bearings and grease
Posted by Bob on June 7, 2006
I am taking a test and the question is: “Either over- or underlubrication can cause bearings to overheat.” True or False?
The contest is that of pumps of sewer treatment plants. I am a professional engineer, with the EPA of Atlanta, in the water program, and they have paid forty-five (45) Dollars for me to take this course, since I review reports from wastewater treatment plants, almost daily. In fact, I have examined more than 120 reports, since February 19 of this year.-
Well, anyway, any response would be appreciated.
Over lubrication can be as bad for bearings as under lubrication, however the type of failure can be quite different. With under lubrication, the consequences are obvious with debris, and over heating being major problems which will lead to extreme short life.
However with over lubrication problems such as cavitation and erosion can cause damage to bearing surfaces which can also be disastrous for bearings.
