Cat® Gears are machined from carefully selected materials to exacting specifications that match the loads encountered in Cat® machines. 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. Cat® Parts are manufactured to precise specifications and are built for durability, reliability, productivity, less environmental impact, and reuse.Application:Cat® Gears are built specific to their application to ensure all drive train parts work and wear together as a system.
