Bearing Lubrication


The age old question of grease versus oil when lubricating bearings.

At NASH Certified Service Centers, we see many pumps come through our doors with bearing failure. The question always asked is: why did it happen and what can be done to prevent future failures? Most bearing failures are not caused by a bearing manufacturer defect. The most common reasons for bearing problems are a lack of lubrication or the use of contaminated lubrication - and not the type of lubrication.
