The roller bearings is around us everywhere in nowadays life.

Cars running in the morning lights, hoods immersed in the aroma of food, hair dryers bathed in the fragrance of shampoo... All this is closely related to bearings, which are called "food for machinery industry".

The bearing is a "part that helps an object turn". As the name suggests, bearings are parts that support the "shaft" that rotates in a machine. Bearings can be seen everywhere in modern daily life. In these machines, bearings are responsible for supporting the "shaft" with wheels, gears, turbines, rotors and other parts to help the shaft rotate smoothly. 

Bearing is a kind of component in contemporary machinery. Is widely used in the machinery industry, strict requirements of accessories and basic parts, is a variety of mechanical rotation axis or movable parts of the supporting elements, but also rely on the rolling of the rolling body to achieve the host rotation of the supporting elements.

Bearings are usually composed of inner ring, outer ring, rolling body, cage and grease. 

The inner ring usually fits closely with the shaft and rotates with it. The outer ring is usually matched with the bearing seat hole or the shell of mechanical parts to support. But in some applications, there are also outer ring rotation, inner ring fixed, or both inner and outer ring rotation.

With roller cage evenly arranged between the inner ring and outer ring. Its shape size and quantity directly affect the bearing capacity and performance. Cage will even separated, roller guide roller movement in the right orbit, internal load distribution and improve the bearing lubrication performance. Grease is used in the friction parts of machinery for lubrication and sealing. It is also used on metal surfaces to fill gaps and prevent rust. 

In order to make the machine run smoothly, what role do bearings play?

First, bearings can reduce friction and make rotation smoother. Rotating shaft and support part will be friction. Bearing used in rotating "axis" and support between parts. Bearing can reduce friction, rotate more smoothly, reduce energy consumption. This is bearing the biggest role. Second, protect the rotation support part so that the "axis" of rotation is kept in the correct position. Between rotating "axis" and support parts will suffer a great force. Bearing can prevent damage of revolving support part due to the force, spin "axis" in the right place.

Bearing in widespread use in life have a lot of bearings. With the continuous development of mechanical technology, more can adapt to the harsh environment of the special new type of bearing will be constantly develop applied to our daily life in the future. Bearing will continue to develop and progress, for our life to continue to "operate"!
