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:• Multiple parallel groove pattern optimized for cooling.• Hardened steel core reduces spline wear.• (36) tooth internal spline provides exact OEM fit.• OEM friction formulation maintains brake performance certification.Application:Cat brake friction discs are used as part of the braking system to reduce machine speeds.
