POINT1 NTN's major product lines will not decrease, even with EVs.

The number of hub bearings and driveshafts used will not decease

With the shift to EVs, vehicle power units will change from engines to motors, and conventional engines and transmissions will not be used. Therefore, the number of bearing used in them will decrease. Yet even with EVs, hub bearings that make the tires turn smoothly, and driveshafts that transmit the motor's rotation to the tires will still be required. As such there will be no change in the number of hub bearings and driveshafts, which are NTN's major product lines.

Hub bearings and driveshafts account for a major ratio of sales

There are a large number of bearings used in the engine and transmission of each single vehicle, however the majority of them are small in size. In contrast, there are fewer hub bearings and driveshafts used, however they are larger in size and they have a higher added value.
Hub bearings and driveshafts account for 80% of NTN sales in the automotive market.

Hub bearings

It is important that the four wheels of a car turn efficiently for smooth driving.
Hub bearings help the tires turn, and play an important role as they support the weight of the car while the wheels turn. NTN's hub bearings are unitized and have less parts, which means they are more lightweight and compact, to contribute to lower fuel consumption as well as higher safety.

Driveshafts

Driveshafts are parts that transmit drive power from the engine to the tires, and NTN was the first to commercialize them in Japan.
Since then, NTN has continued to lead the industry with its high level of technical expertise, developing and supplying high-performance, lightweight and compact driveshafts with a long operating life for automobiles, as well as for various other industries such as steel manufacturing machinery, food machinery and medical devices.

POINT2 NTN has a large range of products for next-generation vehicle including EVs.

Next-generation vehicles are becoming more electrified, and acceleration, brakes and other control and operating mechanisms are shifting from mechanical transfer systems to electrical transfer systems (by-wire).
With these changes, NTN announced that it will focus on expanding into new markets related to electrification in its medium-term management plan "NTN 100," NTN will continue to identify changes in the automotive market and harness its existing strengths with the aim of high growth.

Changes in the market for automotive products

As society seeks more efficient use of resources and actions that contribute to environmental conservation, the demand for vehicles will decrease into the future and the number of EV (electric vehicles) being used is expected to increase.
