Heavy-Duty High-Precision Slewing Bearing Customization Expert – Henan Sankuang Machinery Technology
In the field of heavy machinery transmission, the slewing bearing serves as the core component for load-bearing and rotation, with its precision directly impacting equipment lifespan. Henan Sankuang Machinery Technology Co., Ltd., rooted in the Luoyang mining machinery industrial cluster, specializes in manufacturing extra-large slewing bearings with outer diameters reaching several meters .
We adopt advanced near-net shape forging technology for rings, combined with induction heating flangeless medium frequency quenching, effectively enhancing raceway surface hardness and wear resistance, solving the problem of early failure in soft zones . Regarding large-sized rollers, we apply logarithmic profile modification to optimize contact stress distribution, significantly improving the bearing’s load capacity and operational stability under combined overturning moments and axial forces .
Whether applied in shield tunneling machines, wind turbines, or port ship unloaders, Sankuang’s slewing bearings are customizable and support processing according to supplied drawings. From forging to the finished product, we implement full-process precision control, ensuring each bearing maintains high reliability and extended longevity in harsh working conditions .
