Anti-vibration rubber
It has a simple structure and is easy to install.
Since it is compact and has a relatively large spring constant, it can support a large load.
Depending on the mounting direction, it can be used in the compression direction, shear direction, and tilt direction, and has a wide range of applications.
Has excellent weather resistance and mild oil resistance.
