The silent block is a special vibration isolator made of two metal bushings inserted into each other and an elastomeric (rubber) insert between them. The main feature of this vibration isolator is a durable permanent connection between the elastomer and the metal obtained during the vulcanization process, due to which there is practically no friction force between them. The unit is designed to damp radial, torsion and axial vibrations. In other words, the silent block connects the car's suspension parts, in particular the suspension arm and the body, and, due to the rubber insert, reduces vibrations between them.

The principles of the SWAG brand Mounting, axle beam usage

This detail is present both on the front suspension and on the rear. In the first case, the front arm silent block connects the car body and the front suspension arm, and in the second - the beam arm with the body. The degree of damping of vibrations is determined by the quality of the elastomer: the best damping of vibrations is elastomers based on natural rubber.
