Quality Assurance & Manufacturing Excellence
At Henan San Kuang Machinery Technology Co., Ltd., we operate under a comprehensive quality management system certified to ISO9001, ISO14000, and OHSAS18001. Our factory uses advanced CNC machining centers, induction hardening equipment, and precise measuring instruments. Every bearing undergoes dimensional inspection, hardness testing, and non-destructive testing (e.g., magnetic particle inspection) to ensure defect-free performance. The mill test report, included with each shipment, provides chemical composition and mechanical properties of the steel used. Combined with full traceability, you can trace the bearing back to its heat number and manufacturing batch.
