Since NSK began producing bearings in Japan in 1916 as a pioneer in the field, the company has developed and supplied a wide range of bearings, making significant contributions to the development of the industry and the advancement of machinery. Today, NSK is the leading player in the Japanese bearing market and also ranks among the top globally. Moreover, leveraging the precision machining techniques honed in bearing production, NSK has early on expanded into diverse areas such as automotive components, precision mechanical products, and electronic applications, driving its multifaceted business expansion.
NSK established its sales company in Ann Arbor, Michigan, USA, in the early 1960s, marking the beginning of its journey 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 bases in North America, the UK, and various Asian countries. Additionally, in 1990, NSK acquired UPI, a company that owned the European bearing manufacturer RHP. The NSK bearing production and sales network spanning across 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 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 adhering to laws and regulations across the entire group, upholding the company's social responsibility, and continuously advance its business activities. Through its global network, NSK Bearings strives to enhance the interplay between development, production, sales, and management capabilities, aiming for greater progress.
NSK's primary product is bearings, the foundation of all machines; an indispensable product in modern society; famously known as "the grain of the mechanical industry"; it guarantees the quality of all industrial products; NSK's aim is in operation and control; it delves into the root of machine operation and friction to ensure smooth rotation and operation; it is ever-present, constantly enriching human life and contributing to global energy conservation and resource protection initiatives.
NSK has established sales networks in over 20 countries and regions worldwide and owns 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 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 material and high product accuracy, offer a variety of over hundreds of thousands, widely used in diverse environments and machinery. They are often referred to as "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. With the widespread application of CNC machine tools and machining centers, industrial machinery has entered a new stage of mechatronics integration. This technological advancement would not be possible without NSK's bearing products, represented by ball screws and linear guides. Their high-precision positioning technology is particularly prominent in semiconductor manufacturing equipment and industrial robots.
NSK roller bearings are typically composed of rings, rolling elements, and retainers. They can be categorized as either radial bearings or thrust bearings based on the load direction they support. According to the type of rolling elements, they are classified into NSK ball bearings and NSK roller bearings. They can also be further categorized by their 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 has promoted 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 universally applicable.
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 (pre-load state). Each structure of NSK roller bearings features its own characteristics.
