What Are Bearings? Let’s Learn About The Basic Functions Of Bearings

Do you know what “bearings” do, a mechanical part? They are so essential that the “bread and butter” of the machinery sector is a reference to them. Because of their often hidden nature, most people unfamiliar with the machine business might hear the name and need clarification about what it refers to.

This article aims to provide a quick introduction to NRS Bearings (ตลับลูกปืน LM Guide NRS, which is the term in Thai) and their uses.

What Are Bearings?

When anything rotates, bearings let it do so smoothly. They support the shaft that turns inside the machine.

Vehicles, aircraft, electrical generators, and other machines rely on bearings. They’re utilised in things like freezers, vacuums, and air conditioners that everyone uses regularly.

Bearings reduce friction and increase rotation efficiency in devices with moving parts such as wheels, gears, turbines, rotors, etc.

Bearings are the “bread and butter” of the machine business since they are utilised in virtually every type of machine due to the high number of shafts needed for rotation. Bearings may appear as inconsequential mechanical components, but humans need them to function.

Bearings’ Function: What Makes Them So Crucial?

Just how important are bearings to the efficient functioning of machines?

The two primary roles they play are as follows.

· Facilitate Spinning By Decreasing Friction

When a rotating shaft contacts its supporting component, friction is inevitable. Between these two parts, bearings are employed.

The bearings’ main purpose is to lessen the resistance to rotation. Because of this, less energy is required. This is the most crucial use for bearings.

· Keep The Shaft Properly Positioned While Protecting The Component That Holds It In Rotation

The force between the rotating shaft and the component that allows the shaft to rotate must be great. Bearings keep the spinning shaft in its proper position and protect the supporting component from the damaging effects of this force.

Bearings provide this purpose, and that’s why machines can be used repeatedly for so long.


Because of their relevance in our daily lives, bearings are continually subject to improvement efforts to increase their accuracy and longevity. Furthermore, developing bearings that can perform under ever harder and more specialised conditions is crucial to advancing machine technology. There is little doubt that bearings will continue to develop and advance, hence “making the world go round” and bettering our standard of living.
