When removing the damaged bearing

1 Check surface condition of the shaft and the shell hole that matches with bearing and compared with the original design of the technical regulations measuring the surface diameter and roundness check whether there is a micro abrasive wear creep or signs of partial load presence of the trace of the relative sliding.

2 Pay attention to the related parts or adjacent parts whether there is interference with the bearing during operation has obvious phenomenon of wear and tear or corrosion phenomenon find out these parts¡¯s lubricant circulation way and the flying scope of attached on the surface of the liquid or debris.

After removed the damaged bearing

1 Inspect All parts of the damaged bearing appearance carefully and observe damage features (use a magnifying glass.All kinds of microscope scanning electron microscopy (sem) or perspective electron microscopy) control information on record find the main reason of bearing damage analyze to be covered in the subsequent phenomena start.Study the properties of the damaged belongs to fatigue abrasion corrosion or electric erosion examine the geometrical characteristics of the damaged belongs to overload partial load shock vibration burning or the material problem

2 Check the running working condition of the same model bearing observe whether there is the same damaged bearing exists weakness compared with the actual service life of the bearing According to the common bearing damage features to check if it belongs to bearing "innate" defects or problems,then to control them.

3 If necessary should do investigation records to the date of bearing purchase inventory antirust treatment and transport situation review bearing stored area inside the warehouse field such as temperature humidity range.Find out if due to inventory too long to produce corrosion or size changes or transportation micro motion abrasion and if the packing are in good condition.

4 According to the above program analysis judgment still can't find out the reason in conditions allow try to make other necessary try.Under similar conditions of the same model bearingthe necessary instrumentshould be equipped with for measuring record in detail.

5 In the case of important occasions bearing factory or bearing research institute can be invited to participate in analysis and research.
