bearing

With the development of high technology, traditional ball bearings have been forgotten, but mechanical parts still need ball bearings to drive. Bearings are important components in household appliances, industrial equipment, automotive generators and fans. Today we will take a look at some common bearing problems.

(1) "Is the failure a bearing problem?"

Bearings from many years ago can fail due to fatigue caused by defects in materials, design or manufacturing processes. Today, the vast majority of bearing failures are due to external causes, so the reliability of bearings no longer depends on the bearing manufacturer, the end owner, that is, you now have the opportunity to take improvement action in a proactive manner.

(2) "How long should the bearing be used?"

The answer to the question is crucial, it will tell us whether the bearing failure is natural life, or premature failure? If the bearing reaches the service life recommended by the OEM, we only need to replace it in the most professional manner. However, if the bearing does not reach the recommended service life, it is premature failure, we must carry out root cause failure analysis, find the root cause, and determine and implement the corresponding corrective measures to avoid the same failure again!

(3) "3 steps to improve bearing reliability."

Correct selection of bearings: The application must be analyzed in detail to select the best bearings and their characteristics. The correct bearing must not only consider the bearing type and size required by the load, speed, but also consider other designs required by the working conditions (clearance, accuracy, lubrication, etc.). Proper installation: Use the correct installation methods and tools to avoid damaging the bearings and other parts of the machine. Correct lubrication: Select the best lubricant for each application and lubricate correctly.

(4) "Must the lubrication be as good as the bearing?"

Once the lubrication fails, any bearing will fail, because no bearing can withstand metal-to-metal contact! Statistics show that 55% or more of premature bearing failure is caused by improper lubrication.
