Made of quenched and tempered alloy steel with precision gear grinding, featuring ultra-small coaxiality error and smooth meshing to resist torsional deformation under bumpy heavy-load conditions and reduce gear noise effectively. Carburizing and quenching enhances surface wear resistance against shaft breakage during long-hour heavy-duty operation. Direct OEM replacement fits ZF12S2230 and ZF16S221 transmissions, extending service life of auxiliary planetary reduction assembly and cutting breakdown maintenance cost.
6093304079 Pinion Shaft
Made of special alloy for heavy machinery via overall quenching and tempering plus precision gear grinding with high tooth precision and structural rigidity to withstand frequent power impacts and avoid bending or shaft fracture under heavy load. Surface strengthening improves wear and fatigue resistance to eliminate abnormal noise caused by excessive meshing clearance. It is interchangeable with original parts for ZF12S2230 and ZF16S221 transmissions, improving transmission efficiency and service life of planetary reduction assembly.
