Do you know what mechanical parts bearings are? They are called “food of mechanical industry” and are widely used in various important parts of machinery. Because these important parts work in an invisible place, they are usually not understood by non professionals. Many non mechanical professionals don’t know what bearings are.

What is a bearing?

Orientation is a part that helps an object rotate, known in Japanese as jikuke.As the name implies, a bearing is the part that supports the rotating “shaft” in the machine.

Machines that use bearings include automobiles, airplanes, generators and so on.Bearings are also used in household appliances such as refrigerators, vacuum cleaners and air conditioners.

In these machines, bearings support the “shaft” with mounted wheels, gears, turbines, rotors and other parts to help it spin smoothly.

As a result of various machines to use a lot of rotating “shaft”, so the bearing has become essential parts, known as the “machinery industry food.”This part may seem unimportant, but it is important.Without it, we can’t live a normal life.

Bearing function

Reduce friction and make rotation more stable

There must be friction between the rotating “shaft” and the rotating support member. Bearings are used between the rotating “shaft” and the rotating support part.

Bearings can reduce friction, make rotation more stable and reduce energy consumption. This is the biggest function of the bearing.

Protect the rotating support parts and keep the rotating “axis” in the correct position

There is a great force between the rotating “shaft” and the rotating support part. The bearing prevents the rotating support member from being damaged by this force and keeps the rotating “shaft” in the correct position.

It is precisely because of these functions of the bearing that we can reuse this machine for a long time.
