Free Forged Intermediate Shaft for Industrial Drive Train Systems

Free Forged Intermediate Shaft for Industrial Drive Train Systems. Our free forged intermediate shafts are engineered to withstand high torque transmission and fluctuating loads in industrial drive train systems. Manufactured from high-performance alloy steels like 42CrMo and 20CrMnTi, these shafts deliver superior mechanical strength, fatigue resistance, and long-term reliability in demanding environments such as mining, metallurgy, wind energy, and heavy machinery.

Key Features:

• Material Options: 42CrMo, 20CrMnTi, 45# — providing excellent tensile strength, toughness, and hardenability for rotational applications under dynamic torque.

• Forging Process: Open-die (free) forging ensures directional grain flow along the shaft axis, minimizing internal flaws and enhancing torsional strength and impact resistance.

• Precision Machining: Capable of producing stepped profiles, splined ends, keyways, and flanged sections according to customer drawings and tolerances.

Typical Applications:

• Intermediate shafts in heavy-duty gearboxes and transmission assemblies

• Torque transmission systems for mining, marine propulsion, and steel rolling equipment

• Power take-off and drive shafts in large mechanical or hydraulic equipment

The steel forgings production flow:

Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
