Automotive Market Main Products

Hub bearings and driveshafts

Hub bearings with the world’s No.1 market share and driveshafts with the world’s No.2 market share account for approximately 80% of NTN’s sales in the automotive business. These products continue to be applied in EVs (Electric Vehicles) as well.

Hub bearingsWorld's No. 1 share

It is important that the four wheels of a car turn efficiently for smooth driving. Hub bearings help the wheels turn, and play an important role as they support the weight of the car at the same time. NTN's hub bearings are unitized and have less parts, which means they are more lightweight and compact. This helps to reduce fuel consumption as well as improve safety.

DriveshaftsWorld's No. 2 share

Driveshafts are parts that transmit drive power from engines and motors 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 to various other industries such as steel manufacturing machinery, and food machinery.

Business Topics

Driven by electrification and shift to EVs

In the automotive market, electrification of automobiles and shift to electric vehicles (EVs) are accelerating. Accompanied with the shifts, the requirements for each product are also changing. NTN regards the change as business opportunities where we can demonstrate our technologies. Through developing and providing high value added products that meet EV’s specific needs, we are expanding the business.

Strengthen core technologies and products

In order to meet EV's needs, NTN will deepen our accumulated technologies for core products of hub bearings and driveshafts where NTN has a high global market share, and other bearings. To increase all-electric range of EVs, hub bearings are required to reduce friction and weight to lower electricity consumption. Driveshafts are required to realize high efficiency to transmit the motor torque to the wheels without compromising the torque, and low vibration/quietness characteristics to improve ride comfort as well as lightweight. Additionally, in order for the motors to produce sufficient torque, bearings adaptable to high speed rotation are needed. NTN has already been developing and providing products that meet these needs, and will continue to develop products that anticipate changes in needs.

Expand into new areas

NTN is accelerating the development of highly functional module products that leverage the technologies cultivated through the development of core products to date. Electric Motor and Actuator, which combines bearing and ball screw technologies with motor design technologies and electronic control technologies, contributes to the electrification of various components such as oil pumps and brakes as linear actuator and rotary actuator that can be electronically controlled. We are also developing products that contribute to fuel efficiency and future automated driving by combining hub bearings with motors, generators, and steering assist functions.

Contributing to growth of renewable energy market

NTN began manufacturing of bearings for wind turbines in 1998, and has been supplying bearings for main shafts, gearboxes, generators, and yaw gearboxes. Main shafts transmit rotation generated by blades. Gearboxes increase the rotation speed and transmit it to the generators. Generators convert the rotational energy from the gearboxes to electricity. Yaw gearboxes change the direction of the turbine in accordance with the direction of the wind.
Furthermore, we began selling Green Energy Products that generate electricity from renewable energy such as wind and solar in 2016, utilizing our technologies cultivated from development of bearings for wind turbines. Transportable Independent Power Supply “N3 N-CUBE” and Stationary Power Supply “NTN Green Power Station” can be customized to suit usage conditions. They are installed in many place in Japan.
NTN contributes to the growth of renewable energy market through the provision of bearings for wind turbines and Green Energy Products.

Provide one-stop solution from supplying bearings to abnormality detection and maintenance for wind turbines

While renewable energy is getting attention to realize carbon neutrality, there are great expectations for offshore wind turbines in particular. NTN plays a key role in supply chain as one of the few manufacturers capable of producing bearings for main shafts used in offshore wind turbines which are larger in size.
In addition to providing bearings, we have been supplying monitoring service and diagnostic service for the bearings by using our condition monitoring systems (CMS). Sensors are attached to the drive train (main shafts, gearboxes, and generators) of the wind turbines to obtain data such as vibration. By monitoring and analyzing the data, it can detect signs of damage in bearings and gears.
Through collaboration with the business partner which specializes in maintenance business for wind turbines, we can also provide maintenance service quickly when abnormalities are detected by CMS. By utilizing CMS data, we can conduct accurate and efficient maintenance, minimizing downtime of facility.
As a supplier which can provide one-stop solution to operate wind turbines from supplying bearings to abnormality detection with CMS, as well as supplying maintenance, NTN contributes to stable operation of wind turbines and expansion of the market.

Contribute to automation, labor saving, and improvement in productivity at manufacturing sites

In the robots market, where its demand is rising against the backdrop of a decrease working population, NTN is contributing to automating manufacturing sites, saving labor, and improving productivity through the provision of robot-related products such as Wrist Joint Module “i-WRIST™” and “Multi Track Magnetic Ring.”
“i-WRIST™” features free movement like human wrists with our original driving mechanism utilizing technologies of driveshafts where we have the world's No.2 market share. It can provide high precision positioning at high speed. By attaching end effects such as cameras and cleaning nozzles to the tip of “i-WRIST™,” it can replace the various processes that were carried out by human.
“Multi Track Magnetic Ring” is formed of a double-row magnetic track with a highly accurate magnetization technology. It adheres a highly durable rubber material kneaded with a magnetic material to a ring-shaped core metal.
Combined with a dedicated magnetic sensor, it enables angle detection with high resolution and contributes to precise movement control by applying it to joints of robots.
