NSK bearings have been leading the way in Japan since they first began producing bearings in 1916. As pioneers in the Japanese bearing industry, NSK has developed and provided a wide range of bearings, significantly contributing to the growth of the industry and the advancement of machinery. Today, NSK maintains the top position in the Japanese bearing market and ranks among the leaders globally. Moreover, leveraging the precision machining techniques honed in bearing production, NSK has been expanding its business across various fields, including automotive parts, precision machinery products, and electronic applications, for a long time.
NSK Bearings established its sales company in Ann Arbor, Michigan, in the early 1960s, marking the beginning of its efforts to build and operate an overseas network. In 1970, a production base was set up in the suburbs of São Paulo, Brazil, followed by the establishment of new production facilities in North America, the UK, and various Asian countries. Additionally, in 1990, NSK Bearings acquired UPI, a company that owned the European bearing manufacturer RHP. The NSK Bearings production and sales network spanning the entire European market is further solidifying NSK's dominant position in the European market.
Since the mid-1990s, NSK has accelerated its business expansion in China and the Asian region, especially for the rapidly growing Chinese market, establishing a comprehensive business system that encompasses self-research and development through to sales and technical services.
NSK Bearings will further promote the principle of compliance and legality across the entire group, uphold the corporate social responsibility, and continuously advance business activities. Through its global network, NSK Bearings is striving to enhance the mutual reinforcement of development, production, sales, and management capabilities, aiming for greater progress.
NSK's primary product is bearings, the foundation of all machinery; an indispensable product in modern society; renowned as the "grain of the mechanical industry"; it ensures the quality of all industrial products; NSK's mission is to operate and control; it delves into the root of machine operation/movement to ensure smooth rotation and operation; it is always present, constantly providing a rich and colorful life for humanity and contributing to the global energy-saving movement and resource conservation.
NSK has established sales networks in over 20 countries and regions globally and owns more than 50 factories, ranking among the world's top in the industry. To express gratitude to the vast majority of Chinese users, NSK is committed to exporting advanced production technology and management experience to the rapidly developing Chinese economy. We are gradually establishing and refining a trinity system centered on production, guided by technology, and supported by marketing information. NSK will accelerate the localization of this system, providing more direct and comprehensive services to a broad range of Chinese users and contributing to the modernization of China's industries.
NSK bearings, with pure materials and high product precision, offer a vast range of over hundreds of thousands of varieties. They are widely used in various environments and machinery, earning the nickname "the grain of the mechanical industry." With over 80 years of bearing production experience, NSK continues to improve existing products and develop new ones, maintaining a technological edge. With the widespread use of CNC machine tools and machining centers, industrial machinery has entered a new stage of mechatronics integration. This technological advancement is inseparable from NSK bearing products, represented by ball screws and linear guides. Their high-precision positioning technology excels in semiconductor manufacturing equipment and industrial robots, among other fields.
NSK ball bearings, typically consisting of rings, balls, and retainers, are categorized by the load direction they bear into radial and thrust bearings. Divided by the type of rolling elements, they are NSK ball bearings and NSK roller bearings. They can also be classified by their shape and specific user requirements.
NSK roller bearings feature, compared to sliding bearings, NSK roller bearings have the following advantages:
Low starting friction and minimal difference in sliding friction; internationally promoted standardization and specification, with good interchangeability, allowing for use across different brands. Referencing NSK bearing standards and SKF bearing standards, it is evident that imported rolling bearing standards are universally applicable.
Streamlined the structure surrounding the imported bearings for easier maintenance and inspection. Generally capable of withstanding both radial and axial loads. Easier to use under high and low temperature conditions.
To enhance rigidity, it can also be used even in negative clearance (preload state). Each structure of NSK rolling bearings features its own characteristics.
