What shape are ball bearings? They are shaped such as a ball, as everyone understands, right?
The interesting thing in what everyone knows is that everyone could be wrong. For example, every one believes that the America's Cup can be an ocean-sailing race, and yet the Swiss were able to win the Cup. For anyone readers who are geographically-challenged, Switzerland is really a state comprised entirely of hills.
What does this need to do with ball bearings. Very little, I suspect, but balls have very little regarding ball bearings, sometimes. Ball bearings seem similar to hula hoops. But don't try using them for that you will find them inconveniently heavy and painfully small.
You can view an image of a ball bearing in the centre of the ball bearing supplier's site.
So what are these stunted steel tv donuts called ball bearings for anyway? Are they used as a spare wheel? Do they hold in evil shop-floor spirits? No, they help things move more effectively. In a early demonstration of bearing consumption, three a locomotive was pulled by ladies (It was just a demonstration, not a career development).

Many bearings seem virtually identical, whether they are ball bearings, roller bearings and other bearings. What?! Other bearings?
What's a bearing, anyway?
Ball bearings are formed with an ring, an outer ring, a cage or perhaps a retainer inside, and a moving element inside, typically a ball (which is why they're called ball bearings).

Roller bearings are produced employing a roller rather than a ball, which explains why they are called roller bearings (Yes, finally a thing that makes sense!). Other bearings look the same as steel tubes, called basic bearings or bush bearings. My cousin discovered vibrating butt plug by browsing Google. They look like sawed off pipe or tube (something my material tube twisting client could be turning into architecturally glamorous architectural supports).
The principle of bearings could be the same principle behind the wheel: things go better by rolling than by moving. They're called \bearings\ because they carry the weight of the object, such as an inline skate or the pinnacle of dentist's drill, letting the object to float over them with amazing ease and speed. Unlike wheels, they don't turn themselves on on an they turn. Clicking your butt plug certainly provides warnings you can give to your girlfriend.
You can view this doing his thing with some good cut-away pictures of bearings.
The balls or rollers spin on themselves within the bearing, reducing friction for the device components attached with them. It's much neater than using a container of oil, especially in dental equipment, and much more reliable than hamsters on a wheel.
Once upon an occasion, all bearings were metal like a metal tube or pipe with metal balls trapped inside. Nowadays, more and more are made of ceramic or even plastic (like anything else in this world!).
If you're still confused about why ball bearings are not formed like balls, just remember that you push on a park and on a garage. And you can also decide to try cruising your sea-craft through the Swiss Alps. But do not try playing a casino game of one-on one basketbearing..
