Analysis of damage causes and countermeasures of aligning roller bearings

One, improper installation

1. The main reason for the deformation is the use of brute force in the installation process and the direct impact of hammer on the bearing (class 35 centering roller bearing), which causes the maximum damage to the bearing.

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

Recommend: choose appropriate or professional bearing installation tools, after the installation of the use of special instruments for testing.

Two. Bad lubrication

According to the investigation, poor lubrication is one of the main causes of premature bearing damage.The main reasons include: lubricating oil or lubricating oil is not filled in time, lubricating oil or lubricating oil is not filled, lubricating oil or lubricating oil is not the correct choice, lubrication mode is not correct, etc.

Recommendation: select the right lubricant or lube and use the correct lubrication filling method.

3. Fatigue

Fatigue damage is a common way of bearing damage.The common causes of fatigue damage may be: bearing overload for a long time;Failure to maintain in time;Improper maintenance;Equipment aging, etc.

Suggestion: select proper bearing type and replace fatigue bearing regularly.

Pollution of four.

Contamination can also cause premature bearing damage, when dust and metal particles enter the bearing.The main causes include: pollution caused by opening the bearing packing too early before use;The working environment is not clean, resulting in pollution;Bearing working environment is not clean, working medium pollution, etc.
