GRTECH has achieved another major breakthrough in the mass production of heavy-duty commercial vehicle transmission components. A total of 250,000 pieces of self-developed 430mm high-performance clutch facings have completed full-process precision production, strict performance testing and standardized packaging. The entire batch is now fully stocked at the Yiwu warehouse and ready for batch dispatch to global markets, covering overseas heavy-duty truck, engineering vehicle and passenger bus supporting and after-sales maintenance markets.
Different from small and medium-sized machinery clutch products, GRTECH's 430mm high-performance clutch facings are specially developed for heavy-load commercial vehicle operating scenarios, adapting to long-distance high-speed driving, frequent start-stop shifting, and high-torque overload operation of heavy trucks, large buses and engineering machinery. The product adopts upgraded ceramic fiber composite friction formula, abandoning traditional single organic friction materials, and integrates high-temperature resistant, wear-resistant and anti-aging raw materials. It achieves ultra-stable friction coefficient within the extreme temperature range of -40°C to +350°C, effectively solving the problems of friction attenuation and power transmission failure caused by long-term high-load operation of heavy vehicles.
In terms of structural and craftsmanship optimization, this series of clutch facings adopts integral one-piece die-casting and precise laser cutting forming technology, with uniform thickness and flat surface without deformation. The optimized radial heat dissipation groove structure greatly improves active heat dissipation efficiency, reduces continuous operating temperature by about 25°C compared with ordinary products, and effectively avoids thermal ablation, glazing and premature wear of friction materials under long-hour continuous working conditions. Meanwhile, the product is equipped with high-precision hole position calibration technology, which perfectly matches mainstream 430mm clutch assembly structures of commercial vehicles, ensuring zero assembly error and excellent fitting compatibility.
In terms of comprehensive durability and driving experience, the 430mm clutch facings feature low inertia and flexible friction response. They realize smooth and stable clutch engagement and disengagement, effectively suppress transmission vibration and abnormal noise, eliminate gear shifting jitter, and significantly improve vehicle driving comfort and transmission stability. Test data shows that the product's anti-fatigue service life reaches 7.6 million actuations, with overall wear resistance and high-temperature durability 40% higher than ordinary industry-standard clutch facings, greatly extending the replacement cycle and reducing the overall operating and maintenance costs of commercial vehicles.
All products comply with international commercial vehicle OEM quality standards and heavy-duty parts industry certification specifications. They have passed multiple extreme condition tests including high-temperature fatigue, low-temperature toughness and overload impact resistance. With reliable quality, strong severe-duty adaptability and wide model compatibility, they are suitable for most mainstream heavy-duty trucks, large passenger buses and engineering equipment in European, Asian and Middle Eastern markets, winning consistent recognition from global parts distributors and vehicle manufacturers.
Prior to warehousing, GRTECH implemented full-scale sampling and batch inspection on the 250,000 pieces of clutch facings, covering friction performance, dimensional accuracy, high-temperature resistance and surface flatness, strictly screening unqualified products to ensure 100% qualified rate of delivered goods. Adopting customized dust-proof, moisture-proof and compression-resistant export-grade packaging, the products can resist extrusion and humidity changes during long-distance transportation and cross-border warehousing. Centralized storage in Yiwu warehouse supports flexible batch delivery and quick order response, enabling rapid supply to global after-sales markets and OEM supporting orders.
