They are manufactured using special, and in some cases proprietary, heat treat processes — including case carburizing, nitriding, and induction hardening. Cat gears have the industry's highest power density, or the amount of power a gear can transmit relative to its size and are designed with reusability in mind. Consequently, they are more durable and keep your overall machine operating costs down. Application: Cat gears are built specific to their application to ensure all drive train parts work and wear together as a system. Consult your owner's manual or contact your local Cat Dealer for more information.
