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.
