Our Polyurethane Rubber Liner is specially designed to protect the pulley surface of wire saw machines and ensure smooth, stable operation during stone cutting and concrete demolition. Made from high-grade polyurethane elastomer, it offers exceptional wear resistance, flexibility, and strong adhesion to the pulley, greatly extending service life and reducing maintenance frequency. Widely used for stone quarry wire saw machines, granite and marble block cutting, and reinforced concrete cutting systems.
