Does this fan have "sealled bearings" ?

I'm not sure about being sealed, but it is quiet and the one I have has been running for several months with no problem. I'm using it in my power supply.

I'm sorry I cannot answer this question. The fans are installed in the case and are working well.

Mine was quite noisy and I thought it had a bad bearing. Technical support told me to check the end of the pump that was perforated since it can be bumped and become cocked and lets the fan hit the housing. He told me to remove it to see if it helped. I could see that it wasn't sitting properly and moved it and it ran with just a hum of the motor turning. Was quite happy.

Yes they do have sealed bearings, this pedal is strong I am using everyday on my MTB and they rock!

From the Noctua FAQ:In order to ensure flawless operation over many years of usage, all Noctua fans come with a premium grade SSO bearing, which is fully sealed to prevent the entering of fine dust particles. Please note that the fan is not designed to be taken apart by the user. Removing the impeller from the frame will break the sealing of the bearing and results in a loss of warranty.

Yes, old motor pulled out with brackets and replacement motor slid back in with bracket and attached to fan housing. All this done on the roof.

yes, it does. or you can pull up the pin and the fan will stay in one position. Great fan.

Doesn't appear to be sealed. Doubt you will need to because fan is quiet compared to most fans.

No. It is fixed speed and of bad quality ... at least the one I got. ... After of 20 hours operation the unit started overheating and a bearing noise developed. The unit feels robust, but it's lifespan is questionable ... needs to be seen.

Not to my knowledge..it is installed in my living room...there are specific fans that state indoor/outdoor usage..their motors are self-contained from the elements.

No, the fan is self contained and very quiet. I did have to modify one of mine with a Drexel though, but they was due to a problem with the case, not the fan

No, it does not. Only the output seal, metal clips for pump, and snapring access plug. No bearings or bushings.

sealed bearings. along with a "greasert" fitting to lube if ever needed again. pretty fairly smooth and strong...

Not that I recall but you can just buy some small o-rings to do that. It is a very quiet and smooth fan for its size and airflow but made of a light plastic.

Yes it does, but can be turned off for scratch start. Cooling fan has excessive noise and runs all the time.

No. I had two of these fans and they are very noisy and fell apart within 6 months....the only saving "grace" was that I got them with my points I earned...

Yes they are, but don't buy this fan from Amazon. Mine was missing parts and Amazon never did make it right. :(

Just install these about two months ago. All seals and bearings are included. No guarantee that the bearings and seals will be installed. Only one of four had the bearings and seals installed w/grease.
