The CFM Steel Spring Isolator type SSI is our latest innovation. CFM Schiller manufactures the type SSI in three different natural frequency ranges: 1.8 Hz, 2.5 Hz, and 5 Hz. Each isolator model can be offered with or without viscous damper; the installation height remains the same. The load capacity per isolator ranges from 22 kN to 384 kN.

Steel spring isolators type SSI are equipped with level elements, which minimize the amount of work needed for initial installation or readjustments. The level element can compensate differences in level of up to 50 mm (1.9 inches). Optionally, suitable compensation sheets for leveling purposes are supplied.
