AR48 Rubber Coupling Description

The YNF17797 AR48 Coupling Rubber is a heavy-duty flexible coupling insert used between diesel engines and hydraulic pumps in excavators and construction machinery. Compared with smaller coupling models, the AR48 coupling is designed to handle higher torque and load, making it suitable for medium to large excavators and industrial hydraulic systems.

Manufactured from premium oil-resistant and fatigue-resistant rubber, this coupling insert effectively absorbs torsional vibration, compensates for minor shaft misalignment, and reduces impact loads during startup and operation. By minimizing vibration and shock, it helps prevent premature wear of pump bearings, shafts, and engine output components.

Widely used by professional repair workshops and aftermarket distributors, the YNF17797 AR48 coupling rubber ensures smooth power transmission, reduced noise, and extended service life of hydraulic pump drive systems.
