228703787 pin assembly XCMG XS135 road roller spare parts

This 228703787 pin assembly is specially matched for XCMG XS135 vibratory roller mechanical connection structure. Adopting high-precision alloy steel forging and overall quenching and tempering heat treatment process, it features high surface hardness, strong wear resistance and excellent bending and shear resistance. As the key movable connecting part of the roller, it undertakes the hinge transmission and flexible rotation of working components. It can adapt to long-term cyclic vibration, frequent swing and variable load working conditions during compaction operation, effectively avoiding structural jamming, connection looseness and component deflection. With precise machining tolerance and good fit clearance, it ensures smooth and consistent action coordination of mechanical mechanisms, reduces equipment running noise and mechanical wear, and supports long-term stable heavy-duty operation of the whole machine.
