So when you begin to look into why the motor failed, start by looking at the bearings. ... Knowing why the bearing failed and taking steps that prevent it from happening again improves the machine’s lifetime performance. ... Inspect the grease and look for any contamination in the bearing.
Identifying problems with lubricants can often be a difficult task. Even with mineral oils and synthetics fluids where oil analysis is widespread and commonly used, the underlying cause of a problem may not be obvious. When comparing greases, the picture gets even cloudier and more difficult. Most greases have minimal characteristics that can be used to compare one to another.

Condition-Based Monitoring and Acoustic Lubrication: ... But here’s why that application should be utilized. ... after one half stroke of the grease gun? You should pause 10 seconds and if the dB reading does not return to where it was prior to inflection, you should stop the lubrication procedure. Do not continue greasing.
But, if you turn the check valve around, it is impossible to blow any air through it. The same thing happens inside the compressor or compressed air system. Once the compressed air passes the check valve, there is no way it can go back again. Why it’s there. There are so many reasons why air compressor check valves are used on air compressors.

7 Best Practices for Bearing Inspection to Optimize Performance Cutting and inspecting every bearing in motors that come in for repair, especially motors operated on variable frequency drives, will often provide vital information to make the best repair recommendation and improve performance.
Things break. No matter what you do, there is always a chance that products will fail. The same holds true for bearings, but that doesn’t mean that you can’t prevent many of the issues that result in costly downtime.. This article is a guide to the major factors that can lead to bearing failure as well as how you can prevent the issues from happening.
Why You Should Inspect Bearing Grease Discharge There are three opportunities to inspect the state of in-service grease. One is by disassembly (such as by removing the bearing cap), the second is by sampling the grease using a probe (ASTM D7718), and the third is by examining the purge discharge.

Water pump bearings should be greased with about 2 oz of grease every 250 hours of service. Most water pumps should only be greased by hand and it should be noted that over greasing can damage bearings as well as no grease. High pressure grease guns can blow out grease seals in the pump causing grease loss and bearing failure.
By now it is widely understood that once the resulting shaft voltages overcome the dielectric properties of bearing grease, they discharge along the path of least resistance — typically through the bearings (Figure 1). ... inspect the race walls for electrical pitting/frosting/fluting. ...
