High-Performance Friction Discs for Extreme-Duty Applications

Precision Engineered: ZF 4474-252-008
Designed to exceed OEM specifications, our friction discs ensure optimal torque transfer and thermal stability (up to 550°C) under heavy loads in construction, agriculture, and material handling equipment. Utilizing graphite-infused ceramic composites, they reduce noise, prevent glazing, and maintain consistent friction coefficients (μ=0.38–0.42) across diverse operating conditions. Rigorously validated for compatibility with Komatsu, Caterpillar, JCB, Volvo, John Deere, and ZF transmissions via ISO 9001 and IATF 16949 testing protocols15.

Cross-Industry Compatibility & Reliability

• Earthmoving Equipment: Ideal for excavators (e.g., Komatsu PC360), loaders (CAT 950G), and compactors.

• Agricultural Systems: Optimized for tractors (John Deere 7R, YTO-1204) and harvesters under high-moisture conditions.

• Material Handlers: Seamless fit for forklifts (Toyota 8FD), mining shovels, and port cranes.

• Critical Advantages: Laser-etched cooling grooves enhance heat dissipation, extending service life by 35% vs. standard discs58.

Technical Excellence & Customization

• Zero-Compromise Fit: Exact dimensions match ZF 4474-252-008 – no modifications required5.

• Advanced Materials: Asbestos-free sintered metal matrix with bronze additives for wear resistance and eco-compliance9.

• Tailored Solutions: Modify groove patterns, thickness (4.8mm ±0.05mm), or hardness (58–62 HRC) based on operational demands58.

• Global Certifications: Meets EU Machinery Directive 2006/42/EC and ANSI/AGMA standards for safety and performance7.
