Accurately judging the fault problem of the ball bearing is of great significance. In many cases, because the failure can not be accurately judged in time, the probability of failure and maintenance cost are increased.
Most ball bearing failures, such as flaking, pitting, flaking, deflection, creep, corrosion, rust, and abnormal wear patterns, are caused by a relatively small set of causes.
These causes are usually interrelated and can be corrected at the same time.
The main reasons for the failure of ball bearings include installation, installation, working stress, environmental impact and bearing selection.
Proper lubrication is essential to improve the service life of ball bearings. It helps to cover the rolling and sliding surfaces with a thin film of oil to avoid direct metal-to-metal contact.
This helps reduce wear and friction and improve the life of ball bearings.
Grease is used to lubricate the surface because it is easy to handle and helps simplify the sealing system.
Oil is a good lubricant for high temperature or high speed operation.
Lubricating oil failure may be caused by the following reasons: using the wrong lubricating oil, using too much grease or lubricating oil, using too little grease or lubricating oil, mixing grease and lubricating oil or using contaminated Grease/lubricating oil.
The installation and installation process is another area that can cause bearing failure.
During installation and installation, appropriate tools must be used.
In order to prolong the service life of ball bearings, the misalignment and shaft deflection should be minimized.
Operating pressure is another cause of bearing failure.
In general, factors in large applications can be changed at any time. If the load is too high, it may cause overload and early stress.
Similarly, if the load is too low, skidding may occur. Abnormal noise and elevated temperatures are the first signs of such problems.
