The term "silentblock" comes from "silent," meaning quiet, and "block," meaning to block or secure. These are used as bumpers or damping elements where it is necessary to limit the transmission of vibrations from one part to another. They are designed to function without lubrication and maintenance. However, these components also have a lifespan, and over time, they will need to be replaced because they are mostly made of rubber, which loses its properties due to operational conditions and environmental factors.
