NSK was the first company to empolder mute rolling beaing of autocar inner used electric motor.

 

As the development of autocar inner equipment, customers have more and more high requset to the mute of inner air condition. Commonly, electric motor of vehicular air-condition uses sliding bearing, but in order to achieve mute purpose, rolling bearing will be instead of sliding bearing. This time, NSK not only apply flexibly mute technic which developed the electric motor before, but also empolder producing technic of rising cleanliness, thereby mute purpose of vehicular air-condition’s electric bearing has a high improvement. We can say that it has a large technological content.

 

The design of products is very innovative. The cage of bearing is new developed. Because the cage’s turning reaches the most suitable, so the noise can be prevented in the condition of low temperature. At the same time, the intreface of seal’s lubricity has the high quality to prevent the spirant. NSK empolders the producted technic to rise cleanliness, which reduce the noise that due to the dust to smallest.

 

This kind of bearings’ selling aim is one billion and five hundred million yen in the world at 2008. NSK bearings’ successful development and marketable investment will bring the evolution of whole industry.
