HY14-140 Front Propeller Shaft for Heavy Trucks

The HY14-140 Front Propeller Shaft is a high-performance drivetrain component meticulously engineered for heavy-duty trucks, designed to reliably transmit torque from the transfer case to the front axle under extreme load and harsh operating conditions.

Crafted from high-strength alloy steel and finished with a durable black anti-corrosion coating, this propeller shaft delivers exceptional torsional rigidity and wear resistance, ensuring stable performance during long-haul transportation, heavy-load operations, and extended service life.

It integrates three core precision components to guarantee efficient power delivery:

A Flange Yoke with 77×92 dimensions and 95mm protrusion, featuring a 4-hole square flange interface that forms a secure, rigid connection to the front axle or differential. This design maximizes load-bearing capacity and ensures consistent power transfer, effectively preventing loosening or slippage under heavy loads.

A 39×118 Universal Joint (Cardan Joint), a heavy-duty cross joint that accommodates angular misalignment between the transfer case and front axle, enabling smooth and continuous power delivery even on rough, uneven terrain. Its sealed bearing structure with precision-machined bearing caps extends service life and reduces the frequency of routine maintenance.

A Green Center Bearing Support, a robust mounting bracket with a rubber cushion that provides stable support for the propeller shaft, reducing vibration and noise during operation while protecting the shaft from lateral stress.

Manufactured with strict dimensional tolerances, the HY14-140 ensures excellent dynamic balance, minimizing vibration and noise to enhance driving comfort and prolong the service life of surrounding drivetrain components. The anti-corrosion black coating provides reliable protection against rust, moisture, and environmental damage, making it suitable for diverse road and weather conditions, from arid highways to humid construction sites.

This front propeller shaft is ideally suited for heavy-duty commercial vehicles, including 4WD/6WD heavy trucks, off-road engineering vehicles, and mining trucks, where reliable power transmission, durability, and long service life are critical operational requirements. It is engineered to match original equipment specifications for seamless installation and optimal performance, serving as a reliable replacement component for fleet maintenance and repair.
