Not a bad video!
I noticed you mentioned more than once that the bearings were actually bushings,m and you even said "I don't know why they call them bearings?" You have come across the most commonly wrongly referred to piece in the mechanical world, lol!
They call them bearings because...they are bearings.
Those round brass, or steel or plastic things we all call bushings, are not, they are what is called a "Plain Bearing".
An actual bushing is something that does nothing more than take up space. If you put a bolt in something, and the bolt is too long and won't get tight so you throw a washer in it to fix that...that washer is now a bushing! A bushing is also used to join two parts, like a pipe bushing....it is still serving the same purpose, filling the gap between the 2 pipes or fitting.
Anything that is made to reduce the friction of movement is a bearing!
That little part inside of a heim joint that the bolt goes through...that's a bearing too!
Even though technically incorrect,It is not necessarily wrong to refer to a plain bearing as a bushing . It has actually been mis-used so commonly for so long that about every defining source (I.E. Dictionary's pedia's, etc) includes the definition of a plain bearing as a type of bushing!
Now you know....and Knowing is half the battle!
GO JOE!
