Procedures/testing Details
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.
