This output shaft rear end cover is integrally cast from high-strength cast iron with a dense structure and high rigidity, delivering excellent compression resistance and deformation resistance. It can withstand the axial impact generated during heavy-duty operation of the gearbox.

Precision machined with strict tolerances for mounting hole diameters and spigot dimensions, it achieves a high sealing fit and effectively prevents oil seepage and leakage.

It features corrosion resistance and aging resistance, adapting to long-term complex road conditions and high-low temperature working environments. It reliably protects core internal components such as bearings and gears while offering good shock absorption and noise reduction. Compatible with mainstream Sinotruk gearboxes, it provides perfect vehicle fitting and long-lasting durability.
