About Us

From the Ocean Depths to Outer Space:
Engineering Motion at the Extremes

Under the immense pressure of the deep ocean and in the vacuum of space, machines still need to move. We make sure they can.

At the heart of this capability is tribology: the science of friction, wear and lubrication between interacting surfaces. Our expertise in controlling these interactions at the nanoscale is among the most advanced in the world, helping the most demanding machines ever built operate with precision and reliability.

From automobiles and advanced semiconductors to energy plants, deep-sea exploration vessels, satellites, and rockets, our technology is at work wherever motion has to be controlled.

The more extreme the environment, the more everything depends on getting the smallest details right. So, we pursue the extremes ourselves: extreme reliability, extreme safety, extreme efficiency.

Our progress drives advancement across both industry and society. As a member of the NOK Group, this is what we aim for: "Essential Core Manufacturing — The manufacture of pivotal products that shape society."
