Alright, I wasn't gonna bother responding when I saw this yesterday but it's been absolute AMATEUR HOUR with the responses so far. So!
Ball bearing mechanisms can come in many beautiful shapes an sizes, but they all share a common factor: the use of perfectly spherical balls that sit between two objects to stop them from scraping against each other. After all, you don't want chafing!
The classic ball bearing mechanism is cylindrical, allowing you to squeeze a shaft (called a bore) into the tight hole you want it to sit in. In this mechanism, you put your balls in a cage to hold them in place, thereby binding them tightly to the shaft. As the shaft rotates in one direction, the balls move the opposite direction to provide low-friction motion. However, because even smooth objects can stick together, it's important to make sure that your balls are properly lubricated before pressing them into the groove of your shaft.
It's important to choose the right lubrication, too! If your lubricant is too sticky it can cause things to stick together awkwardly, but if it's too thin for your application it could leak everywhere and make a mess! For tight, presurized systems, a special device is used. Simply squeeze the head of the device into the hole behind the balls and pump your desired lubricant right up into it. If this isn't practical, you can also use splash lubrication. In this case, the lubricant starts within the system and all the thrusting and rotating of the parts will make sure that everything is fully covered by the time it's done being used.
In general, ball bearings are classified by the type of load they like to take. For example, if your machine is going to be taking multiple kinds of load, you'll want a deep groove ball bearing. These provide extra protection to the balls and the shaft, adding flexibility and allowing it to take loads that might make a mess of other ball bearings. On the other hand, if you want to take a deep forceful load directly down the shaft, you'll need a thrust ball bearing. Thrust bearings are perfect for taking a nice heavy load, but lack the flexibility of some other ball bearings.
Hopefully this has been nice an informative!
