Four major causes and solutions of premature failure of the bearings of a sawdust granulator

1、 Improper installation (approximately 16%)
1. Using brute force during installation and directly striking the bearing with a hammer can cause great damage to the bearing; Is the main cause of deformation.
2. Inadequate installation, installation deviation or not installed in the bearing position, resulting in too small bearing clearance. The inner and outer rings are not at the same center of rotation, resulting in misalignment.
Recommendation: Select appropriate or professional bearing installation tools, and use special instruments to inspect after installation.
2、 Poor lubrication (approximately 50%)
According to investigations, poor lubrication is one of the main reasons for premature bearing failure. The main reasons include: not timely filling lubricant or lubricating oil; Lubricant or lubricating oil is not filled in place; Improper selection of lubricants or lubricants; Incorrect lubrication method, etc.
Recommendation: Select the correct lubricant or oil and use the correct lubrication method.
3、 Pollution (approximately 14%)
Pollution can also lead to premature bearing damage, which refers to the entry of sand, dust, metal chips, etc. into the interior of the bearing. The main reasons include: premature opening of the bearing packaging before use, resulting in pollution; The working environment is not clean during installation, resulting in pollution; The working environment of the bearing is not clean, and the working medium is polluted.
Suggestion: It is best not to unpack the bearings before use; During installation, keep the installation environment clean and clean the bearings to be used; Strengthen the sealing device of the bearing.
4、 Fatigue (approximately 34%)
Fatigue failure is a common failure mode of bearings. The common causes of fatigue damage may be: long-term overload operation of bearings; Failure to repair in a timely manner; Improper maintenance; Equipment aging, etc.
Recommendation: Select an appropriate bearing type and regularly and timely replace fatigue bearings.
