Import Brake Lining, Heavy Duty Lining, 4551 — Buy in wholesale FOB from Supplier in China

The FMSI4551 brake lining from Tough Pro Group Limited is a non-asbestos friction composite with a ceramic-metallic blend, engineered specifically for heavy duty truck drum brake systems. The part carries FMSI reference 4551 and cross-references DRUM419, with dimensional set A measuring 194.6 by 189.1 millimetres, set B at 219.1 millimetres, and set C at 17.6/11.1 to 18.2/15.2 millimetres. This lining is designed as a direct replacement OE-quality component compatible with Volvo, SAF, ROR, SMB, and ME axle assemblies, among others including MAN, Scania, BPW, and Dana. The manufacturer states the material is environmentally friendly and offers high temperature resistance, backed by ISO/TS 16949:2009 certification and Greening Test compliance.

The ceramic-metallic blend in this friction material is typical for modern heavy duty applications where thermal stability and wear resistance must balance against drum compatibility and noise suppression. Non-asbestos organic (NAO) formulations with ceramic additives generally operate effectively across temperature ranges from -40°C to 350°C, with typical friction coefficients between 0.35 and 0.45 depending on operating conditions. Industry standard厚度 (thickness) for this FMSI profile typically falls within 17-18 mm, with width tolerances of ±0.5 mm to ensure proper drum clearance and even pressure distribution. The rivet hole patterns follow SAE or OEM specifications to match existing brake shoes without modification.

Fleet operators, independent aftermarket distributors, and commercial vehicle parts importers represent the primary buyers for this SKU.
