Negative-Stiffness Vibration Isolator

Minus K Technology has introduced a compact, high-capacity, low-frequency negative-stiffness isolator designed to support heavy payloads while reducing low-frequency vibrations. The LC-4 isolator comes in several capacity ranges to match vibration-sensitive instruments for weight loads from 1 to 130 lbs. The LC-4 comes in two versions (low-frequency horizontal and ultra-low-frequency horizontal).  Both versions can deliver a vertical natural frequency of 0.5 Hz or less, which can be achieved over the entire load range. Horizontal natural frequency is load dependent. The low-frequency version has a 1.5-Hz natural frequency, while the ultra-low-frequency version can achieve 0.5 Hz or less near the nominal loads.
