Radial runout of the bearing outer ring of the complete rolling mill Kea the difference between the large and small radial spacing between the outer diameter and the relative inner ring when the outer ring is at different angular positions.
The rolling inlet bearing bodies at the angular position of the above points or at the left and near sides shall be in contact with the inner surface of the inner race, outer race raceway or inner race back flange (tapered roller bearing), that is, FAG bearing parts are in a normal relative position.The assembly quality of fag rolling mill bearing determines the cause of damage.
The assembly quality of fag rQolling mill bearing determines the cause of damage
The runout of the inner ring end of the complete set of bearings facing the raceway, SIA when the inner ring is at different angular positions, the difference between the large and small axial spacing between the reference end face of the inner ring and a fixed point related to the outer ring at the radial spacing from the inner ring axis is equal to half of the contact diameter of the inner ring raceway.
The inner and outer raceways shall be in contact with all rolling elements.The assembly quality of fag rolling mill bearing determines the cause of damage.
Runout of the bearing outer ring end of the complete rolling mill facing the raceway when the sea outer ring is at different angular positions, the difference between the large and small axial spacing between the reference end face of the outer ring and a fixed point related to the inner ring at the radial interval from the outer ring axis is equal to half of the contact diameter of the outer ring raceway.
The inner and outer raceways shall be in contact with all rolling elements.The assembly quality of fag rolling mill bearing determines the cause of damage
When installing, use brute force and directly knock the bearing with a hammer, which will cause great damage to the bearing; Is the main cause of deformation.The assembly quality of fag rolling mill bearing determines the cause of damage
Bearing clearance is too small or fag is not installed in place, resulting in small clearance. The inner and outer rings are not in the same rotation center, resulting in non concentricity.The assembly quality of fag rQolling mill bearing determines the cause of damage
The assembly quality of fag rQolling mill bearing determines the cause of damage
Suggestion: select appropriate or professional bearing installation tools, and use special instruments to test after installation.The assembly quality of fag rQolling mill bearing determines the cause of damage
According to the investigation, poor lubrication is one of the main reasons for premature bearing damage. The main reasons include: failure to fill lubricant or lubricating oil in time;
Lubricant or lubricating oil is not filled in place; Improper selection of lubricant or lubricating oil; Incorrect lubrication method, etc.The assembly quality of fag rolling mill bearing determines the cause of damage
Suggestion: select the correct lubricant or lubricating oil and use the correct lubrication filling method.
Pollution will also lead to premature bearing damage. Pollution refers to the entry of dust and metal chips into the bearing of the rolling mill. The main reasons include: opening the bearing package prematurely before use, resulting in pollution;
The working environment is not clean during installation, resulting in pollution; The working environment of the bearing is not clean and the working medium is polluted.The assembly quality of fag rolling mill bearing determines the cause of damage
Suggestion: do not unpack the bearing before use; During installation, keep the installation environment clean and clean the bearings to be used; Strengthen the sealing device of fag bearing.The assembly quality of fag rolling mill bearing determines the cause of damage
Fatigue failure is a common way of bearing damage. The common causes of fatigue failure may be: long-term overload operation of bearing; Failure to repair in time; Improper maintenance; Equipment aging, etc.The assembly quality of fag rolling mill bearing determines the cause of damage
Radial runout of the bearing inner ring of the complete rolling mill Kia the difference between the large and small radial spacing between the outer surface of the inner hole and a fixed point relative to the outer ring when the inner ring is at different angular positions.
The rolling elements at the angular position of the above points or at the left and near sides shall be in contact with the inner surface of the inner race, outer race raceway or inner race back flange (fag bearing), that is, the bearing parts are in the normal relative position.The assembly quality of fag rolling mill bearing determines the cause of damage
