NTN : Exhibits at “AUTOMOTIVE ENGINEERING EXPOSITION 2023 YOKOHAMA”

NTN Corporation (hereafter, NTN) exhibits at “AUTOMOTIVE ENGINEERING EXPOSITION 2023 YOKOHAMA” to be held from May 24 to 26 in PACIFICO Yokohama, Kanagawa, Japan.

The needed specifications for automotive components are changing drastically as the shift to electrification of automobiles and the spread of EVs have been accelerating in the automotive market. Reflecting these market trends, NTN will exhibit at the event under the theme of “‘Nameraka’ × ‘Solution’ -Contribute to creation of the future in human, automobile, and society-” to propose NTN’s proprietary solutions for the future. We will exhibit products and services in the three areas of the booth: “products for e-Axle”, “products for drivetrain”, and “products for control system” such as electric hydraulic brake system, steer-by-wire etc.

In the “e-axle” Area, we will introduce products for e-Axle which is used as a driving source in EVs. e-Axle becomes more compact and its output power also becomes higher toward the extension of the cruising range and saving electricity. Thus bearings for e-Axle are required to achieve high speed rotational performance. Moreover, the bearings also need to address to electrical pitting. It is one of the damages of bearings occurred when electric current passes through the bearing and the metallographic structure melts, causing spalling (flaking) of raceway surface. In addition, the bearings are also required to deal with creep*¹. Creep becomes more likely to occur, as the motor housing becomes thinner. At the NTN booth, we will exhibit products that meet usage situations unique to e-Axle including High Speed Deep Groove Ball Bearings which achieves the world’s best level in high speed rotational performance with dmn value*² of 2.2 million, electrical pitting-resistant bearings using insulators, and “Creepless Bearing” which stops creep for the first time in the industry.

In the “Drivetrain” Area, we will exhibit hub bearings and driveshafts that pursue transmission efficiency. They are products with high function utilizing technologies that NTN has cultivated so far: “Low Friction Hub Bearing” that achieves low friction by reviewing greases and seals, High Efficiency Fixed Type CVJ “CFJ” that significantly reduces torque loss, Compact Lightweight Rear Driveshaft “R Series” that realizes lightweight with dedicated design for rear, and “GEN4 Hub Joint” that integrates hub bearing with driveshaft which NTN boasts high market share.

In the “Control system” Area, NTN will introduce various products that contribute to electrification of applications such as auxiliaries and brakes. In addition to ball screws used in electric braking systems, we will also exhibit high performance module products such as “Mechanical Clutch Unit (MCU) for Next-generation Steering” which contributes to safety in steering in automated driving, and “Combined Controller Module Electric Oil Pump” which adapts to a wide variety of operating conditions with lightweight and compact design.

NTN also exhibits at “AUTOMOTIVE ENGINEERING EXPOSITION ONLINE STAGE 1” held from May 17 to June 7 where we will introduce the same products exhibited at “AUTOMOTIVE ENGINEERING EXPOSITION 2023 YOKOHAMA” with photos, panels and others.

We look forward to seeing you at the event.
