This aluminum alloy output shaft rear end cover is integrally formed by high-precision die-casting. It is lightweight yet structurally strong, featuring lighter self-weight and superior heat dissipation compared with cast iron versions.

It comes with a standard inner diameter of 13cm and a net weight of 850g. With standard dimensions and precise tolerances, its regular mounting holes fit perfectly with original installation positions.

The surface is treated with oxidation anti-corrosion process for excellent oxidation and rust resistance, resisting deformation and cracking effectively.

The sealing end face is flat and smooth, achieving excellent tightness when matched with oil seals to reliably prevent oil leakage and dust ingress. Compatible with Sinotruk heavy-duty gearboxes, it delivers shock absorption and noise reduction. While realizing lightweight load reduction, it stably protects internal transmission parts and serves a much longer service life.
