Japan Seiko (NSK) play the long-term accumulation of tapered roller bearing design experience, analytical techniques, have developed 4th generation of highly efficient tapered roller bearings. The new products will be listed in the year 2012, the NSK goal is to 2016, make two billion yen in annual sales. Areas of tapered roller bearings are widely used in cars need high support rigidity and load manual gearbox, automatic transmission, differential gear mechanism. Therefore, in order to improve fuel efficiency, it is necessary to further reduce the friction loss of tapered roller bearings. The depth of the teeth at both ends of drum through the increase of the inner ring and the outer ring raceway surface, and reduce the load of the ends, to reduce the frictional force at the same time, the life and the support rigidity of the previous item is equal to or higher than the level of. The drum-shaped teeth prior processed into a cylindrical shape, and the rotating surface to be able to withstand a certain load the roller and the inner and outer rings, slightly deformed state, to achieve the envisaged shape. As a precondition to deepen the drum-shaped teeth, and the number of roller length, the contact angle and do change accordingly. Thus, the decrease in the friction losses of the new product by 30%, the durability is also extended to approximately 1.5 times. The advantage of this margin, also to achieve the miniaturization of the bearing. And can also be used for the site of the ball bearing used in the past.
