This edition of the series of programs explaining the technology used to produce items that are familiar in our daily life features ‘Steel Balls’. A bicycle wheel spins smoothly because the wheel axle contains ball bearings. The steel balls inside the ball bearing must be close to perfectly spherical. The program introduces the production method of high-precision steel balls with a margin of error of less than 0.1 micrometers.

      June 19th 2019 now if the ball bearings for our military in the United States is made in America but under Barack Obama's administration Joe biden's administration they were made in communist China. Inferior steel. Rolling thunder 4 million-dollar Abram battle tank got stuck because the ball bearings melted. The embedded chips from communist China that is why 13 aircraft carriers were put into port to change the chip technology from the Communist Chinese to American chips. Computer chips. Now this platform was made in 2015 why continue to purchase products in communist China when they have slave labor to boot I boycott any product that uses ball bearings and slave communist labor.

      Well done. Clear, concise good video, excellent slomo and explantion. The only problem which all you tubers do is they have garish and distracting titles at the intro. I think as this medium matures, more professional graphic designers will get involved.

      To make bearings you need a machine that has bearings in it (paradox i think, maybe)
