Quality Control

According to ISO / TS16949, ISO9000 Quality Management System, CQC Management System requirements and customer requirements, we keep the quality promise, quality control strictly,  improving customer satisfaction.

The QC department have measuring gauges, on-line inspection devices and numerous instruments for testing bearing functional performance. Testing details: All raw materials and components are tested and only qualified materials are used; All components processed in every manufacturing stage are inspected and tested strictly; 100 percent inspection and testing is carried out before packing, including noise and vibration testing, radial and axial clearance inspection.
