Thrust ball bearings are likely to be damaged early
When we use the thrust ball bearings, in many cases the thrust ball bearings will occur early damage symptoms, many people will ask: "Why use the bearings will occur early damage to the symptoms of the bearing early damage how?" These problems, Thrust ball bearings Lead to bearing damage in advance for many reasons, such as improper installation, poor lubrication, pollution and fatigue caused by the transition, the following explain about the early damage to the thrust ball bearing the main reasons there are four.
First, improper installation (about 16%)
1, the installation of brute force, with a hammer directly hit the bearing bearing the largest damage; is the main cause of deformation.
2, the installation is not in place, installed with no deviation or installed to the thrust ball bearing position, resulting in bearing clearance is too small. Inner and outer ring is not in the same rotation center, resulting in different heart.
Recommendation: Thrust ball bearings Select the appropriate or professional bearing installation tool, the installation is complete with a special instrument to detect.
Second, poor lubrication (about 50%)
According to the survey, poor lubrication is one of the main causes of premature bearing damage. The main reasons include: not timely filling lubricants or lubricants; lubricants or lubricants are not filled in place; improper selection of lubricants or lubricants; lubrication is not correct and so on.
Recommendation: Select the correct lubricant or lubricant, using the correct lubrication filling method.
Third, pollution (about 14%)
Pollution will lead to premature damage to the thrust ball bearings, pollution is dust, metal chips into the bearing inside. The main reasons include: open before the use of bearing packaging, causing pollution; installation of the working environment is not clean, resulting in pollution; bearing the working environment is not clean, working media pollution.
Recommendation: Before use, Thrust ball bearings it is best not to open the bearing packaging; installation to keep the installation environment clean, to use the bearings to be cleaned; enhanced thrust ball bearing seal.
Fourth, fatigue (about 34%)
Fatigue damage is a common damage to the bearing. Common causes of fatigue damage may be: long-term overload operation of the bearing; not timely maintenance; improper maintenance; equipment bearing exposed to pollutants or moisture environment. If the work is interrupted, should be oil paper plastic film or similar material over the machine. Thrust ball bearings If you do not have to disassemble and may perform the inspection of the case of cleaning unmasked bearings, the coating should be coated with a brush with oil solvent cleaning, and then a piece of lint-free fabric dry or compressed air to dry, and then use The
