This article provides a comprehensive comparison between dry and wet friction discs, two fundamental types used in power transmission and braking systems. It details their distinct operating environments: dry discs function in air-cooled settings (e.g., manual clutches, brakes), while wet discs operate submerged in oil (e.g., automatic transmission clutches). The guide contrasts their material compositions, such as ceramic/sintered metals for dry applications and paper-based/sintered bronze materials for wet systems. It further explains how performance is analyzed—through torque characteristics and heat management—and offers a clear selection framework based on application requirements like engagement smoothness, heat dissipation, and system complexity. This resource is essential for engineers, procurement specialists, and technicians making informed decisions about friction components.
