Common issues in the market for hollow shaft forgings, such as loose internal structure, unstable mechanical properties, and insufficient dimensional accuracy, directly lead to high equipment failure rates and shortened service life. Through strict forging process control and full-process quality inspection, Jianing Forging ensures that every hollow shaft forging has a uniform and fine internal structure and stable mechanical properties, effectively reducing customer equipment maintenance costs.

The hollow shaft forgings produced by Jianing Forging (hollow shaft forging processing) are made from high-quality alloy steel or carbon steel materials, forged through multiple processes including heating, upsetting, punching, reaming, and shaping. The product features uniform wall thickness, high coaxiality of inner and outer circles, and continuous metal streamlines, making it suitable for shaft components under heavy-duty conditions such as mining machinery, wind power spindles, hydraulic plungers, and ship power systems.
Dense structure – Forging eliminates casting defects, with metal streamlines distributed along the force direction, resulting in significantly better fatigue resistance than castings.
Dimensional stability – Strictly controls inner and outer diameter tolerances and roundness, reduces subsequent finishing allowances, and improves material utilization.
Material compatibility – Conventional or custom grades such as 45#, 40Cr, 42CrMo, 35CrMo, 20CrMnTi can be selected to meet different strength and toughness requirements.
Flexible specifications – supports non-standard customization within an outer diameter of 200mm~2000mm and a length of 300mm~8000mm, meeting special installation space requirements.
Hollow shaft forgings are customized products, and the final price must be comprehensively calculated based on material grade, dimensional specifications, heat treatment requirements, quantity, and other factors. Please provide specific drawings or technical parameters, and we will provide you with a relatively accurate quotation.
All products undergo ultrasonic flaw detection (UT) and dimensional inspection before leaving the factory, and inspection reports are provided.
Supports three modes: blank delivery, rough processing delivery, and fine processing delivery, reducing customers' secondary processing steps.
The after-sales technical team responds 24×7 hours a day, and offers free process optimization advice for non-standard products.
