Now that you know the consequences of over-lubrication, it’s your responsibility to ensure it doesn’t happen in machines. When it comes to preventing over-lubrication, it is key to have a proper training system and lubrication management program (LMP) in place that keeps everyone in line. Start by identifying the best grease to use with equipment, then train workers on all the proper re-greasing techniques and processes.

Most people understand why a piece of equipment breaks down from being under-lubricated, but over-lubrication is a little harder to grasp. it’s certainly an issue that needs to be taken seriously, and is one that happens a lot more often than we realize.

Over-lubricating bearings will cause the rollers or balls to slide along the raceways, rather than turning. As they push along, they also push the grease out of the way, resulting in a low to no lubrication scenario. This grease churn and accelerated rate of oil bleed will cause your component temperatures to rise, which in turn will cause the grease to harden and hinder lubrication even more—causing oxidation and resulting in bearing failure.

Yeah - this is overpacking really. Old rule of thumb was pack to between a third and a half. Also too "efficient" a friction modifier can and does lead to bearing skid in rolling element bearings with the effect that the rolling element doesn't roll and spends too long on one plane in the load zone plus smears the bearing. People think all low friction is good but some components in complex machines need a bit of friction or they suffer badly.

Well I never! Information is King , how we interpret and deliver it is another. Interesting topic for all who use machinery and also for those of us who advise the end users

Point no 1 about the balls or rollers sliding if over greased rather than rotate is absolutely bogus. The author has apparently never seen the load diagram of a functioning bearing, nor has he any knowledge of the way the lubrication wedge is formed. The other points, yes, there may be consequences for over greasing.

What happens if over-lubricate bearings, it’s important that understand the main causes of over-lubrication so we can avoid them in the future.

In addition to damaging bearings, over-lubrication can also have a significant impact on equipment’s seals. Excess grease has a tendency to find its way between lip seals, causing them to rupture and allowing contaminants like water and dirt to leak into the bearing housing. This can force you to completely flush system.

You know what they say: everything’s better in moderation—including lubrication for your bearings. While you might think there’s no such thing as over-lubricating, using too much grease can lead to serious problems with machines, including grease churn, overheating, damage to the electric motor, and seal damage. over-lubrication is one thing that’s easy to avoid, as long as you know what to do and take the time to do things right.

We also need to determine the proper re-greasing frequency and grease amount — We can use vibration or sound analysis to determine the ideal grease level.

In order to prevent over-lubrication, We have to be extra cautious and follow the proper replacement schedule and techniques when re-greasing bearings. Most of these greasing mistakes are easily prevented with the proper training and knowledge, but when we find cases of over-lubrication, these tend to be the most common causes:

In instances where bearings are in an electric motor, over-lubricating those bearings can cause serious damage. If the excess grease reaches the motor windings, the windings will get insulated with grease, causing inefficient performance, overheating, and bearing failure.
