Ball Bearing Explosion!

ercoerco Posts: 18,498
Way OT for Fathers everywhere: Who knew that a hardened ball bearing would EXPLODE with fiery sparks in a hydraulic press? Just watch from 40-60 seconds.

"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you."

  • Fun stuff, wouldn't mind having a press with that capability, to waste some time now and then.
  • On another forum, someone said "If I had a press like that, I wouldn't ever get outside again".
    Re-inventing the wheel is not a waste of time if, when you are done, you understand why it is round.

  • Brilliant channel. Note the brilliant "Finnish rally driver English accent" as it's known in Finland.
  • Couldn't believe how far into the pusher that bearing went before going super nova. That Timkin steel must be extremely hard.

    Do not look directly into laser with remaining good eye...
  • Ball bearings are very dangeroose and can explode at any time, we must deal with it.
  • Gotta love it when an immovable object meets an irresistible force. This is particularly impressive due to the rate at which energy is applied to the system... Adiabatic compression of hardened steel...

    A Savage Model 10 muzzleloader can accelerate a 240 grain sabotted projectile to 2500 fps. It is tempting to find a rock quarry and rig a remote-controlled test where a hardened steel slug is fired at a large hardened steel block. 3000 Joules released in a few microseconds is a lot of Watts. Wonder if that would produce a pyrophoric reaction?

    For turning me onto the Hydraulic Press Channel, it's the least I could do!

  • Check out the paper that explodes after trying to fold it 7 times under the press.

    That's pronounced hoodrolic press.

    That and the hockey puck. It's amazing the amount of energy released when a material finally gives up and fails catastrophically.

    I'm still amazed how a golf ball deforms under dynamic loads.

  • The wife's laughter in the backgound is at least half the fun.
  • Well, did you ever open a golf ball? It's just a big knot of elastic band.

    Older ones, yes. (Likely the ball seen here is of that construction.) But all modern balls, at least those that I have disassembled, are no longer of a wound construction, and don't seem to compress when hit as much as the one in erco's video.

  • I lived near a driving range as a kid, and picked up many a ball in the surrounding woods, we would take them apart for a super ball inside, not all of them had it.

    It sounds like a Cinderella story here in Augusta!

  • A scanning electron microscope is almost as interesting as a hydraulic press.

    I think the golf ball video above isn't a real golf ball - it's either a faked video or the ball is a special one made of soft material.

    There are lots of other YouTube videos of golf balls being hit/deformed and none show those extreme levels of deformation.

    I agree, a real golf ball distorted that much would have split. Most likely it is a rubber ball.
