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 disc carriers are designed to work with brake discs in braking systems to slow, stop or hold a machine stationary.Attributes:• Material: Steel• Internal Spline Number of Teeth: 38• External Spline Number of Teeth: 48 (Ref)Application:Cat brake disc carriers are used as part of the braking system to reduce machine speeds.
