    Km/h are used to define the speed of a point but with a bearing you want to mesure the rotation speed. For that, pls use RPM or rad/s, that's more apropriate.

    Not only that, but the calculation of the circumference given in the video is also wrong. Instead of π 3.41 was used. This would result in a circumference speed of 216.4km/h Edit: also the same speed is assumed for every bearing independent of it's radius.

    Worst than that... Rotational speeds needs to be expressed in RPM. Even tho, the peripheral speed increase a lot with small radius increase due to 2piR expression. Smaller one withstand the rotational speed because its peripheral speed is way lower than her sisters with a bigger radius, si it even heats up a lot less due to less "motion" that causes friction and subsequent failure of the "beans". If u calculate the distance the biggest bearing runned in 15 secs and compare it with the distance the smaller one did, I'm quite confident that the biggest one had won even standing the mere 15 seconds...

    4:59 - I feel this 50mm one failed prematurely and it wasn't the bearings that failed, it was your design flaw of having the hex diver opposite to the locking tabs which locked the center hub in place. As you applied pressure with the drill you pushed the locking ring out. If the tabs were on the same side as the hex driver, it would have lasted longer, but I think the bearings would have piled up quickly anyway. But in a way, the 50mm didn't fail the test, (even though it likely would have), you failed it. Another of the rings came apart this way as well.

    Pretty nice job on the print quality. You however should've held the drill in the vise and hold the bearings in your hand. The unstable wobbling of your arm made the tests fail earlier than necessary.

    All bearings use some kind of lubrication, in this case a lightweight molybdenum grease would have made all these bearings last significantly longer, also for those that came to say he drilled it on an angle, it doesn't matter because the type of bearing he printed is meant to support some angular loading and ball bearing isn't designed to receive any, also his drive mechanism was poor but it did ensure if drilled too angled or pushed to hard it would just fall out, so it was fair. Do a grease vs no grease comparison plz

    I think part of the problem is that there doesn’t appear to be lubricant in the bearings. Keep in mind even metal bearings use lubricant and this kind of stress is beyond the scope of “straight from the printer” projects. I would suggest a wax as it’s less likely to react to different types of plastics compared to WD-40.

    Es un test muy subjetivo, para que fuera un test realmente objetivo, se debería haber hecho un soporte para los taladros. Tal y como él hace los test´s, la duración de los rodamientos creo que depende más de la inclinación y la presión que ejerce con los taladros que con la velocidad que soportan los rodamientos. Aún así, gran video!

    bearings don't appear to have gone through any process to smooth out layer lines, no lubrication, normal people test bearings by rpm not by km/h, and the rotational speeds given are a very rough estimate at best since they were assuming no load.

    Yes it can. Just make good design, use better suited materials (maybe nylon, or clear pla, i don't know), use higher tolerances, lubricate it, mount it properly - i mean not in 1 point with strange forces applied by hand. But you already know all of this.

    not good but not bad, for a more accurate test you need a balanced way to spin the bearing so that it doesn't create friction in one spot or more and also lubrication is needed so it doesn't create over heating and frictionless spin. but it was a goods test to see how a bearing would act if no lubrication and un balanced spin would act noting it is plastic and metal bearings would heat up and shatter but still I see what you were going for gg

  • @burggerbig102
    @burggerbig1027 ай бұрын

    It's not very accurate when you use your hand to hold down the drill. That has introduced way too many uncertainties. Typically the outer and inner parts of the ball bearings are fixed along the same axis. However, having your hand holding the drill would shift the inner rotation axis away from the outer bearing axis

  • @Bini.D
    @Bini.D2 жыл бұрын

    The bearings are not lubricated at all, and there are so many balls that they interfere with each other, so the balls bounce in the opposite direction. So, TPU bearings with high friction do not work well, and in that state, only one side of the bearing is fixed, and a vertical load is applied to the center shaft compared to the driving direction, which increases the potential for problems. Therefore, it is necessary to add a lubricant such as silicone grease and perform a driving test with a normal load applied to the bearing. And the number of revolutions (rpm) is a simple speed per hour and the calculation should not match. It may be problematic to request a retry for a video that is already 5 months old, but I would recommend that you try the bearing test again as requested by the subscriber.
