The word “bearing” incorporates the meaning of “to bear,” in the sense of “to support,” and “to carry a burden.” This refers to the fact that bearings support and carry the burden of revolving axles.

The basic function of bearings:

1. Machinery will run more efficiently
2. There will be less frictional wear, extending the operating life of the machinery
3. Preventing abrasion burn, avoiding mechanical breakdown
Bearings also contribute to lower energy consumption by reducing friction and allowing the efficient
transmission of power. This is just one way in which bearings are environmentally friendly.

A surprisingly large number of bearings can be found all around us. Take automobiles, for example: there are 100 to 150 bearings in a typical car. Without bearings, the wheels would rattle, the transmission gear teeth wouldn’t be able to mesh, and the car wouldn’t run smoothly.

Bearings enhance the functionality of machinery and help to save energy. Bearings do their work silently, in tough environments, hidden in machinery where we can’t see them. Nevertheless, bearings are crucial for the stable operation of machinery and for ensuring its top performance.
