So you want a Chinese Spindle !!!!

[diyengineer]

Went to the bearing shop.

Front 2 Bearings:
Double pack spindle high speed bearings. Chinese replacements $240.00

Japanese (top of the line) replacements $410 dollars.

Either way, the bearings cost more then the spindle. They have the best prices around, unless you live in a communist country cough cough *china*.

I did have the bearings checked and he said there was minimal runout, which was probably to spec for being a chinese bearing, he said it shouldnt affect anything in day to day operation and they looked healthy. The rear bearing i did not even get a quote on since the front 2 were so expensive.

I dont have a VFD or i would re assemble it and see how she operates.

If the front bearing pair are in good shape, get a tube of Kluber and repack them. The single rear bearing might not be too expensive to replace. If the front bearings are preloaded, you could probably replace it with a deep groove bearing. Check out VXB for prices.

I will give them a ring. I would imagine though it would be far more money since they don't have hundreds of thousands of square feet of warehouse and monster purchasing power, all focused on just bearings. But it is a shot.

I will probably repack the bearings like mentioned and reassemble.

Where can i pick up the Kluber? Is this something like auto zone would carry, or do i have to travel back to the bearing shop.

[ger21]

Bring your wallet. We use some that's $300/quart.

Anything short of 300 bucks i can use? lol

[steveg]

I believe that these are an equivalent bearing http://www.vxb.com/page/bearings/PROD/Kit10873
Kluber NBU15 (correct choice )can be bought herehttps://www.klubershop.com/ for around $30 for a little tube
Back bearing (assuming 7003C)http://www.vxb.com/page/bearings/PROD/Kit10828

PS did you find the outer race yet ?

Out of curiosity(caused be you guys, darn you!) I took the back cover
off my rummi/love 1.5Kw spindle it has a NSK japan bearing

Sorry to have been so sparse on the details about the Kluber. I thought that I had seen you following Hoss' G0704 thread. There had been a discussion about it there. Anyway steveg pointed you in the right direction...

Also http://www.cnccookbook.com/ has an article dated 4/27/10 called "Kluber's Magic Spindle Bearing Grease".

Dear Mr. eloid ,


Thanks you, still we do not know this seller ,we saw the so called SGS certificate on ebay
( http://cgi.ebay.ca/3KW-WATER-COOLED-...item56315ba70c ),
clearly that's not the original certificate .They should have made it by themselves...ISO certificate is not just a page file.(over 10 pages ).

I've not quite followed everything said here...
But it's not unheard of, or even unusual, for a reputable mfg to outsource to China and the actual facility which handles mfg pulls a "third shift" to make copies of the same design to sell on the side.

However, they may not be able to procure needed parts produced outside the factory, esp ones produced outside the country. In which case you could indeed have a unit with identical housing, armature, ports, terminals, etc, but cheap Chinese bearings because the company which contracted the work won't send them 8,000 sets of German bearings for a 5,000 unit order. And they lack the know-how and German-speakers to procure them- also it may arouse suspicion. It's easier and more profitable to substitute a locally produced part at drastically reduced cost.

Or the company may have anticipated this and simply asked for them to ship the housing and armature for a final assembly done elsewhere with bearings they never saw. So they really don't know what goes in it and just fitted what they could find.

these spindle are made manufacted in china.... and imported here to 3 parties sellers.

not the case here , they make low end model ... and other models with german bearing key is to know who you dealing with.....

If the manufacture or ebay seller do not provide you with some type of docummention... almost 99% of the time there hiding or missleading the buyer.... why...
manufactures who do not stamp mark there logo name or model number on spindle tend to sell there spindle to trader and 3 party vendors who mark up the cost, and dont want to provide you any traceable info on the product, ie support or parts.... consumable spindles.....

If you ask the right questions and deal with the "manufacture" you find out several things, you get detail info on product ie bearing, and you learn that most spindle come with 2 year warrenty not one as claimed by ebay sellers
that why most exchange unit with no hassle!!!!!!!!!...But your get short changed buy 1 year in warenty.





And they lack the know-how and German-speakers to procure them- also it may arouse suspicion. It's easier and more profitable to substitute a locally produced part at drastically reduced cost.

it all about cost,,,,, if they can sell you a german look alike... they will.

these unit are made china 100% ...some will offer nsk, fag3 bearings
but you need to inquire.. and ask the right questions
questions...

[lgalla]

If you are getting a Chinese spindle with Fag,NSK or Thk bearings,they are manfactured in China.All the bearing companys have been in China for the last 10 years or more.I have THK BK/BF ballscrew support bearings and the bearings came in a package marked Made in China.The problem is you will never know if you received German or Jap bearings made in china or local copies.Don't think for a moment that specked with German bearings that they were made and shipped fron Germany.Only time will tell.A dollar rubber stamp is all that is needed to make a skate board 20cent bearing into a 100 dollar bearing
