Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. With the increasing demand for bearings, the premature damage of bearings, short life and other problems are plaguing every mechanical practitioner. Today, I want to share with you the methods and techniques to extend the service life of bearings. Welcome to share your experience.

Bearings with the same appearance under the same working conditions have very different actual lifespans. What causes this? The following points are summarized: 1. Improper installation (about 60%) 1. Excessive force during installation, among which hitting the bearing with a hammer is the most harmful to the bearing; it is also the main cause of deformation. 2. The installation is biased or not installed in the bearing position, resulting in too small bearing clearance. The inner and outer rings are not at the same rotation center, resulting in eccentricity. Suggestion: Choose appropriate or professional bearing installation tools, and use special instruments to detect after installation. 2. Pollution (about 15%) Pollution can also cause premature damage to the bearing. Pollution refers to the entry of sand, dust, metal chips, etc. into 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, the working medium is polluted, etc. 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.

3. Poor lubrication (about 15%) According to the survey, poor lubrication is one of the main causes of premature bearing damage. Including failure to add lubricants or lubricating oils in time; lubricants or lubricating oils are not added in place; improper selection of lubricants or lubricating oils; incorrect lubrication methods, etc. Suggestion: Choose the correct lubricant or lubricating oil and use the correct lubrication filling method. 4. Fatigue (about 10%) Fatigue damage is a common damage mode for bearings. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to repair in time; improper repair; aging of equipment, etc. Suggestion: Choose the appropriate bearing type and replace fatigue bearings regularly and in time.
