Bearing failure analysis
CHG has professional testing tools and rich practical experience to test and analyze various bearing performance parameters, and perform dimensional inspection by using a video microscope, including roundness, raceway radius and surface roughness (Ra), hardness, torque and digital noise / Vibration, we can analyze the failure of your bearings, be able to isolate and identify the root cause of early failures, and guide customers to take preventive measures. If you would like CHG to help determine why any of your bearings have failed to meet your performance or life expectancy expectations, please contact us
Fatigue Failure-Usually characterized by spalling or flaking of the raceway. Fatigue failure refers to the fatigue failure of the material caused by the alternating working stress of the bearing working surface. Contact fatigue spalling occurs on the bearing working surface, which is often accompanied by fatigue cracks. It first occurs from the maximum alternating shear stress below the contact surface, and then expands to the surface to form different spalling shapes.
