Track, Wheel, And Slew Drive Differences

Track, wheel, and slew drives all use planetary reduction, but their output support, mounting, load path, and control requirements are different.

Track Drives

Track final drives commonly integrate with hydraulic motors and a rotating housing flange. Selection focuses on tractive effort, sprocket geometry, gradeability, travel speed, shock load, and parking brake requirements.

Wheel Drives

Wheel drives place the reduction close to the wheel or drum. Vehicle mass, wheel radius, drawbar pull, axle load, speed, and available hub space are key inputs.

Slew Drives

Slew drives rotate a structure rather than propel a vehicle. Rotating inertia, external wind or slope torque, brake duty, output pinion geometry, and overturning loads become central.

Replacement Data

For any mobile-drive replacement, provide the original model, motor interface, bolt circles, pilot diameters, output connection, brake information, and photos.
