Possible reason for the prevalence of foreign rather US made bearings these days.

Totally discounted, or a totally bogus. [http://www.raspberrypi.org/archives/tag/ce-compliance]
LOL, those were the expensive Chinese ones!
I bought a pair of them for $5.23 shipped.

For a low voltage application like the driver board 'E-Stop' I'm not too worried about the bogus certification, just that they work (which they do).

The bearing thing is pretty disgusting, I was told by a major American manufacturer that they were no longer producing one of the bearings that we use and to buy chinese. I then waited 10 months while they were on the slow boat from china, shaft collars were 11 months. Order early. Shaft collars are a simple item.....
I did not say that they didn't conform to CE standards, what I did say is that the CE is self declared and as such _may not_ meet the CE standards. I'm from Ontario, I went through all of this with the inspection authority, it is NOT recognized as sufficient to have components marked with the CE symbol to pass a CSA inspection. The inspection service is a recognized service in the US though they do have to be approved in each state and in my discussions with I was told that the same holds true in the US, the CE mark is NOT a recognized approval. Here's a link to the Ontario Electrical Code, you might not agree with it but in Canada anyway, that's just the way it is. http://www.google.ca/url?sa=t&rct=j&q=ce csa certification recognize&source=web&cd=5&ved=0CFQQFjAE&url=http://www.esasafe.com/pdf/Sample_Bulletins/2-7-29.pdf&ei=gDW-ULnDINL02wXvpoHwDg&usg=AFQjCNHFcuszwP7xxpvvN0aXoyhmmo0ixQ
I'd be rather suspect of that site anyway, they are misusing a comparative image of two similar logos as below from the CE Wiki.
"China Export
The difference between the CE logo and alleged "China Export" mark.
A very similar CE marking has been alleged to stand for China Export because some Chinese manufacturers apply it to their products.[SUP][10][/SUP] However, the European Commission says that this is a misconception. The matter was raised at the European Parliament in 2008.[SUP][11][/SUP] The Commission responded that it was unaware of the existence of any "Chinese Export" mark and that, in its view, the incorrect application of the CE marking on products was unrelated to incorrect depictions of the symbol, although both practices took place. It is in the process of trade-marking the logo and it is in discussion with Chinese authorities to ensure compliance with European standards"
Just because it's in the internet doesn't mean it's true.

Are many CNC machines used in the manufacture of a ball bearing? From what little I have seen about how the balls and races are ground and polished, its kind of a setup intensive operation for each size, class etc. Maybe there is a newer CNC ish way of making them?
Also I second the niche market comment. We just shelled out $1500 for a rather odd roller bearing setup that has two center races fused eccentrically to create walking action in two plates. OD is about 4 inches so the margin on that unit is quite nice for someone.

As I understand it, when the large american manufacturers started closing down, while a lot of the tooling and equipment was just sold for scrap, much of the really specialized machinery was sold at pennies on the dollar to Korea, China, Taiwan, India etc. and they now make a tidy sum selling us items that we no longer have the equipment, knowledge, or inclination to manufacture for ourselves.
Their idea of economics is very different to ours. What little business is left here seems to be more concerned with creative accounting than anything else.

It is easy to blame the workers, and some of them are slugs. But the real culprit is the overhead costs. When i started out working where i am at now 40 years ago, our group had one secretary and one superintendent. That was the only non working persons in the whole group. + or minus 200 persons. Even our foremen are working foreman. Now we have 6 safety men, dozens of secretaries and payroll people, engineers, purchasing people, people to fill out forms, rules, regulation and who knows what else. And do not forget the training classes, again and again the same junk. OSHA, NIOSH, EPA, HAZMAT, HAZWOPER, RATT, MOC, ISO, JUST FOR STARTERS. It is to the point now that my company must charge twice as much per hour than the total package that the workers get. For every ten dollars i get, ten dollars are wasted killing trees and filling out papers. 90 percent of which are a total waste. In my little part of the group we have two superintendents, 4 big foremen, 4 little foremen, 4 geologists, three technicians, 9 engineers, one safety person, and four workers that actually do the work. Now tell me how it is the workers fault. America is full of people who can not do their own jobs but are experts on telling others how they should do things. Especially things that they have no idea how to do,even if their life depended on it. Yah you worker should be ashamed for wanting more than minimum wage,
This is very true, but then how would we employ everyone if they did not come up with more red tape and beauracracy (sp)? YEP, the non-workers do outnumber the workers and I get to keep less and less of my dollar and somehow if we manage to save some, there is some new trick developed to relieve us of it, like the upcoming,,,,,,,sorry, remember the rules NXr, No Politics!
