Quality & Process

Quality Inspection

Bearings are tribological components that carry a load while in contact with and moving relative to another part, which is an indispensable part of the machining and installation process

Production Process

Following let us show several specific processes of bearing manufacturing:
★①.Raw material quality control: Inspection report of raw materials.
★②.Melting formula: Ensure the exact formula ratio to ensure the stability of bearing performance basing on customer’s detailed requirement.
★③.Spectroscopic analysis: Only when spectroscopic analysis of sample is qualified, bearing casting can be carried out. Samples will be kept for 3 years with traceability.
★④.Dimensional inspection: Precision measuring tools and CMM coordinate measuring machine are used to ensure the precision of bearing.
★⑤.Defect check: Bearing appearance test. Ultrasonic Testing / PenetrantTesting will be carried out according to customer's requirements.
★⑥.Factory test report is available for every bearing. Third party testing reports can be provided when required.
