NSK’s Business

The Industrial Machinery Business is involved in operations related to two product categories, namely industrial machinery bearings and precision machinery and parts.

Industrial machinery bearings meet a wide range of demands in all industries and come in a variety of types, ranging from miniature to extra-large size. On the other hand, represented by linear motion products, such as ball screws and linear guides as well as mechatronics products such as XY Tables and MEGATORQUE MOTORTM, precision machinery products play key roles in machine tools and semiconductor/LCD production equipment, which require precise positioning. Possessing thorough knowledge of industrial characteristics, operating environments, and national/regional differences, both businesses respond appropriately to a variety of needs.

Along with the trend of making it mandatory to equip vehicles with automatic emergency braking, there is an increasing shift toward electrification at the point of brake booster function. The ball screw is a promising type among several types of electric brake boosters. NSK, putting to use its global top share of ball screw technology, will continue to contribute to raising the level of safety in the brake field.

Stopping

Against a backdrop of the demand for greater environmental performance as a social issue, there is an ongoing shift toward the electrification of automotive components and a growing demand for bearings to perform in new positions. NSK is seeking growth by leveraging its strengths in the electrical components field where an ever-more sophisticated level of technology is required.

Running

Hub unit bearings are fundamental components that support the chassis while facilitating the rotation of the wheels. They are exposed to rainwater, mud, snow and other elements, and under such extreme environments realize excellent durability and smooth rotation.

Running

In efficiently conveying engine power to the tires, NSK products are critical to the transmissions that need to operate smoothly and with flexibility. We engage in Four Core Technologies plus One, namely tribology, materials, numerical simulation, mechatronics and manufacturing engineering, and offer products that enhance the efficiency of transmissions, making them increasingly compact and lightweight.

Turning

With the recent trend in advanced driving assistance and autonomous driving, electric power steering systems are increasingly important. In addition to the primary column-type EPS, the Company is making progress on the development of a rack-type EPS that puts to use NSK’s technological excellence. This is contributing to a broad product lineup and driving that is safe and comfortable.

Against the backdrop of stricter environmental regulations in countries throughout the world, the demand for improved automobile fuel efficiency and power saving performance has led to the expanded introduction of new energy vehicles (electric vehicles, hybrid vehicles, plug-in hybrid vehicles).

NSK provides advanced bearings and a newly developed pawl-type one-way clutch as the power transmission system for hybrid vehicles.

NSK Products: Supporting Automobile Running, Turning and Stopping

The Automotive Business is developing a wide range of important functional parts that support the three critical elements of automobiles̶namely running, turning and stopping̶in two businesses: automotive bearings and automotive components. The automotive bearings business provides various types of bearings used in automobiles, including hub unit bearings and needle bearings. The parts provided by the automotive components business include those for automatic transmission (AT) products, electric power steering (EPS) and ball screws for electric brakes.

Amid the accelerating innovation in automobile technologies, such as power source diversification and autonomous driving, we are advancing the development of new technologies and products, creating new value and making proposals.
