QC/Technical Support
The QC department of L&Z Bearings is fully equipped with all the necessary testing and inspection facilities, including measuring gauges, on-line inspection devices and the numerous instruments for testing bearing functional performance. We also have experienced professional inspectors and engineers guided by a ISO 9001:2000- and ISO/TS 16949:2002-certified quality management system.

Some QC instruments and meters are sourced domestically, and some are imported from the UK, Japan and Germany.

All raw materials and components are subject to rigid metallurgical tests and only qualified materials are used. All components processed in every manufacturing stage are inspected and tested strictly. All our components are cleaned after grinding, and all the finished products are cleaned and dried several times. 100 percent inspection and testing is carried out before packing, including noise and vibration testing, radial and axial clearance inspection.
