I`m not BBBB but i`d say use grease, why ? cus that what its for and WD40 isn`t grease and is just for freeing shit up and such like so it won`t hang around long on your bearings and after a whatever, let`s say a few days, cus we can, but it`s not gonna be long before those bearings are gonna be running without anything like grease on so not a good fix, where as bearing grease or even vaseline which i used to use on my bikes for bearings will be around slipping "n" a sliding those bearing around for time. :)

 

Thanks for taking the time to reply pal. I think that there might be a slight misunderstanding going on. I feel that my bearings (metal shielded) are fine and there is no play so i am not going to be attempting to lubricate the bearings as they are perfectly OK. What I was concerned about was the spindle that the motor sits and revolves on, I believe it was not lubricated from the factory but my concern was having washed it (with good old hot water, fairy washing up liquid and some elbow motion) would possibly leave it susceptible to some rust however having left it to dry thoroughly I am going to just re-assemble it "dry" tomorrow.

 

Being born 1970 I had all the fun of growing up witht he first wave of skateboards, BMX and roller skates, the rule was that Dad would show us how to maintain our "toys" and after that it was down to us. The amount of bearings that got stripped down to the ball bearings washed in petrol and then re-packed in grease I cannot count, I still have my Dad's imperial sized (about 2.5 Liters) of (and it just soulnds SOOOOO wrong) Man Hole Grease! Once again thanks for responding 'scoops.

i wouldnt be using grease, its wet, and shi*t just sticks to it.

if you can find graphite spray, use that, its kinda dry and works well, if not use wd40, its not bad at silencing things

sorry mate i dont know the size of the circlip on the 6 inch fan, but i reckon it shouldnt be hard to measure with some vernier calipers/guage.

 

cheers

 

Thanks for taking the time to reply appreciate it. I don't think I explained myself to well. Having washed the housing and black fan section (with the motor removed) I was concerned about rust on the spindle/shaft and housing area where the motor sits, probably best to apply some WD-40 to a tissue and give it a gentle but thorough wipe over. I'm guessing the spindle?shaft would not need to be greased because of the way that the bearing s work. As kids we never greased the axles of the trucks on the skateboards or roller skates that the bearings were mounted on.  As far as the circlip I stripped down and cleaned a 6" A1 and the clip is the same size so I have one to match it up to if I need to go and find one at the local hardware store. Once again thanks for taking the time.

Evening all, just a quick update now I have my head off of Planet Stupid. I have given up looking for the missing circlip, went to a couple of local stores to no avail. Using the bearing codes that you posted for us I crossed referenced them with bearing boys website which said that they had an internal diameter of 8mm (to fit an 8mm shaft). Ordered and awaiting delivery of a pack of 10 for the fantastic price of £1.42 including free postage, I see why you feel how you do about simplybearings, the cheeky monkeys wanted £2.95 excl VAT for 2!

That made me chuckle. Luckily there were no other reasons other than that all the internals of these fans were filthy especially as some had been used without filters as part of the air cooled lighting system I run. For every ones knowledge fans that are used in this application should push the cooler air rather than pull the hot air, leaving them prone to collecting a lot of dust if not using at least a homemade filter made up of a couple of layers of old net curtains.

 

I am very much like that with old items because I feel that a component could potentially fix a damaged item at another point. For example if I needed to replace, lets see, erm A CIRCLIP!

I just ordered 20 x 608zz bearing from Amazon yesterday for £8.97 (ABEC 9 industry standard top frictionless quality) and they turned up a couple of hours ago.

 

My RVK150mmL1 has been wailing for a while now. I bought the new bearings in case that was the problem but it seems that when I cleaned it last I put the circlip under the spring washer instead of ontop, resulting in the circlip eating itself, luckily I have 9 left from the previous maintenance work.

 

So just sharing this FYI.

***EDIT***

 

I now have it wired up and fitted back in situ but it is making a terrible racket. I have left it plugged into the mains soclet so it runs at 100%, hopefully it will quieten down in a while and just needs to bed in.

Instead if editing my post above I have written this here so people see.

 

The link above for the Amazon 20pcs og 608ZZ DO NOT PURCHASE!

 

The internal diameter is slightly to large causing the dreadful vibration that I experienced, it sounded like a fighter jet trying to take off last night. This morning I re-fitted the original bearings there,  was no play on the spindle a runs a lot quieter.
