The life of air compressor bearings and the causes of damage

If the air compressor loses one bearing or does not pay attention to the correct use of the bearing, the air compressor will not be able to operate normally, and it will greatly shorten the service life of the bearing, which will bring us unnecessary losses. So below, the editor of okmarts.com will analyze the life of air compressor bearings and the causes of damage.

　　 1. Improper installation (about 16%)

　　 1. Using brute force during installation, directly hitting the bearing with a hammer will damage the bearing the most, which is the main cause of deformation.

　　 2. The installation is not in place, the installation is deviation or the bearing is not installed, resulting in too small bearing clearance. The inner and outer rings are not at the same center of rotation, resulting in misalignment.

　　Recommendation: Choose appropriate or professional bearing installation tools, and use special equipment to test after installation.

　　 2. Poor lubrication (about 50%)

　　According to the investigation, poor lubrication is one of the main causes of premature bearing damage. The main reasons include: the special lubricant or lubricating oil for the air compressor was not filled in time; the lubricant or lubricating oil was not filled in place; the lubricant or lubricating oil was not properly selected; the lubrication method was incorrect and so on.

　　 Suggestion: Choose the correct lubricant or lubricating oil and use the correct lubrication filling method.

　　 3. Pollution (about 14%)

　　 Pollution can also cause premature bearing damage. Pollution means that sand, dust, metal chips, etc. enter the inside of the bearing. The main reasons include: opening the bearing package 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.

　　 Suggestion: It is best not to unpack the bearing before use; keep the installation environment clean during installation, clean the bearing to be used; strengthen the sealing device of the bearing.

　　 Fourth, fatigue (about 34%)

　　 Fatigue damage is a common damage method for bearings. Common causes of fatigue damage may be: long-term overload operation of air compressor bearings; failure to repair in time; improper maintenance; equipment aging.

　　 Suggestion: Choose the appropriate bearing type and replace the fatigue bearing regularly and in time.

　　 The above is the most common cause of bearing damage and greatly shortened bearing life! As long as we use it correctly and maintain it well in our daily life, then the air compressor bearings will work well for us!
