Various models of Minus K negative stiffness vibration isolators

Negative Stiffness Passive Isolation

Minus K® have developed a revolutionary new method for passive vibration isolation. Using a system of springs and negative stiffness mechanisms, Minus K®’s technology provide isolation performance up 100 times better than air systems. Isolation is provided in 6 degrees of freedom, and with resonant frequencies as low as 0.5 Hz.

With no air, electricity or maintenance required, Minus K® isolators are easy to install and use. The negative stiffness technology has been adapted for a wide range of form factors, including ultra-thin and ultra-compact sizes.
