The introduction of NSK bearing
NSK's main product is the bearing, which is the foundation of all machines; it is an indispensable product in modern society and it ensures the quality of all industrial products. NSK's purpose is to operate and control; the operation/friction phenomenon of the machine is investigated to ensure the smooth rotation ; it is always present and provides human with a variety of Living and will contribute to the global energy conservation movement and resource protection.
NSK has established a sales network in over 20 countries and regions around the world and has more than 50 factories, ranking the top in the world. To thank Chinese users for their trust, NSK is committed to exporting advanced production technology and management experience to China with sustained and rapid economic development, and gradually establish and improve the three in one business system with production as the core, technology as the guide, and marketing information as the auxiliary. NSK will speed up the localization process of this system to provide more direct and complete services for Chinese users. Excellent service makes a due contribution to China's industrial modernization.
NSK bearing, with pure material, high product precision, and hundreds of thousands of varieties, is widely used in different environments and machines. NSK, which has more than 80 years of bearing production experience, continues to improve the existing products, develop and develop new products, and always keeps the leading edge in technology. With the full application of CNC machine tools and machining centers, industrial machinery has entered a new stage of the mechatronics Paragraph. This technical progress is inseparable from NSK bearing products represented by ball screw and linear guide rail. Its high-precision positioning technology plays a vital role in semiconductor manufacturing devices and industrial robots.
The classification of NSK bearing
NSK rolling bearing is generally composed of the ferrule, rolling element, and cage. According to the load-bearing direction, it can be divided into radial bearing and thrust bearing. According to the type of rolling element, it is divided into NSK ball bearing and NSK roller bearing. It can also be classified according to its shape and specific users.
Compared with plain bearing, NSK rolling bearing has the following advantages:
1. The starting friction is small, and the difference between sliding friction and control is low. Standardization and normalization are promoted internationally, with good interchangeability, which can be used interchangeably among different brands. Referring to the NSK bearing standard and SKF Bearing standard, it can be seen that the standard of imported rolling bearing is universal.
2. The structure around the inlet bearing is simplified, which is convenient for maintenance and inspection. Generally, it can bear radial load and axial load at the same time. It is easy to use under high and low-temperature conditions. To improve the rigidity, it can be used even in negative clearance (preload state).
In NSK ball bearing, the function of deep groove ball bearing can not be ignored, especially 6302 series bearing: outer diameter 42mm, thickness 13mm, Cr rated dynamic load (n) 11400, cor rated static pressure (n) 5450, Cr rated active weight (kg) 1170, cor rated static capacity (kg) 555.
Also, NSK linear bearing plays an important role. Low-cost production, used for unlimited travel and cylindrical shaft, widely used in precision machine tools, textile machinery, food packaging machinery, printing machinery, and other industrial machinery, is sliding parts. However, please note:
(1) After disassembling each part of the linear bearing series, foreign matters may enter, or the assembly accuracy of each piece may be adversely affected；
(2) The linear bushing may be damaged by falling or knocking. When the product is impacted, the function may be damaged even if the appearance is not damaged.
