5. Bearings 101 Bearing Types and Numbering System:

Kirosawa this is not. But what this video lacks in slick looks, it makes up for in content. Emerson Bearing Co. President Steve Katz explains numbering systems and shows examples of more than 15 types of bearings.

At over 10 minutes, this is the longest video on our list, but it’s well worth the time.
As an added bonus, you get Katz’s incredibly mellow voice—this is the Bob Ross of bearing talk.
