Since it first supplied ball bearings to the Japanese market in 1916, NSK has broadened its range and contributed to all different fields of industry. In particular, the company focused on and moved into the automotive products arena at an early stage. Placing an emphasis on performance and product quality, the company's business developed in tandem with the automobile industry.
Even now NSK is without rivals, supporting automobiles in their three crucial functions: “Running, Turning and Stopping”, thanks to its broad product range.
NSK automotive products are now a globally respected brand. Naturally the company supplies a wide variety of bearings, as well as automatic transmission parts and steering column, joints. Further, it also makes the electric power steering system (EPS), which is ready for the 21st century steer-by-wire technology.
NSK is always upgrading its Motion & Control technologies based on developments in the company's proprietary tribology (friction control technology) and mechatronics technologies that have been built up as a result of the company's rolling bearings business. In this way NSK is able to quickly respond to the needs of its customers around the world.
Various NSK products that are incorporated into automobiles have functionality and performance characteristics that control friction and reduce energy loss. We can say that they themselves are environmentally friendly products that contribute to reduced energy and resource requirements.
Through its new technology, NSK will continue to supply automotive products that are kind to the global environment and that add to vehicle safety and comfort.
NSK Experience & Technology
Since our founding in 1916, NSK has strived to be at the forefront of uncovering and responding to society's needs, offering new motion that no one has ever imagined. Today, NSK's Motion & Control™ can be found almost anywhere in the world. From our homes to high-tech factories, from massive construction machines to tiny medical instruments.
In the automotive industry, in line with our reputation as a top supplier to many of the biggest automakers, NSK solutions have already been adopted in leading electric vehicle models. The future of the automobile is looking bright as we continue to develop innovative products for EV and autonomous driving, as well as all core aspects of vehicle performance — driving, steering, and braking.
Products
Electric drive unit concept combines high-speed motor with traction drive speed reducer to reduce size and weight, and a magnetostrictive torque sensor and electric shift actuator to realize a high performance two-speed design. Benefits key areas of EV by extending vehicle range and enhancing driving performance, and contributes to ride comfort and drivetrain size and weight reduction.
NSK developed a high-efficiency rear wheel steering actuator with compact motor and low power consumption. The wheel angle is efficiently controlled by an actuator consisting of a ball screw and a newly developed locking clutch. The ball screw converts motor rotation into linear motion with minimal loss, and the locking clutch enables the wheel angle to be maintained with zero power consumption.
A low-friction ball screw improves brake response by enabling reliable high-speed operation and precise control. Integrated bearings and peripheral parts achieve compact size and low weight. This product is being adopted enable automated driving and to meet legal requirements for advanced emergency braking and collision damage mitigation systems.
Steer-by-Wire systems eliminate the physical connection between the steering wheel and the tires, enabling safety and comfort features previously difficult to achieve. NSK is currently developing force feedback actuators (FFA) and road wheel actuators (RWA), essential steer-by-wire sub-systems, as well as an electronic control paradigm that ensures safe operation even in case of failure.
