Perhaps the most difficult task is determining if and when a bearing needs to be serviced. This determination requires much more than a quick visual inspection. Below are a few signs to look for when inspecting bearings that may need to be repaired:

• The bearing is nearing suggested life expectancy.
• The bearing has exceeded an operating temperature of 200° F (93° C).
• The bearing has been exposed to excessive vibration.
• The bearing experienced a sudden drop or gain in lubrication.

Paying attention to these details during regular maintenance checks can help you determine if a bearing needs maintenance before it causes unnecessary downtime and expense. Careful observation is the first step to creating a program that monitors your bearings and surround operations.
