Cat® Axle Yokes are designed to allow rigid shafts to be joined about a spider structure to transmit rotary motion to the wheels or tracks. They are manufactured using special, and in some cases proprietary, heat treat processes including case carburizing, nitriding, and induction hardening. Cat® yokes have the industry's highest power density, or the amount of power a yoke 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® 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. Application:Cat® Yoke is used to transmit rotary motion in the front axle on Cat® Machines.
