NSK BEARINGS

NSK was founded in 1916 and produced the first ball bearings made in Japan. Since then, the company has spearheaded the development of bearings in Japan. NSK now offers a full range of bearings and sells them worldwide. NSK bearings have contributed greatly to the growth of many industries and to the advancement of mechanical technology. Now, the company has the largest share of the bearings market in Japan and is one of the largest bearing suppliers in the world.
NSK has used its expertise in precision machining technology, refined through years of bearing manufacturing, to diversify into:
Since the beginning of the 1960s, following the establishment of its first overseas sales office in Ann Arbor, Michigan in the United States, NSK has continued to set up business locations overseas and has continuously strengthened its global presence.
In the 1970s, NSK established a manufacturing subsidiary outside the city of Sao Paolo in Brazil, followed by other new manufacturing subsidiaries in North America, in the United Kingdom and Asia. In the 1990s, NSK acquired UPI, the largest bearing manufacturer in the United Kingdom, known for its RHP brand. Expanding production and sales locations in all European markets resulted in a stronger market presence for NSK in Europe.
Starting in the mid-1990s, NSK rapidly expanded its operations into markets in Asia. Particularly in fast growing markets such as China, NSK is continuously strengthening its corporate structure to carry out research and development, sales and technical services locally.
NSK intends to step up its efforts on a company-wide basis to ensure that the business activities of the
entire company adhere strictly to applicable laws and regulations, and that they are conducted based on its social responsibilities as a corporation.
By further harnessing the potential of its global network, NSK strives to further enhance its R&D, Manufacturing, Sales and Management capabilities.
NSK is proud of its global network spanning the Americas, Europe, Asia and Japan. NSK operates 65 locations in Japan and 143 production sites and sales locations (excluding representative offices) as well as technical service locations in 29 countries around the world.
At all locations, our Business Division Headquarters, Functional Division Headquarters and Regional Headquarters work in close collaboration to meet the various needs of our global customers fast and accurately.
Product Features
1. New DLC coating provides improved skidding resistance under severe conditions
This new bearing comes with a roller-bearing-dedicated DLC coating that has ample delamination toughness for high-speed operations. Also, it achieves superior durability since its internal design has been optimized to suppress abnormal wear that can cause slipping even in usage conditions that have a pronounced tendency toward slippage and that have poor lubrication conditions as well as high speeds and light loads.
Furthermore, in revising the internal design of the bearings to reduce friction loss, the rated RPM level of this new bearing is double that of the current bearing, making it well suited for the high speeds of compressors.
2. Less bearing friction loss and less space required
In replacing the conventional combination angular contact ball bearing with this new single cylindrical roller bearing, the number of bearing needed is reduced while maintaining a high level of reliability and reducing the space required for the bearing.
