SK Seiko's core technology is tribology, which is a discipline that studies the theory and application of friction, lubrication and wear between surfaces in relative motion, as well as the relationship between the three. With tribology as the core, we use analytical technology to reduce energy loss, material technology to ensure product life, lubrication technology to reduce energy consumption, and evaluation technology to accurately verify products, thereby providing a continuous source of power for the development of an intelligent society.
