Performance/Features

1. Suitable for building materials

It is suitable for anti-vibration applications such as studios, anechoic chambers, and pipe supports.

2. Widely used for large loads

With a maximum supporting load of 24,500 N per piece, it can be used for large loads, expanding its range of applications.

3. Suitable for preventing high frequency vibration

Due to its large spring constant, it can be used in large machines and is suitable for preventing the transmission of high-frequency vibrations.

3. Wider applicability depending on mounting direction

・It can be used in both shearing and tilting directions, and can also be used effectively for low-frequency vibration.
・When used in two stages, the natural frequency can be set as low as 1/√2 of the first stage.
・By using the through-hole type, you can consider the mounting method, such as post-installation in places where there is no space.

4. No seismic measures required

The through-hole type can be easily attached to bolts through the central hole and can be used as an anti-seismic measure.
