140 Series Heavy-Duty Agricultural & Truck Drive Shaft Assembly

Welded Telescopic Cardan Universal Joint Shaft for Farm Machinery & Industrial Vehicles

The 140 Series Drive Shaft Assembly is a high-strength, precision-engineered universal joint shaft designed for agricultural machinery, light-to-medium trucks, and industrial equipment drive lines. Built with high-grade forged steel yokes, cold-rolled seamless steel tubing, and an overall quenched telescopic spline shaft sleeve, this drive shaft delivers outstanding impact resistance, high torque capacity, and smooth axial displacement. Engineered to withstand demanding farm field operations and heavy dynamic loads, it ensures stable, long-lasting power transmission with minimal maintenance downtime.

Key Advantages & Features

• Optimized for Agricultural Machinery & Vehicles: Ideal power transmission component for tractors, harvesters, PTO shafts, and light truck drive systems.
• Special Cold-Rolled Seamless Steel Tube: Constructed from thick-walled seamless steel pipe, ensuring exceptional torsional rigidity, resistance to bending, and smooth rotational balance.
• Quenched Spline Shaft Sleeve: Spline components undergo full-body quenching heat treatment to minimize rotational play, dramatically increase wear resistance, and extend service life.
• High Torque & Load Bearing Capacity: Heavy-duty forged steel cross yokes absorb peak torque loads and severe shock impacts during heavy agricultural operations.
• Anti-Corrosion Protective Coating: Finished with a durable anti-rust spray paint coating (standard colors available in Orange and Black) to withstand outdoor moisture, mud, and harsh weather conditions.
• Broad Standard Length Availability & Customization: Available in widespread pre-fabricated length specs (220mm, 280mm, 320mm, 355mm, 380mm, 400mm, 430mm, 490mm, 550mm, 1160mm, etc.) as well as non-tubing weld end options (e.g., Weld Port 81 / 84).
