The Future of Automotive Technology is Here​.

In the past, NSK’s automotive business was split into separate divisions for bearings and components. However, to address rapid innovations in automobile technology, in fiscal 2016 these were reorganized into two new divisions. Now, our powertrain division focuses on component products that support other mechanisms in the vehicle, while the steering and actuator division specializes in integrated system products that function as key mechanisms themselves. Our technology centers based in regions throughout the world work to develop products by leveraging our core technologies gained over a century in the business. Through component and system products, we tirelessly pursue the automotive technologies of the future.

NSK’s Automotive Business

Automotive Bearings

100 to 150 bearings are used in a single car, but with increasing environmental and safety needs, these bearings must be lighter and more efficient. NSK’s global production sites supply high quality products to automotive and component manufacturers across the world wherever bearings are used.

Steering Products

Nowadays, steering in automobiles is about much more than just turning the wheels. Electric power steering (EPS) systems are evolving to provide advanced driving maneuvers in self-driving vehicles.

Automatic Transmission (AT) Products

An automatic transmission (AT) enables smooth shifting and the effective relay of driving power. NSK’s AT products and needle roller bearings reduce frictional loss and allow automatic transmissions to have more gears.

High heat and large vibrations around the engine make an already harsh environment even more extreme. As such, bearings and engine components used here must be highly durable and reliable. With reliability as a top priority, NSK also responds to today’s needs for electrified, high-efficiency, lightweight, and compact products.
