In heavy machinery and transmission systems, the durability and precision of shaft-type forgings directly affect the stability of equipment operation. Many users have encountered downtime and maintenance issues caused by shaft journal wear, fatigue fracture, or insufficient fit tolerances, which not only increases operating costs but also affects overall production efficiency. The large-head shaft forgings provided by Jianing Forging enhance the fatigue strength and dimensional stability of part
In heavy machinery and transmission systems, the durability and precision of shaft-type forgings directly affect the stability of equipment operation. Many users have encountered downtime and maintenance issues caused by shaft journal wear, fatigue fracture, or insufficient fit tolerances, which not only increases operating costs but also affects overall production efficiency. The large-head shaft forgings provided by Jianing Forging enhance the fatigue strength and dimensional stability of parts through optimized forging processes and strict quality control, helping you fundamentally reduce the risk of failure and extend equipment service life.
Big-head shaft forgings are special-shaped shaft forgings specifically designed to withstand heavy loads, impact, and alternating stress conditions. The product is made from high-quality alloy steel through free forging or die forging. The large end can be processed as needed for flanges, steps, or special-shaped end faces, meeting fine fit with gears, couplings, bearings, and other components. Jianing Forging is equipped with large forging presses and heat treatment production lines, enabling one-stop processing from raw materials to finished products, helping products have a dense internal structure, complete streamlines, and stable overall mechanical properties.
High Load Capacity: After forging, heat treatment such as normalizing and quenching and tempering ensures uniform hardness distribution, allowing it to withstand high-frequency alternating loads and impact loads.
Controllable dimensional accuracy: Equipped with CNC turning and milling equipment, key tolerances such as coaxiality at the large end and end face runout can be controlled within 0.05mm.
Flexible material compatibility: various alloy steels such as 45#, 40Cr, 42CrMo, 35CrMo, 20CrMnTi can be selected, customized according to working condition requirements.
Full-process traceability: Every forging comes with material proof, heat treatment curve, and non-destructive testing report, ensuring quality traceability.
Large-head shaft forgings are non-standard custom products, and the actual price depends on factors such as material grade, finished product dimensions, tolerance requirements, and heat treatment methods. Jianing Forging offers free technical evaluations and drawing optimization suggestions. Feel free to provide detailed requirements or drawings for exclusive quotes.
Technical Consultation: Structural engineers assist with material selection and process design to avoid stress concentration and machining difficulties.
Delivery Support: Specify delivery dates based on order complexity; overdue payments are waived.
Quality Support: Products are managed under the ISO 9001 system, with full inspection of key dimensions and third-party testing reports.
After-sales support: Free resupply within 30 days of arrival for size discrepancies or material defects, with long-term technical assistance.
