Custom Industrial Gear Flexible Flange Shaft Coupling Manufacturer For Mining Machinery – Henan Sankuang Machinery 

Henan Sankuang Machinery Technology Co., Ltd. is a professional Chinese coupling manufacturer integrating casting, CNC machining, heat treatment and complete quality testing, serving global heavy machinery clients especially buyers from Russia, Central Asia and Eastern Europe.We supply full series couplings: gear coupling, flexible coupling, flange coupling, universal coupling, drum gear coupling, rigid coupling, all can be customized by torque, rotation speed, shaft diameter and installation size according to clients’ drawings and samples. Complete Production Equipment & Closed-Loop Process Our factory owns more than 140 sets advanced machining equipment including CNC lathes, gear hobbing machines, grinding machines, heat treatment furnaces and spectral inspection instruments. The full production flow covers raw material inspection → casting/forging blank → rough machining → finish precision processing → carburizing & quenching heat treatment → dimensional grinding → assembly test → finished product comprehensive inspection. Every processing step has independent QC personnel for tracking to control precision and hardness steadily. Strict Quality Control System All raw steel materials pass spectral analysis before production. During processing, we carry out roundness, concentricity, hardness and torsion testing for semi-finished products. Finished couplings will complete load and fatigue resistance simulation test before delivery. We support third-party inspection and provide complete inspection reports for Russian customs clearance. Custom & Global Export Service We accept OEM & ODM customization for non-standard couplings used in mining, metallurgy, construction, port machinery. Stable export channels to Russia with FCA trade terms and TT payment support. Our professional Chinese-English-Russian sales team provides one-stop technical drawing optimization, production tracking and after-sales service.
