Since NSK began producing bearings in Japan in 1916, as a pioneer in the field, we have developed and provided a variety of bearings, making significant contributions to the industry's development and mechanical advancements. Today, NSK is the leading bearing manufacturer in Japan and ranks among the top globally. Moreover, leveraging the precision machining techniques honed in bearing production, NSK has long been expanding its business through entries into the automotive parts, precision machinery products, and electronic application product markets.
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 Asian region, particularly for the rapidly growing Chinese market, establishing a comprehensive business system that encompasses self-research and development, sales, and technical services.
NSK Bearings will further promote the principle of compliance with laws and regulations across the entire group, uphold the company's social responsibility, and continuously advance its business activities. Through its global network, NSK Bearings is striving to enhance the interplay 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 philosophy is focused on 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 efforts.
NSK has established sales networks in over 20 countries and regions worldwide and operates more than 50 factories, ranking among the top globally 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 development. We aim to gradually establish and refine a three-in-one business system centered around production, guided by technology, and supported by marketing information. NSK will accelerate the localization of this system, thereby providing Chinese users with more direct and comprehensive services, and contributing to the modernization of China's industries as we should.
NSK Bearings, with pure materials and high product precision, offer tens of thousands of varieties. They are widely used in various environments and machinery, renowned as the "grain of the machinery 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 use of CNC machine tools and machining centers, the industry has entered a new stage of mechanical and electrical integration. This technological advancement is inseparable from NSK bearing products, such as 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 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 divided into NSK ball bearings and NSK roller bearings. They can also be classified based on their shape and specific user requirements.
NSK roller bearings features, compared to sliding bearings, NSK roller bearings have the following 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, it is evident that imported rolling bearings adhere to universal standards.
Streamlined the structure around the imported bearings for easier maintenance and inspection. Generally capable of withstanding both radial and axial loads. More suitable for use under high and low-temperature conditions.
To enhance rigidity, it can be used even in negative clearance (preload state). Each NSK roller bearing structure has its own characteristics.
