**Press Release Information**
Title: Exhibiting at "Automotive Engineering Exposition 2026 YOKOHAMA"
NSK Ltd. (Headquarters: Shinagawa-ku, Tokyo; Representative Director and President & CEO: Akihito Ichii; hereinafter, NSK) will exhibit at "Automotive Engineering Exposition 2026 YOKOHAMA," hosted by the Society of Automotive Engineers of Japan, to be held at Pacifico Yokohama from May 27 (Wednesday) to May 28 (Friday), 2026.
**Overview of the Event**
This event is one of Japan's largest annual automotive technology exhibitions, featuring car manufacturers and parts suppliers. Key visitors primarily include engineers and researchers in the automotive and mobility sectors, along with many students and research institution personnel. The previous event (2025) saw 617 participating companies and approximately 80,000 visitors.
**NSK Exhibition Concept: "Mobilizing Tomorrow Today"**
NSK will exhibit products responding to the electrification and sophistication of automotive functions—"Driving," "Turning," "Stopping," and "Comfort"—as well as humanoid robot-related products aimed at automating manufacturing sites to address labor shortages.
**Main Exhibits**
* **Electric Corner Module Concept**
This concept model integrates electric suspension, rear-wheel steering actuators, and electric mechanical brakes, which are key functions for vehicle intelligence, to achieve flexible vehicle layouts. NSK aims to promote innovation in future mobility by providing ball screws and locking clutches applicable to these electric actuators, as well as low-friction hub unit bearings (see figure below).
NSK products contributing to the functional improvement of electric vehicles (Electric Corner Module Concept)
* **Driving: Ultra-narrow Hub Unit Bearing [World First Exhibition / Reference Exhibition]**
As mobility forms diversify, there is a demand for high-dimensional coexistence of three performances—driving, steering, and braking—within limited vehicle space. This bearing significantly reduces bearing width by overlapping two rows of balls in the axial direction (Figure 1).
This secures mounting space for in-wheel motors with reduction gears (Figure 2), contributing to larger and higher-output motors. Additionally, the drive shaft can be designed to be longer than conventional designs (Figure 3), increasing the maximum steering angle of the tires and contributing to improved maneuverability of the vehicle.
* **Driving: Sprag Selectable One-Way Clutch [World First Exhibition / Reference Exhibition]**
This is a mode-switching clutch that adds a bidirectional free mode to a highly reliable sprag one-way clutch, contributing to higher system efficiency while ensuring high reliability as an ICE direct clutch for PHEV/HEV.

* **Driving: Anti-Electrolytic Corrosion Solution for eAxle [Conductive Bypass Plate: Reference Exhibition, Resin Molded Bearing: Marketed]**
In eAxles, countermeasures against electrolytic corrosion, where bearings are damaged/degraded by current due to higher motor output/voltage and increased carrier frequency, have become a challenge. NSK provides optimal anti-electrolytic corrosion solutions combining both conductive and insulating approaches depending on the electrolytic corrosion situation, contributing to improved reliability of eAxles.
* **Turning: Steering Reaction Force Device with Ret retractable Electric Tilt-Telescopic Column [First Exhibition at Automotive Engineering Exposition, Reference Exhibition]**
With the advancement of autonomous driving, effective utilization of interior space and new interfaces connecting people and cars are demanded. By integrating a handle retraction function into the steering reaction force device for steer-by-wire, the steering wheel can be retracted into the dashboard during autonomous driving, expanding the space in front of the driver. Furthermore, high-speed operation enables smooth retraction and return without causing discomfort to the driver.
* **Turning: Locking Clutch for Rear-Wheel Steering Actuator [Reference Exhibition]**
This newly developed product achieves both high power transmission efficiency and reliable locking function without using electricity, contributing to the efficiency and miniaturization of rear-wheel steering actuators. By incorporating this product with a ball screw into a rear-wheel steering actuator, it maintains a self-locking function with zero power consumption while improving the transmission efficiency of steering force from the motor to the tires (see figure below).

* **Stopping: Ball Screw for Electric Hydraulic Brake [Marketed]**
This product is a highly reliable ball screw that adopts newly developed materials. Leveraging expertise in bearing production, it achieves integration of the circulation part and nut, as well as functional integration with support bearings and peripheral components, contributing to the miniaturization and weight reduction of brake systems.
Furthermore, with changes in vehicle needs due to autonomous driving and electrification, electric mechanical brakes (EM), which combine high responsiveness, controllability, and layout freedom as next-generation brake systems, are attracting attention.
