NSK Bearings through the "MOTION & CONTROL" (operation and control) technology, in order to build a comfortable and safe community dedication. While safeguarding the global environment, we should strengthen our solidarity and cooperation among nations, people and people through undertakings in the world.

Japan's Seiko Co., Ltd. (NSKLTD) was established in 1916, Japan is the country's first design and production of bearings manufacturers. For decades, NSK has developed countless new bearings to meet the needs of users all over the world, and has made great contributions to industrial development and technological progress. At the same time NSK relies on its technical advantages in precision machining to continuously develop high, refined and advanced products such as auto parts and precision mechanical components and actively carry out diversified operations in the field of electronic applications.

Gradually establish and perfect the trinity business system with production as the core, technology as guidance and marketing information as an aid. NSK will speed up the localization of this system so as to provide more direct and complete services for the vast number of users in China. China's industrial modernization make its due contribution.

NSK tapered roller bearings are separate bearings, bearing the inner and outer rings are tapered raceway. This type of bearing according to the number of rollers installed into single row, double row and four row tapered roller bearings and other different types of structures. Single row tapered roller bearings can withstand radial load and single direction axial load. When the bearing is subjected to a radial load, an axial force component will be generated, so when another bearing that can withstand the axial force in the opposite direction is required for balancing purposes.

 

Tapered roller bearings are mainly subjected to radial-based diameter, axial joint load. Bearing capacity depends on the outer ring raceway angle, the greater the angle bearingThe greater the carrying capacity. This type of bearing is a separate bearing, according to the number of rolling bearings in the column is divided into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance users need to be adjusted during installation; double row and four row tapered roller bearing clearance has been given in the factory according to user requirements, without user adjustment.

 

Tapered roller bearings have a tapered inner ring and outer raceway, tapered roller arranged in between. The projection lines of all conical surfaces meet at the same point on the axis of the bearing. This design makes tapered roller bearings are particularly suitable for composite (radial and axial) load . Axial load bearing capacity is mostly determined by the contact angle α; α angle, the higher the axial load capacity. The magnitude of the angle is expressed by the coefficient of calculation e; the larger the value of e, the larger the contact angle, the greater the applicability of the bearing to axial loads.

 

Tapered roller bearings are usually separable, that is , a tapered inner ring assembly consisting of an inner ring with a roller and a cage assembly can be installed separately from the outer cone (outer ring).

 

Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.
