Why Are Bearings Important? The Functions of Bearings


How exactly do bearings ensure the smooth operation of machinery? They serve two crucial functions.

How exactly do bearings ensure the smooth operation of machinery? They have two primary functions.

≪Function 1≫ Reducing Friction for Smoother Rotation Friction inevitably occurs between a rotating "shaft" and its supporting rotating part. Bearings are placed between the rotating "shaft" and the supporting rotating part.

Bearings reduce friction, enabling smoother rotation and minimizing energy consumption. This is one of the key functions of bearings.

≪Function 2≫ Protecting the Supporting Rotating Part and Maintaining the Shaft in the Correct Position

Substantial forces are exerted between the rotating "shaft" and its supporting rotating part. Bearings prevent damage to the supporting rotating part caused by these forces and keep the rotating "shaft" in the correct position.

Thanks to these functions of bearings, we can repeatedly use machinery over extended periods.
