This is part of the issue that America will face going forward. To re-industrialize, we will need to re-create the entire manufacturing ecosystem.
Used to be that one could drop by any reasonably stocked hardware store and get some brushes to rebuild that noisy electric motor.
Can’t happen today.
Don’t even ask someone under thirty what are brushes doing in a motor. You’ll just get zombie eyes.
Its a fake. Read the comments on the youtube source.
The giveaway is that there is too much difference.
Maybe the Chinese mean theirs are for slingshots.
Calling bearings “the humblest of fruits” is an admission of ignorance. (For the record, I represent a number of patents for the Timken Company of Ohio in Europe, and the effort that goes into making quality bearings would astound you - or the author of that article, at least.)
BTW, that site runs dozens of scripts, which NoScript thankfully blocks for me, so I cannot view the video. Any direct link to the video? Thanks.
I’m sure the Chinese military is full of this sort of high quality equipment.
Saw an article in an American Society for Quality journal that places the level of quality in Chinese manufacturing as about where the US was in the 1980’s.
I’d like to know the viscosity of the oil on each bearing before I draw any conclusions. I don’t know what controls are in place to ensure a fair test.
Thanks much for turning me on to Schweinfurt. I Googled it and got a great history lesson.
The Germans were an amazing people. Seems like the first thing they did after getting bombed was to clean up and make the area orderly, as some kind of cultural imperative.
