Teflon bearings out of no longer working hard disk drives make great bearings

Dom
Are thinking of the fluid dynamic bearing use by Western Digital  ?
Problem here is availability of off the shelf components, so this would be a variant to the replication, correct?

How about a group buy of the machined parts from a place like eMachineshop.com?

Got my 1/4 * 1/4 * 1/4 cubes today. So marked them up and mounted in Rotor.

Now just waiting for the Stator Magnets.

I don't think so Bill, FDB are or would be fairly new,,,, 3 of the drives that I rippped them out of are 80 to 100gig, ibm, is definitely one of them, The main spindle bearing has the backing plate which you can unscrew of the drive and use the whole assembly as is on the magnet motor board, there's another bearing which is the read/write arm bearing....
Thats what i'll be using, ask for defective drives at your local pc supplier, you might be surprised they might come to your aid.

Harddrive bearings spin fairly well.

Wind down times are probably double now with all that weight at the outside. The rest of us are probably nearly as anxious as you are to get the rest of the magnets get in!!!

Well you guys dont know me from Adam, but I have been here watching for a looong time... I am extremely interested in this particular project, I have submitted the plans as kindly provided by Jason to my local machine shop friend... I have asked him to supply me a quote for 10 of the units... if there is any interest please let me know... I will post the cost each hopefully by the end of today. I am not sure how expensive it will be but will gladly send them at my cost plus shipping. Thanks

Hello Group
The time has come to seek a specification on the Stator bearings
In my Rep I will be hopefully using a bearing of the following specification.

Basic Spec.
ID - 0.25", OD - 0.5", Thk - .125 or Metric equivalent, *Free spin*
Material - 300(316) series Stainless
Application - Bearing going into a magnetic application, so needs to of the Non magnetic type, Operational speed in the order of 4K rpm
Have RFI 's out to various vendors and hope to here from them soon.
Note: I would prefer to have a flange type, but may have to settle for the standard shell.
Was interested in the bearing choices the other replicators are planning on incorporating because i feel this is an critical aspect of the device operation.
This is the reason for this Inquiry and Posting  ;D

Bill

For the Stator magnets, I believe that Al did not use nonmagnetic bearings. The fact that the bearings are magnetic may play a critical role in the motor's operation. We do not yet completely understand what components are necessary for the effect to work so I would suggest that you use the same type of bearings that Al used just to see the effect, and then replace them with non-magnetic ones later.

God Bless,
Jason O

I don't know the exact part number. He did mention the dimensions of the stator bearings though (which are noted in the blueprint drawings) and noted that he got most of them from Stewart-Warner. Beyond that, I don't know.

Jason
Excellent, Yes i new the dimensions, but not the manufacture. Will go chase it and see if i can come with more details. Actually planed on looking at both i.e. Chromium (magnetic) Non magnetic (SS).
But first have to get the device to operate.  ;D

Regards
Bill

Hi Unzapped.  I'm interested.  But it might depend on where you're located -- it probably wouldn't make sense to ship half way around the world.  (I'm in the U.S.)

Are you in the Uk?, anyway interested, depending on cost + shipping.

Has anyone sourced the other parts?, bearings, magnets for the Uk?, I have the link for the German magnet company, but would prefer somewhere in the Uk.
