Advanced Friction Discs for Heavy Machinery

Precision Engineered: ZF 4474-352-052
Manufactured to surpass OEM standards, our friction discs deliver unmatched torque transmission and thermal stability (up to 600°C) for construction, mining, and agricultural equipment. Utilizing graphite-reinforced ceramic composites, they minimize noise, eliminate glazing, and maintain consistent friction coefficients (μ=0.40±0.02) under extreme conditions. Validated for seamless compatibility with Komatsu, Caterpillar, JCB, Volvo, John Deere, and ZF transmissions through rigorous ISO 9001 and IATF 16949 testing1.

Cross-Industry Applications

• Construction & Mining: Excavators (e.g., Komatsu PC400), loaders (CAT 980G), and compactors in abrasive environments.

• Agricultural Systems: Optimized for tractors (John Deere 9R, YTO-1604) and harvesters under high-moisture and dust exposure.

• Material Handling: Forklifts (Toyota 10FD), port cranes, and conveyor systems requiring precise clutch engagement.

• Critical Advantage: Laser-engraved radial grooves enhance heat dissipation, extending service life by 40% versus conventional discs.

Technical Superiority & Custom Solutions

• Exact OEM Fit: Direct replacement for ZF 4474-352-052 – zero retrofitting needed.

• Eco-Compliant Materials: Asbestos-free sintered bronze matrix with ceramic additives, meeting RoHS and EU directives1.

• Tailored Engineering: Adjust thickness (5.2mm ±0.05mm), groove patterns, or surface hardness (60–64 HRC) based on operational demands.

• Quality Assurance: Full traceability with batch certification and 18-month warranty.
