类型:NSK Bearings

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.

Ball Screw Introduction:

Ball screw vice is the rotary motion into linear motion, or linear motion into rotary motion of the ideal product. Ball screw by the screw, nut, reverse device and ball components, ball screw function is to transform the rotary motion into linear motion, or the torque is converted to axial force, both high precision, reversibility And efficient features.

Ball screw pair features:

Ball screw pair has the characteristics of high precision, reversibility and high efficiency, which is the further extension and development of trapezoidal screw, the significance of this development is to slide the action of the lead screw into a rolling action. Due to its small frictional resistance, ball screw bearings are widely used in a variety of industrial equipment and precision instruments.

Use of ball screw pair:

Ball screw pair to meet a variety of purposes, providing a wide range of standardized products. Circulation of the ball cycle catheter, circulator, end cover. Pre-pressure pre-positioning method (double nut, pre-pressure mode), constant pressure preload. According to the purpose of choosing the right type. Precision ball screw with precision grinding (accuracy is divided into seven grades from CO-C10) and high-precision cold-rolled cold-rolled ball screw forming process (accuracy is divided into 3 from C-C10 A grade, only a very small number can be done). In addition, to cope with the urgent need for delivery, there are finished products that have been machined on the shaft ends, semi-finished products and cold-rolled ball screw bearings that are free to chase the shaft ends. As the bearing peripheral components, the use of the necessary screw support unit, nut holder, lock nut, etc. have also been standardized, for the user to choose to use.

Ball screw pair is based on the accumulated product technology over the years, from materials, thermal management, manufacturing, inspection to shipping, are managed by a strict quality assurance system, so with high reliability.

(1) double push a free way? Screw end fixed end free. Fixed-end bearings bear both axial and radial forces. This support for the short stroke of the short screw.

(2) Double-push a support way? One end of the screw fixed support the other end. Fixed-end bearings at the same time to withstand axial and radial forces? Bearing bearing only bear radial force? And can make a small amount of axial float to avoid or reduce due to weight screw bending. At the same time screw thermal deformation can be freely extended to one end.
