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 angular contact ball bearings and inner and outer ring ball contact point of the connection at an angle with the radial. Contact angle is generally divided into 15 °, 30 °, 40 °, respectively, with the letters C, A, B said NSK special production contact angle of 25 ° of such bearings, said A5.

Angular contact ball bearing ball contact with the inner and outer ring at an angle with the radial. Contact angle is generally divided into 15 °, 30 °, 40 °, respectively, with the letters C, A, B said NSK special production contact angle of 25 ° of such bearings, said A5. Angular contact ball bearings mainly bear a larger one-way axial load, the greater the contact angle, the greater the load capacity. Cage materials are steel, brass or engineering plastics, molding methods are stamping or turning, depending on the bearing form or use of different conditions and use. There are other combinations of angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings .

Angular contact ball bearings can withstand both radial and axial load. Can work at higher speed. The larger the contact angle , the higher the axial bearing capacity. High-precision and high-speed bearings are usually 15 degrees contact angle. In the axial force , the contact angle will increase. Single row angular contact ball bearings can only bear one direction of axial load, radial load will cause additional axial force. And can only limit the axial displacement of the shaft or the housing in one direction. If the pair of double-mounted, so that the outer ring of a pair of bearings relative to the wide end face wide end face, narrow end face narrow end face. This avoids additional axial forces and limits the shaft or housing to axial play in both directions .

Angular contact ball bearings because of their inner and outer ring raceway can have a relative displacement in the horizontal axis, so you can simultaneously bear radial load and axial load - Joint load (single row angular contact ball bearings can only bear one-way axial load, So often used in pairs to install). Cage materials are brass, synthetic resin, etc., according to the bearing form, the use of conditions and distinction.

There are: 7000C type (α = 15 °), 7000AC type (α = 25 °) and 7000B (α = 40 °) several types. This type of bearing lock on the outer ring, the general inner and outer rings can not be separated, can withstand radial and axial joint load and axial load in one direction. The ability to withstand axial load by the contact angle , the contact angle is large, the ability to withstand axial load high. This type of bearing can limit the axial displacement of the shaft or housing in one direction.
