Machines that use bearings include automobiles, airplanes, electric generators and so on. They are even used in household appliances that we all use every day, such as refrigerators, vacuum cleaners and air-conditioners. Bearings support the rotating shafts of the wheels, gears, turbines, rotors, etc.

What is bearing and its uses?

The main purpose of bearings is to prevent direct metal to metal contact between two elements that are in relative motion. This prevents friction, heat generation and ultimately, the wear and tear of parts. It also reduces energy consumption as sliding motion is replaced with low friction rolling.

Where are bearings used in cars?

Bearings enhance the performance of the vehicles, bear heavy loads, and reduce friction. Some major sub-systems where bearings are used are engines, gearboxes, transmissions, wheels, steering, electrical motors, pumps etc.
