Comparison of bearings
The network has a video, which compares two simple bearings. Their difference is only in the manufacturer – the first is made in China, the second – in Germany. Both are advertised as having “weapon quality”, however German costs 30 times more.

Is there any difference, is it worth overpaying? An unknown Chinese engineer tried to show the difference with an elementary test. Watch the video:

Test 1: Chinese bearing. Makes several revolutions around the axis and stops. The rotation time is about two seconds.

Test 2: German bearing. Rotates, rotates and rotates. The time to stop is 27 seconds.

As they say, you saw everything yourself.
