Since NSK began producing bearings in Japan in 1916 as a pioneer in the industry, it has made significant contributions to the development of the industry and the advancement of machinery by developing and providing a variety of bearings. Today, NSK is the leader in the bearing field in Japan and also ranks among the top globally. Furthermore, leveraging the precise machining technology honed in bearing production, NSK has been expanding into diverse fields, such as automotive parts, precision mechanical products, and electronic applications, from an early stage, propelling its multifaceted business growth.
NSK established its sales company in Ann Arbor, Michigan, in the early 1960s, marking the beginning of its journey to establish and operate overseas business locations. In 1970, a production base was set up in the suburbs of São Paulo, Brazil, followed by new production sites in North America, the UK, and various Asian countries. Additionally, in 1990, NSK acquired UPI, a company owning the European bearing manufacturer RHP. The NSK bearing 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, particularly 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 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 strives 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; famously known as the "grain of the mechanical industry"; it ensures the quality of all industrial products; NSK's mission is to operate and control; delving into the root of machine operation/motion 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, with 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 development. Gradually, NSK is establishing and refining 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, providing Chinese users with more direct and comprehensive services and contributing to China's industrial modernization.
NSK bearings, with pure materials and high product precision, offer a variety of tens of thousands, widely used in different environments and machinery, known as 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 technical edge. With the widespread use of CNC machines and machining centers, industrial machinery has entered a new stage of electromechanical integration. This technological advancement is inseparable from NSK bearing products, such as ball screws and linear guides, which excel in high-precision positioning technology, particularly in semiconductor manufacturing equipment and industrial robots.
NSK roller bearings are generally composed of races, 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 special features:
Low starting friction and small difference in sliding friction; internationally promotes standardization and specification, with good interchangeability, allowing for use across different brands. Referring to NSK bearing standards and SKF bearing standards shows that imported roller bearing standards 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 (preload state). Each structure of NSK roller bearings has its own characteristics.
