Cat Friction Disc (Planetary)

Cat drivetrain components must endure incredible torque, high impact loads and frequent direction changes. Cat designs their components with these demands in mind. The result is a drive train that works harder over the life of the machine. Cat friction discs are designed to work with braking systems, providing critical friction to slow, stop, or hold a machine stationary.
