WHY SIDEM
SILENT BLOCKS?
Due to the forces that are constantly acting on silent blocks, their strength is key. That’s why we provide silent blocks with excellent rubber quality and impeccable metal-to-rubber bonding properties.
To have our silent block’s spot on, we test them in every possible way. Stiffness, flexibility and Shore hardness are vital properties for your driving comfort and stability. Leave that to us!
As mounting a silent block correctly is very important for its lifespan, we’ll help you out! A QR-code on our package leads you towards our mounting instructions, clarifying things for you.
Silent blocks, also known as suspension bushings, play a crucial role in a vehicle’s suspension. Their main purpose is to absorb vibrations, noises and impacts while driving, preventing them from being transferred to the body and interior. Silent blocks are important to have a perfect driving comfort.
Basically, you could divide silent blocks in 2 main categories:
- Static silent blocks have the sole purpose of absorbing vibrations, noise and impacts, providing comfort to your drive. Otherwise, they are not designed to move or pivot. Typical static silent blocks are chassis bushings, which connect the chassis to the vehicle body.
- Dynamic silent blocks have a second purpose: to act as a pivot, allowing movements of other parts. Typical examples are the silent blocks in the track control arms which are mounted to the chassis. They have the purposes of both cushioning the connection while allowing the track control arm to tilt.
A lot of forces act on silent blocks constantly: the weight of the vehicle; acceleration and deceleration; braking; impacts; … Therefore, their strength is crucial! Still, the correct balance with flexibility for your comfort is needed.
A silent block also can’t be too flexible, as they have a direct impact on your wheel alignment and driving stability! Different designs exist to allow more flexibility/comfort in one direction while maintaining the required stiffness in the other.
