3556001 SB5, SN5 Optional and Dust Bellow - MERCEDES BENZ

This heavy-duty grade component serves as a critical part within the air disc brake system, specifically functioning as an optional and dust bellow for the brake caliper tappet. Designed to protect internal mechanisms from environmental debris, it ensures the consistent movement and longevity of the braking assembly under demanding operational conditions.

3556001 is the OE-equivalent of the KNORR-BREMSE II370760065 and MERCEDES BENZ 000 420 13 82 used in MAN TGL and TGM heavy commercial vehicles. This part is engineered to meet the exact specifications required for compatibility with KNORR-BREMSE SB5 and SN5 systems, providing a seamless fit for professional workshop applications.

For workshop technicians, this component is essential during brake caliper maintenance and overhaul. Given its Ø 74 mm diameter specification, it must be installed with precision to maintain optimal pneumatic-mechanical interaction. Regular inspection of the bellow's integrity is recommended to prevent dust ingress from affecting the caliper piston movement or braking performance.
