Description:Cat drive train components must endure incredible torque, high impact loads, and frequent direction and gear changes. Cat designs and manufactures its transmissions and final drive components with these demands in mind. The result is a drive train that lasts longer and 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.Attributes:•Single spiral grooves and 12 axial grooves for optimized cooling.•Friction material on each face.•Hardened steel•Internal splineApplication:Cat friction discs are used as part of the braking system to reduce rotational speeds.
