This has a positive influence on the life of a machine and helps to abate noise. Using the details on the maximum static load F, the maximum permissible compression and the resulting stiffness, the achievable degree of insula- tion can be determined with the help of the method shown on page 1491. The details relating to the load bearing capacity are non-binding recom- mended values and rule out any liability. They constitute no general war- ranty of quality and condition. The user must determine from case to case whether a product is suitable for the intended use.
