What is bearing?

Bearing is “a part that helps an object rotate”, which is called "jikuuke" in Japanese. As the name suggests, bearings are the parts that support the "shaft" that rotates in the machine.

Machines that use bearings include cars, airplanes, generators, etc. Bearings are also used in household appliances such as refrigerators, vacuum cleaners, and air conditioners that are commonly used in our lives.

In these machines, bearings support the "shaft" on which parts such as wheels, gears, turbines, rotors, etc. are mounted, helping the shaft rotate smoothly.

Since many rotating "shafts" are used in various machines, bearings have become an indispensable part and are called "the food of the machinery industry." This part looks inconspicuous, but it is actually very important. Without bearing, we would not be able to live normally.
