The forging of a Japanese blade in ancient times took many weeks, and was considered a sacred art. Blades were often forged with different profiles, different blade thicknesses, and varying amounts of grind.

The steel used is known as tamahagane, or “jewel steel”.

Nachi Fujikoshi is an industry leader in Machining, Robots, Industrial Components and Materials; the perfect combination between industries, knowledge and tradition to produce the spherical roller bearing with “The Largest Load Rating in the World”.

The mission of Nachi Fujikoshi

The company’s mission is to contribute to the progress of the world of product manufacturing.

Overview of Nachi products

There are 4 major product groups: Machining products, Robots, Components and Materials. All the product divisions are connected and synchronized with each other in order to produce the best and highest quality products.

Some of Nachi’s Machining products are Cutting Tools, Forming Tools, Broaches, Machine Tools, Precision Machinery and Machining Systems. The Components division is responsible for Bearings, Hydraulic Equipment and Automotive Hydraulics. The Components division is working very closely with the Materials division which is in charge of Special Steels, Coatings and Industrial Furnaces.

Sales by turnover, product groups and markets

Company’s turnover is $1.9 billion. The bearings product group is worth for 37% and the automotive market for 53% of all Nachi sales.

Nachi Fujikoshi production start and evolution history

Nachi Fujikoshi was founded in Toyama City, Japan by the founder, Mr. Kohki Imura in 1928. The company was founded with the aim of becoming a domestic manufacturer of cutting tools and machine tools in the trend towards industrial modernization. This aim was fulfilled very fast and the company’s business activities expanded on high speed during the first 20 years after establishment.

The production of bearings started in 1939 with the set up and apply grinding and heat treatment technologies in the product lines. Nachi produced firstly ball bearings and spherical roller bearings with high-quality materials.

In the 1950’s the bearing production line was expanded with special-purpose bearings and railway bearings. After the development of high-quality bearing by the special Steel division in early 1960’s, Nachi started the production line for Jet engine bearings. This process was followed by the development of hot press forming technology for inner/outer rings and resulted with the production of Triple-race bearings and bearing for printing presses.

In the 1980’s a new program was started with the Steel Section for the production of long-life bearings. During this program the automotive air condition bearings and roller bearings for synchronized joints came into production. The production of 4-point contact ball bearings started in 1993.

After 1973, the production of bearings was internationalized by establishing factories in Brazil, USA, Thailand, China, Taiwan and India for the production of sealed support bearings, Quest ball bearings series and EX-V rollers bearing series.

The difference between Nachi and other producers

Current position that Nachi has on the world markets is due to the great importance it grants to its customers’ demands. All the company’s products are produced according to the international standards and with high precision and quality. Nachi’s professional teams from the production to the sales are enabling the company to be one step ahead in this industry.

Nachi has a vertical integration and doesn’t depend on external vendors for assuring the quality of work. All the products are manufactured in own plants, with own specially engineered machine tools by using own tooling. They even make their own steel and heat treat it in furnaces of own production.

This means that Nachi control every aspect of the manufacturing process. Quality builds on quality, every step of the way. In this way, they ensure the quality by maintaining rigorous standards which are continuously monitored and improved. Accountability for quality begins and ends with Nachi. The customers can trust Nachi products because the company’s reputation is everywhere at the production line.

Spherical Roller Bearings

Nachi spherical roller bearings are produced to obtain resistance under heavy loads. They were designed with a uniform internal geometry between the raceway and the rollers. The most important is that the Steel Section has developed long life bearing steel which is used for the production of the spherical roller bearings.

Thanks to the knowhow on bearing steel, there is currently a more sensitive and better controlled heat treatment technology for the production of bearings which can operate safely under hard conditions. Standard bearings lose their size precision over 120°C and the format of the steel starts changing on micro levels. These micro changes cause loss of hardness in the bearings and the steel suffer from loss of working life and it loses the capacity to carry loads. The heat treatment technology used by Nachi on bearings enables the bearing steel to maintain the micro structure and prevents the loss of hardness even under the working conditions at 200°C. This special treatment stops premature break-downs by preventing high temperature changes. Operation under condition of 200°C is a standard for Nachi Spherical Roller Bearings.

Besides the internal geometry, steel quality and the high-tech heat treatment process, the size of the rollers used in the spherical roller bearings and the design of the cage structure are also playing an important role by achieving the “highest load rating” available on the market. This result is an achievement of the synergy between Cutting Tools, Design and Production departments that are involved in the production of the bearings components.

The success of Nachi Fujikoshi

The success lies in the company’s philosophy, which was defined by its foundr, Mr. Kohki Imura. It pertains to the 5 aspects of the Corporate Philosophy as a fundament during the daily work.

Creativity – Business withers without creation.

Today’s dream brings a better tomorrow. Creation causes some discord. Improvement is assured by conquering such discord.

Aggressiveness – Tackle your job aggressively.

Give priority to difficult assignments and never give up when the job is half done.

Globalism – The globe is your market.

Win the trust of the people of the world. Supply quality products at reasonable cost. Nurture the competitiveness of your products.

Appreciative minds– Always be appreciative of what people around you do for you.

Thank your parents for having given birth to you. Thank elders for their guidance. Serve the community in order to reciprocate its hospitality towards you.

Human assets – To make the company prosper, is to find and work with the right person for the right job.

Quality people are difficult to come by. Be objective. Be health conscious. Be wise. Stick to your words.
