HY21-212 Propeller Shaft for Heavy Trucks

The HY21-212 Propeller Shaft is a compact, high-performance drivetrain component meticulously engineered for heavy-duty trucks, designed to reliably transmit torque from the transmission to the 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 heavy-load operations and extended service life.

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

A Flange Yoke with 50×62 dimensions and 60mm protrusion, featuring a 4-hole square flange interface that forms a secure, rigid connection to the axle or differential. This design maximizes load-bearing capacity and ensures consistent power transfer, effectively preventing loosening or slippage under heavy loads.

A 30×88 Universal Joint (Cardan Joint), a heavy-duty cross joint that accommodates angular misalignment between the transmission and 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.

Manufactured with strict dimensional tolerances, the HY21-212 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 propeller shaft is ideally suited for heavy-duty commercial vehicles, including compact heavy trucks, dump trucks, and engineering vehicles, 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.
