High-Performance Friction Discs for ZF Transmissions

Precision Fit: ZF 4642-308-330
Engineered to exceed ZF 4WG200 transmission specifications, our friction discs deliver optimal torque transfer and heat resistance (up to 580°C) under extreme loads in construction and agricultural machinery. Utilizing ceramic-embedded bronze composites, they reduce vibration noise, prevent thermal glazing, and maintain stable friction coefficients (μ=0.41±0.02) across diverse operating conditions. Rigorously validated for compatibility with ZF, Komatsu, Caterpillar, Volvo, and JCB systems via ISO 9001 & IATF 16949 protocols1.

Cross-Industry Applications

• Earthmoving Equipment: Loaders (e.g., CAT 966M), excavators (Komatsu PC300), compactors.

• Agricultural Machinery: Tractors (John Deere 5075E, YTO-1004) and harvesters in high-dust environments.

• Material Handling: Forklifts (Toyota 8FD), port cranes, and mining conveyors.

• Critical Advantage: Wave-cut surface patterns enhance oil flow, reducing wear by 35% vs. standard discs.

Technical Superiority & Customization

• Direct ZF Replacement: Identical dimensions to ZF 4642-308-330 – seamless integration1.

• Advanced Materials: Sintered bronze matrix with Kevlar reinforcement for RoHS/REACH compliance.

• Tailored Solutions: Modify thickness (4.0mm ±0.03mm), groove geometry, or hardness (62–65 HRC).

• Quality Assurance: Batch testing reports and 24-month warranty included.
