Final Drive & Swing Components
Planetary drive gears must withstand the high forces of torque generated by the engine and transfer these loads to move the equipment. All CTP swing gears and final drive gears are manufactured to precise tolerances for reliable operation. The manufacturing method includes a heat treatment process that increases bending strength, prevents case crushing and provides exceptional wear resistance for a long service life.
