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.
