Free Forging Custom Forged Shaft Transmission Shaft For Heavy Equipment

Free Forging Custom Forged Transmission Shaft For Heavy Equipment. This transmission shaft is produced through free forging, offering outstanding mechanical strength, structural integrity, and flexibility in size customization. Designed for heavy equipment and industrial power transmission systems, the shaft is made from high-grade alloy or carbon steel, such as 42CrMo, 4140, or 45#, ensuring excellent fatigue resistance and durability under heavy loads.

Free forging allows for the production of large, non-standard shafts with complex shapes and customized dimensions, making it ideal for construction machinery, mining equipment, port systems, and gear-driven industrial applications.

Key Features:

• Forging Type: Open die / free forging

• Material Options: 42CrMo, 4140, 45#, or as specified

• Application: Heavy machinery, gearboxes, drive systems

• Condition: Forged + Rough or finish machined + Heat treated

• Customization: Length, diameter, splines, keyways, profiles per drawing

Advantages:

• Superior grain flow and internal quality

• Flexible sizing for oversized or non-standard parts

• Enhanced performance under high torque and impact loads

• OEM/ODM support with full inspection reports

These are the main inspection equipments:  

We operate a fully equipped in-house laboratory dedicated to mechanical, chemical, and metallurgical testing. This allows us to perform real-time quality checks throughout the entire production process—from raw material selection to final inspection.

Our laboratory testing equipment includes:

Spectral Component Analyzer – for chemical composition analysis

Hydraulic Universal Testing Machine – for tensile and yield strength testing

Impact Strength Testing Machine with Cryogenic Tank – for room temperature and low-temperature impact testing

Brinell & Rockwell Hardness Testers – to assess surface and core hardness

Ultrasonic Flaw Detector – for internal defect detection (UT)Metallurgical Microscope – for grain structure and heat treatment evaluation

Program-Controlled Box Furnace – for heat treatment simulations and metallurgical testing
