Alan at Hacked Gadgets found this neat video that shows how ball bearings are made. All of that work to make what seems like a simple part! [via Hacked Gadgets]

  1. There are lots of kinds of threads. Rolled threads, ground threads, die cut threads, lathe turned threads etc. The easiest way is to run stock through a die, which you can do manually. The most difficult is grinding, which is used for hard materials or precision fit. Threaded fasteners look simple but should not be taken for granted!
    Thanks for the great video.
    My wife is watching this now. She’s taking a break from designing a machine. She’s the one person I know with the most knowledge about bearings, bushings and automated machines.

  2. I replace pool/spa pump bearings all the time, usually the wet end had a leaking seal which leaked onto and took out the front bearing. The bad bearings can scream, seize or just sound like a metalic ‘whir’. They are held onto the armature/casing by ‘c’ clip, warped spring bushings or mostly just pressed into place. With new bearings the old rusty pump motor sounds brand new. Often the noisy old bearings feel/rotate ALMOST as smooth & tight as the new bearings… those tolerences have to be so precise to have such a quiet preformance in the motor!

  3. How it’s made is my favourite show. They have everything from plasma TV’s to hand-made musical instruments.

    I’m surprised this seems like a novelty here, don’t you get it in the US?
