The roller bearing dates to at least 40 BC, and it was applied to pulley blocks sometime in the dim past of history. There is probably no way to know when someone first put a roller bearing into a pulley block.

Why does water drain?
Water drains for the same reason that it doesn't stack. Picture water and other fluids as being made of very slippery small ball bearings. When you put them into a can or other container they take its shape. The top layer of bearings is flat, no piles of bearings anywhere (Technically this is called having a low angle of repose) If you make a hole at the bottom of the container which s bigger than several of the ball bearings they all run out. If you pour the container of ball bearings on the floor they don't make a pile but scatter until the whole floor is covered. The scattering isn't random, the bearings head downhill, even f the gradient is very small,and accumulate in the lower parts of the room first. If the water molecules could be quizzed they'd indicate that that, as a group, their goal in life is to be as flat as possible and as low as possible. So now lets think of water in a tub. When you pull out the stopper there is a hole that the water molecules can pass through easily. It allows them to be pulled by the force of gravity downwards and away they go!
