Four Core Technologies

100 Years of Technology: Setting the Future in Motion
For nearly a century since its founding in 1916, NSK has focused efforts on R&D, developing new technologies and raising product quality. Having grown into a leading company in the fields of bearings, automotive products, and precision machinery and components, NSK's technological capabilities are based on four core technologies: tribology, materials, simulation, and mechatronics.

Tribology

Improving Performance by Optimizing Friction
Tribology is the study of friction and wear of contact surfaces in relative motion, such as rotating parts that endure enormous forces with a thin oil film. Severe operating conditions are optimized through lubrication and surface treatments developed by NSK, resulting in superior performance for applications requiring low friction, high-speed rotation, quiet operation, or enhanced durability.

Materials

Superior Performance for Any Application
Materials research and development affects nearly every aspect of product performance. Through careful selection of material composition, heat treatment, and use of ceramic materials, NSK enables optimization of application performance. This may be through improvements in function, endurance, reliability, or even through improvements in cost effectiveness or production efficiency.

Numerical Simulation

Turning Blind Risk Into Trusted Reliability
In the past, accuracy and reliability in product development were achieved with experience-based design and longer testing periods. NSK's simulation technology allows for virtual validation to accelerate design and production. Extreme conditions or innovative designs that defy previous expectations can also be evaluated and analyzed.

Mechatronics

Technology Supporting People for a Safe and Comfortable Future
Mechatronics refers to the combination of mechanics and control technologies. NSK has cultivated knowledge of mechanics through years of product development and production. This knowledge is used in conjunction with motors, sensors, and circuits to develop mechatronic systems that add new functions, improve reliability, and increase performance in various industries while also improving convenience and safety in our daily lives.
