Reason 1: the clearance is too large, countermeasures: research cooperation and bearing clearance, modify the pre load.
Reason 2: foreign intrusion, countermeasures: a study of replacement of bearings, wash the parts, improve sealing device, the use of clean lubricant.
Reason 3: spherical injury, peeling, countermeasures: replacement of bearings.
Abnormal temperature rise
Reason 1: excessive lubricant, miniature ball bearings countermeasures: reducing lubricant grease, proper use, select the hard.
2 reasons: lack of lubricant or not suitable, countermeasures: add lubricant, select the appropriate lubricant.
Reason 3: abnormal load, countermeasures: modify the coordination, clearance of bearing pre load, adjust, modify the shoulder position of the shell.
Reason 4: poor installation, countermeasures: improve machining precision, and shell axis installation accuracy, installation method.
Reason 5: surface slewing bearing creep, seal friction is too large, countermeasures: replacement of bearings, study, modify the shaft and housing, changes the sealing form.
Vibration (axial runout)
Reasons: (1 Steel Carburized) surface deformation, countermeasures: Note bearing replacement operation.
Reason 2: peel, countermeasures: replacement of bearings.
Reason 3: poor installation, reali slim bearings countermeasures: axis, shell shoulder pad angle, side angle.
Reason 4: foreign intrusion, countermeasures: replacement of bearings, cleaning parts, improved sealing device.
Lubricant leakage is overmuch, discoloration
