Since NSK began producing bearings in Japan in 1916, as the pioneer in Japanese bearing technology, we have developed and provided a wide range of bearings, making significant contributions to the industry's growth and mechanical advancements. Today, NSK is the leading bearing manufacturer in Japan and also ranks among the top globally. Additionally, leveraging the precision machining technology honed in bearing production, NSK has been expanding its business in various fields, including automotive parts, precision machinery products, and electronic applications, from an early stage.

NSK bearings established its sales company in Ann Arbor, Michigan, in the early 1960s, marking the beginning of its journey to build and operate overseas business outlets. 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 Asia-Pacific region, particularly for the rapidly growing Chinese market, establishing a comprehensive business system that encompasses independent research and development, sales, and technical services.

NSK Bearings will further implement the principle of adherence to laws and regulations throughout the entire group, upholding the corporate social responsibility, and continuously promote its business activities. Through its global network, NSK Bearings endeavors to strengthen the interconnection between 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; renowned as the "grain of the mechanical industry"; it guarantees the quality of all industrial products; NSK's mission is focused on operation and control; delving into the root of machine operation/motion to ensure smooth rotation and operation; it is ever-present, constantly enriching human life and contributing to global energy conservation efforts and resource protection.

NSK has established sales networks in over 20 countries and regions worldwide, with more than 50 factories, ranking among the world's 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 the rapidly developing Chinese economy. We are gradually establishing and refining a trinity business system centered around production, guided by technology, and supported by marketing information. NSK will accelerate the localization of this system, providing Chinese users with more direct and comprehensive services and contributing to the modernization of China's industries.

NSK Bearings, with pure materials and high product precision, offer a vast range of over 300,000 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 continuously improves existing products and develops new ones, maintaining a technological edge. As CNC machine tools and machining centers become increasingly prevalent, the industry has entered a new stage of electromechanical 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 roller bearings are typically composed of shells, rolling elements, and retainers. They can be categorized into radial bearings and thrust bearings based on the load-bearing direction. According to the type of rolling elements, they are classified as NSK ball bearings and NSK roller bearings. They can also be further categorized by shape and for specific user requirements.

NSK Roller Bearings Features, compared to sliding bearings, NSK roller bearings have the following special features:

Low starting friction and small difference in sliding friction. Internationally, it has promoted standardization and specification, with good interchangeability, allowing for use across different brands. Referring to NSK bearing standards and SKF bearing standards, it is evident that the standards for imported rolling bearings are universal.

Streamlined the structure around 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 be used even in negative clearance (pre-loaded state). Each structure of NSK roller bearings has its own characteristics.
