WG2203100254 High-speed Cone Hub Assembly is applicable to the auxiliary gearbox of Sinotruk Howo HX25712 series gearboxes and fits various heavy-duty freight and engineering vehicles.

It is integrally forged from high-strength alloy steel. The cone surface and gear body are quenched and hardened, featuring wear resistance, high temperature resistance, impact resistance and anti-deformation performance.

Precision CNC machining ensures high coaxiality and perfect fitting with the synchronizer ring, enabling smooth high gear shifting without jamming or gear knocking noise.

Manufactured strictly in accordance with original factory dimensional standards, it offers excellent interchangeability and easy installation. It performs outstandingly stable under high-intensity working conditions such as mines and national highways, effectively reducing gearbox failures and maintenance frequency.
