One New Aftermarket Replacement Coupling for Caterpillar (Cat) Excavators
This coupling is used in the final drive assembly of Caterpillar (Cat) medium and large excavators. It connects the hydraulic motor shaft to the planetary gear assembly, transmitting torque and power to drive the tracks. The coupling also compensates for axial, radial, and angular displacement caused by manufacturing tolerances, thermal expansion, and mechanical vibration, helping protect the final drive from premature wear.
