Critical Electric Motor Lubricant Inspection |
|
When receiving electric motors that have been rebuilt, inspect the grease tube to the bearings to ensure that contamination is not present (metal shavings, dirt, etc.) and to verify that the grease path to the bearings is full of grease. If the grease path is empty, it could take two to three years before any grease reaches the bearing since regreasing amounts are typically very small (0.3 to 0.7 ounces per year). (Randy Riddell, mechanical reliability engineer, International Paper)
Editors Note: It is also a good idea to insure that the rebuild shop uses the same electric motor grease as the plant to avoid any possibility of incompatibility.

Clearly Reliable
Avoid costly grease cross contamination errors. If you cannot see what is in the grease gun it is not grease identification, but grease assumption. Take control, by upgrading obsolete equipment to this cost effective solution that offers 100% grease visual identification. Find out More

Operating Temperature and Grease |
|
From the "Lubricating Grease Guide"
Most mineral oil-based greases (of adequate dropping point) will operate successfully to about 250 degrees F (121 degrees C). A smaller number can handle 300 degrees F (149 degrees C). A few mineral oil-based greases can operate to about 350 degrees F (177 degrees C). Around this temperature, synthetic fluids are preferred or required. As service temperature rises, frequency of lubricant addition and relubrication must increase.

How to Implement an Operator-assisted Lubrication Program
With 43% of U.S. companies pursuing a form of lean manufacturing, operators are increasingly being asked to assume some or all of a plants maintenance activities. And while Toyota is living proof that operator involvement can and does work, there are a few simple rules that will help you avoid problems in the future.

Your 5 Senses Are Lubricant Monitoring Tools |
|
Don't underestimate the value of your own senses in condition monitoring. That's right, your eyes, ears and nose can be valuable tools, and unlike other lubricant monitoring instruments, require little training to be utilized effectively.
