In one minute, we will show you the common faults and solutions of SG series bearing!
SG series bearing, especially the guide roller with "Gothic" arc groove, is widely used in industrial automation, mechanical equipment and other fields. But like other types of bearings, SG series bearing will also have some common faults during use. This article will analyze the causes, phenomena and corresponding solutions of these faults in detail.
Common causes of SG series bearing failure:
1. Improper installation:
The clearance between the bearing and the guide rail is too large or too small, and the installation angle is inaccurate, which will cause early damage to the bearing.
2. Poor lubrication:
Improper selection of grease, insufficient or excessive grease, grease contamination, etc., will cause SG series bearing friction to increase, generate high temperature, and accelerate wear.
3. Overload operation:
The load borne by the bearing exceeds its rated load, which will cause plastic deformation and even fracture of components such as raceways and rollers.
4. Vibration and shock:
The vibration and shock generated during the operation of the equipment will accelerate the wear of the bearing and shorten its service life.
5. Impurity intrusion:
External dust, metal chips and other impurities enter the bearing, which will scratch the rolling element and raceway and accelerate the wear of the bearing.
6. Corrosion:
Corrosive media in the working environment will corrode the metal surface of the bearing, resulting in a decrease in bearing performance.
Common fault phenomena and solutions for SG series bearing:
Vibration noise:
Cause: There are debris in the SG series bearing, poor lubrication, bearing damage, etc.
Solution: Clean the bearing, replace the grease, check whether the bearing is damaged, and replace the bearing if necessary.
Unsmooth movement:
Cause: The clearance between the bearing and the guide rail is too large or too small, the bearing is damaged, etc.
Solution: Adjust the clearance between the bearing and the guide rail, check whether the bearing is damaged, and replace the bearing if necessary.
Shortened life:
Cause: The combined effect of multiple factors, such as overload, poor lubrication, impurity intrusion, etc.
Solution: Comprehensively analyze the causes of the failure and eliminate them one by one.
