NSK bearings, since their inception in 1916 as the pioneers in Japan's bearing production, have made significant contributions to the development of the industry and the advancement of machinery by developing and providing a wide range of bearings. Today, NSK holds the top position in the Japanese bearing market and is also a leader globally. Moreover, leveraging the precision machining techniques honed in bearing production, NSK has been expanding its business in various fields, including automotive parts, precision mechanical products, and electronic applications, since a long time ago.
NSK bearings established its sales company in Ann Arbor, Michigan, in the early 1960s, marking the beginning of its efforts to build and operate a global network of overseas business locations. In 1970, a production base was set up in the suburbs of São Paulo, Brazil, followed by 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. With production bases and sales outlets spanning the entire European market, NSK bearings are further solidifying their dominant position in the European market.
Since the mid-1990s, NSK has accelerated its business expansion in China and the Asian region, particularly for the rapidly growing Chinese market, establishing a comprehensive business system that includes independent research and development, sales, and technical services.
NSK Bearings will further implement the principle of compliance and lawfulness across the entire group, upholding the company's social responsibility, and continuously advance its business activities. Through its global network, NSK Bearings is committed to enhancing the mutual reinforcement of development, production, sales, and management capabilities, striving for greater progress.
NSK's primary product is bearings, the foundation of all machinery; an indispensable product in modern society; famously known as the "grain of the mechanical industry"; it ensures the quality of all industrial products; NSK's philosophy revolves around operation and control; delving into the root of machine operation and friction phenomena to ensure smooth rotation and operation; it is ever-present, constantly enriching human life and contributing to global energy-saving initiatives and resource conservation.
NSK has established sales networks in over 20 countries and regions worldwide and owns more than 50 factories, ranking among the top in the industry. To express gratitude to the vast number of Chinese users, NSK is committed to exporting advanced production technology and management experience to China, which is experiencing continuous and rapid economic growth. We are gradually establishing and perfecting a three-in-one business system centered on production, guided by technology, and supported by marketing information. NSK will accelerate the localization of this system to provide more direct and comprehensive services to a wide range of Chinese users and contribute to the modernization of China's industries.
NSK bearings, with pure materials and high product precision, offer a variety of tens of thousands of types. They are widely used in different environments and machinery, earning the nickname "the grain of the mechanical industry." With over 80 years of bearing production experience, NSK continuously improves existing products and develops new ones, maintaining a technological edge. As CNC machine tools and machining centers become more prevalent, industrial machinery has entered a new stage of mechatronics integration. This technological advancement is inseparable from NSK's bearing products, represented by ball screws and linear guides. Their high-precision positioning technology excels in fields such as semiconductor manufacturing equipment and industrial robots.
NSK ball bearings, generally composed of rings, balls, and retainers. They can be categorized into radial bearings and thrust bearings based on the load direction they bear. According to the type of rolling elements, they are divided into NSK ball bearings and NSK roller bearings. Additionally, they can also be classified by shape and specific user requirements.
NSK roller bearings feature, compared to sliding bearings, NSK roller bearings have the following special advantages:
Low starting friction and minimal difference in sliding friction. Internationally, it promotes standardization and specification, with good interchangeability, allowing for use across different brands. Referencing NSK bearing standards and SKF bearing standards shows that the standards for imported rolling bearings are universal.
Streamlined the construction around the imported bearing 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 be used even in negative clearance (preload state). Each structure of NSK roller bearings features its own characteristics.
