  How many tribulations can it take to make a bearing ball?

  Although there are thousands of types of bearings, they all follow the same mechanical principles and mechanical laws. According to the different force transmission methods, bearings can be divided into two categories: sliding bearings and rolling bearings. The former depends on pushing conduction forces, and the latter depends on rolling conduction forces. Even if one's middle school physics is taught by a physical...
