AZ2212100003 planetary gear shaft is a core load-bearing component of the transmission planetary mechanism. It is precision forged from high-strength alloy material and integrally strengthened by quenching and tempering treatment, featuring high rigidity, excellent bending and torsion resistance, and free from bending and deformation under heavy load.
The surface is finely ground with high finish, ensuring smooth operation when matched with planetary gears, low friction loss, outstanding wear resistance and fatigue resistance.
It is compatible with multiple series of Sinotruk transmissions. With original precise dimensions and standard assembly clearance, it avoids looseness and offset under driving vibration. It adapts to complex working conditions such as mountain heavy load and long-distance trunk transportation, featuring strong durability and high compatibility for maintenance and replacement.
