Description:Cat rotors, such as 588-2812, are designed to work with brake pads in braking systems, providing critical friction to slow, stop or hold a machine stationary.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.Attributes:• Cast iron brake rotor• Mounting Hole Diameter: 18 mm (0.709 in) (10X)• Inside Diameter: 175.08 mm (6.893 in)• Outside Diameter: 438.1 mm (17.248 in)• Width: 65 mm (2.559 in)• Thread: M12 (2X)Application:Consult your owner's manual or contact your local Cat Dealer for more information.
