I spray WD40 into my bearings- liberally and let the excess mung and chogies drip out on a newspaper laid out on the floor.  That gets is back to spinning every time.  But performance is degrading slightly each time.  Eventually, I'll have to take it apart and clean the bearings and maybe even take it to Chinatown and get the windings redone.  Hopefully, I'll be repatriating by then.

 

Sure it would help if you actually lubricated the bearings! WD40 is a solvent or rust destroyer! slowly but surely you will flush any oil or grease out of the bearings and they will be running very dry, as WD attracts rust bearings should be starting to make a nice squeaky sound by now!

I've got a 5 year old Hatari that would disagree with you.  I'd probably get 10 years out of it if I added grease or oil to the sintered bushings, but then the bushings would probably outlast the windings.  And by that time, the power cord will be brittle from age.  No use overdoing it.

 

Besides, my biggest problem isn't lack of lubrication.  It's the lint that contaminates the exposed lube.

 

I'm operating on the theory that the WD pulls a little more of the grease to the surface of the impregnated bushings.  If I'm wrong, so be it.  But so far, so good.

 

BTW, I absolutely agree on ball bearings.  For my fishing reels, I use the WD just to clean the bearings and sewing machine oil to lubricate the high speed bearings and petrolatum on the low speed ones.

If it works for you! can't knock it, there are always exceptions, surprised the bearing is not dry by now, not usual to put a lot of grease in em. After five years you have little to complain about, I usually hand them onto her family after a few years as they start rattling too much for me!

WD now make a silicone lubricant marketed here, ideal for gate rollers and the like. http://wd40thailand.com/wd-40-specialist-silicone-lubricant-size-360-ml

Why is everyone still going on about bearing and bushes that need lubing ???
The problem is that the electrical motor is partially shorting out which explains why the fan is turning slowly, and the only two ways of fixing it is
:1 Replace the electrical motor - may as well buy a new Fan !!
:2 Have the electrical motor rewound - Buy a new Fan !!
