaged, because of high speed and temperature, you probably will have also the grease melted and sloped from the bearings.
The Bearings are not sealed, have a look at the lubrication around the shaft and housing Most Brushless Electric motors running at these incredible RPM'S, chuck out all factory lubrication in a very short time and run very dry, makes the problem of lubrication very important, unless you replace origional bearings with Boco Ceramic equivalents, this oil is possibly the best alternative available today and its compisition bonds itself to the balls running at extremely high temperature elimating bearing failure My experience with Heli Motors re-Lube every 6 Flights Planes about 10 depending how hard you push your model, Good Flying.
No, That's its Brand name, I can only parrot what's printed in the package = Mfg in the USA, Its a specially formulated oil to chemically bond to the balls and races, enabling it to cling to the parts under the highest loads,
It has worked for me as I have had several bearing failures in very expensive Align 600 Electric Helicopter motors running on 12S, the bearings run beyond Mfg spec's, they still chuck the lubrication out, but don't run dry anymore. Hope that helps. Kevin.
It stinks that brushless motor bearings aren't sealed. This is the first I've even thought of oiling them, and I've never heard anyone else that I fly with recommend it either, though I agree, the last time I took a HK motor apart, the bearings were definitely not sealed. No wonder there are so many reports of bad bearings.
