HY51-120 Propeller Shaft

The HY51-120 Propeller Shaft is a robust power transmission component engineered for light to medium-duty commercial vehicles and industrial machinery, designed to reliably transmit torque between non-collinear shafts while accommodating alignment variations.

Crafted from high-strength alloy steel and finished with a durable black anti-corrosion coating, this propeller shaft delivers exceptional torsional rigidity and fatigue resistance, ensuring stable performance under frequent load cycles and extending service life.

Its double universal joint structure, paired with flange connections at both ends (pitch circle diameter 102, recess depth 70), accommodates angular misalignment between connected shafts, enabling smooth and continuous power delivery. The core component is a precision-machined cross bearing (specification 35×98) with needle roller bearings, which reduces friction and efficiently transmits torque while withstanding dynamic loads. The telescopic middle section allows for axial length adjustment, adapting to variations in vehicle chassis or equipment geometry and simplifying installation.

Manufactured with strict dimensional tolerances, the HY51-120 ensures excellent dynamic balance, minimizing vibration and noise to enhance operational stability and protect surrounding drivetrain components. The anti-corrosion black coating provides reliable protection against rust, dust, and environmental wear, making it suitable for long-term use in diverse operating conditions.

This propeller shaft is ideally suited for light trucks, pickup trucks, and small industrial equipment, where reliable torque transmission, compact design, and durability are critical requirements. It is engineered to match standard interface specifications for seamless installation and optimal performance, serving as a reliable replacement component for vehicle maintenance and equipment repair.
