NSK pioneer developed the car using motor mute rolling bearing
As the vehicle interior equipment constantly updated and improved, The market customers ask higher and higher requirements on car air conditioning mute. In general situation, vehicle blower motor using nsk bearing is sliding bearing, but to achieve the mute effect, the nsk rolling bearing will replace nsk sliding bearing. NSK not only use the mute technology which used in previous developed motor bearing, but also developed a new manufacturing technology which can improve cleanliness class, so that the vehicle blower motor bearing the mute effect is great improved. It can be say with high science and technology.
This product style is very new, nsk bearing retainer shape is new developed style, due to make the retainer to the most suitable operation, thereby preventing the noise of retainers produced in low-temperature conditions. At the same time, the lubricity of seal ring contact surface is improved, thus preventing the friction sound. In order to suppress the trace of dust in bearing, NSK developed cleanliness improving manufacturing technology, make the noise caused by dust almost be zero.
