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

Item Details
Product Name Free Forged Intermediate Shaft for Industrial Drive Train Systems
Material Grades - Alloy steel: 42CrMo, 20CrMnTi - Offers high tensile strength, excellent fatigue resistance, and good hardenability under heavy-duty torque transmission
Forging Equipment - Hydraulic hammers: 5T / 8T / 12T- 3600T open-die forging press for long, stepped, or flanged shaft forgings- Capable of forming complex shaft geometries with splines, journals, flanges, and keyways
Manufacturing Process Hot Forging → Heat Treatment → Ultrasonic Testing → Rough / Semi-Finish Machining → Final Dimensional & Surface Inspection
Forging Ratio ≥ 3.0 — This forging method promotes an aligned grain structure along the shaft axis. This isn't just a technical detail; it directly enhances torsional strength, improves impact resistance, and significantly boosts the operational longevity of the component. It means your shafts are built to last longer and perform better under extreme stress.
Applications - Intermediate shafts in gearboxes and industrial drive train systems- Torque transfer shafts in mining, wind turbine gear trains, and metallurgy- Power transmission components in heavy-duty construction and marine machinery
Heat Treatment Options - Quenched + Tempered for high strength, wear resistance, and fatigue endurance- Normalizing for grain refinement and improved dimensional control- Optional stress-relief annealing to reduce internal stress and machining distortion
Testing & Inspection - Chemical: Alloy composition checked by spectrometer- Mechanical: Tensile, yield, hardness, and Charpy impact tests (axial & transverse)- Ultrasonic (UT): 100% internal flaw detection- Dimensional: Runout, straightness, diameter tolerance, concentricity, and surface roughness
Value-Added Services - Machining of splines, threads, journals, and keyways to drawing- Surface treatments such as anti - Export packaging for land/sea freight- Full material traceability: heat number, batch number

 

 

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.
