End discs are structural components that form the outer circular plates of drive pulleys, providing mounting surfaces and structural integrity for belt contact surfaces.
End discs are precision-engineered circular plates that constitute the outermost structural elements of drive pulleys in power transmission systems. These components serve as mounting platforms for pulley hubs and provide the foundational structure for belt contact surfaces. They distribute mechanical loads evenly across the pulley assembly, maintain concentricity during rotation, and ensure proper belt alignment. End discs are typically manufactured with specific dimensional tolerances to accommodate bearing assemblies, shaft connections, and belt groove configurations.

End discs serve as structural support elements that provide mounting surfaces for pulley hubs, distribute mechanical loads evenly, and maintain the geometric integrity of the pulley assembly during operation.
Material selection impacts load capacity, corrosion resistance, weight, and durability. Steel offers high strength for heavy loads, aluminum reduces weight for high-speed applications, and stainless steel provides corrosion resistance in harsh environments.
Common failures include fatigue cracking from cyclic loading, deformation from excessive torque, corrosion in aggressive environments, and mounting hole wear from improper installation or vibration.
