Why is it important? The function of bearings


Summary: To ensure smooth machine operation, what exactly is the role of bearings? It has two main functions. Function 1: Reduce friction and enable smoother rotation

What is the role of bearings in ensuring smooth machine operation?
Bearings have two main functions.

≪Function 1≫  Reduce friction and enable smoother rotation
Friction is inevitable between a rotating "shaft" and its support. Bearings are placed between the rotating "shaft" and its support.
Bearings reduce friction, resulting in smoother rotation and reduced energy consumption. This is the function of a bearing.

≪Function 2≫ Protect the rotating support and keep the rotating "shaft" in the correct position
Significant forces are exerted between the rotating "shaft" and its support. Bearings prevent damage to the rotating support from these forces and keep the rotating "shaft" in its correct position.
It is because of these functions of bearings that we can use machines repeatedly for extended periods.
