Four major causes and solutions for premature failure of wood pellet machine bearings
Many customers have prematurely damaged the sawdust machine bearing after purchasing the wood pellet machine. At this time, it is considered that the quality of the bearing produced by the pellet machine manufacturer is not enough, and the indignation is looking for the manufacturer theory. In fact, most people don't know that the general bearing burns out, and many of them are not quality reasons, but the premature damage of the wood chip machine bearing caused by the improper operation of the customer during the operation. The following small series summarizes the following four reasons for your reference.
First, improper installation (about 16%)
1. Use brute force during installation. Directly hitting the bearing with a hammer will cause the greatest damage to the bearing; it is the main cause of deformation.
2, the installation is not in place, the installation is biased or not loaded to the bearing position, resulting in too small bearing clearance. The inner and outer rings are not in the same center of rotation, causing disagreement.
Recommendation: Select an appropriate or professional bearing installation tool, and use a special instrument to detect it after installation.
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 adding 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.
Recommendation: Choose the right lubricant or lubricant and use the correct lubrication method.
Third, pollution (about 14%)
Contamination can also lead to premature bearing damage, which means that dust, metal chips, etc. enter the bearing. The main reasons include: opening the bearing packaging too early before use, causing pollution; the working environment is not clean during installation, causing pollution; the working environment of the bearing is not clean, and the working medium is polluted.
Recommendation: It is best not to disassemble the bearing before use; keep the installation environment clean during installation, clean the bearing to be used; and strengthen the bearing seal.
Fourth, fatigue (about 34%)
Fatigue damage is a common way of damage to bearings. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to repair in time; improper maintenance; equipment aging.
Recommendation: Select the appropriate bearing type and replace the fatigue bearing regularly.
The above are the most common causes of early damage of imported bearings due to the wood chip machine; the reasons for the early damage of the bearing are various, the above is the main consideration, and sometimes it may be a comprehensive cause. If the bearing selection is correct, the installation method is in place, the lubrication method and lubricant selection are correct, and the bearing can work normally for a long time.
