    applying just enough grease to hold the balls in the cup. Caster bearings are a about the cheapest form of ball bearings there are.
    Never try to tell me it can't be done

    This reminds me of garage door extension spring pulleys where the outer race is stamped sheet metal. The two halves are riveted either with pierced sheet metal that is staked, or real rivets. These have a life where they eventually pull apart from the cable tension. I made solid steel pulleys and used dual ball bearings as replacements were not as robust as the original pulleys. Last month, I just replaced the 4 extension springs as one failed and the others were about to. Always fun to fix one issue and then the next weak link fails.

    Just figured out why roller conveyor wheels are so economical...and plentiful
    At .03 and .05, manipulations of the cup, is the nozzle misting lube? Very efficient, versus oiling the balls would cause adhering to others. The intent is clear, but can't quite work out why cup on deck faces down. She clearly has them pre-staged in right hand, race side up. The post in bowl of bearings is surely pneumatic, but a pedal and lever would work too.
    I'm certain very nearby someone's pressing the other side on, making up tote bins of wheels. All the shipping fullfillment centers worldwide are using these by the thousands, not to mention what's used in general manufacturing.
    Sincerely,

    Explains why cheap bearings always seem to be sloppy with missing balls. I assume the grease doesn't always hold all the bearings.
