Friction Disc Introduction
Friction Disc is precision manufactured from premium C93200 SAE 660 bronze, also known as bearing bronze, delivering exceptional performance in demanding industrial applications. Our friction discs are produced using advanced centrifugal casting technology, ensuring uniform density and superior mechanical properties throughout the component.
C93200 SAE 660 bronze friction discs offer excellent wear resistance, high load capacity, and superior anti-friction characteristics. This alloy contains optimal proportions of copper, tin, lead, and zinc, providing the perfect balance of strength, ductility, and machinability required for reliable friction performance.
Each parts from Leesh undergoes rigorous quality control to meet international standards and customer specifications. The centrifugal casting process enhances the material’s integrity, eliminating porosity and ensuring consistent hardness and wear properties across the entire disc surface.
We understand that different applications have unique requirements. Our Disc can be customized with adjusted material compositions to optimize performance for specific operating conditions, including temperature, load, and speed parameters. Trust our expertise to deliver high-quality friction discs that provide reliable service and extended operational life in your machinery.
