Cat® Short Shaft is essentially a drive axle, and it's so named because it does half of the job, extending from a transaxle or differential to one of the wheels. Its twin on the other side completes the set. Cat® Axle components must endure incredible torque, high impact loads, frequent direction and gear changes. Cat® drivetrain axles are designed & manufactured to meet these types of demands. The result is a drive train that lasts longer and works harder over the life of the machine. Axle shaft transmits power from differential to final drive of Cat® heavy duty equipment, and provide excellent driving performance capabilities in demanding conditions.External Straight Cylindrical Gear DataNo. of Teeth : 12Module : 3Pressure Angle : 25Application:Cat® Short Shaft is used to transmit power in Cat® Front Axle.
