3556018 SN6, SN7, SK7 Optional and Dust Bellow

The technical function of this component is to provide essential protection and stability within the braking system. As an optional and dust bellow for the brake caliper tappet, it ensures that the mechanical movement remains unobstructed by environmental debris, maintaining consistent braking performance under heavy-duty conditions.

3556018 is the OE-equivalent component used in the KNORR-BREMSE SN6, SN7, and SK7 systems. This part is engineered to meet strict technical requirements for heavy commercial vehicle braking assemblies, ensuring seamless integration with existing hardware.

For workshop technicians performing maintenance or repairs, this part is designed for precise fitment within the caliper assembly. It is vital to ensure that the installation follows standard service protocols to maintain the integrity of the pneumatic braking system. Regular inspections of the bellows and tappet area are recommended during routine vehicle servicing to prevent dust ingress and ensure long-term durability.
