For boat trailers manufacturers recommend replacing the grease which means removing repacking and reassembling each wheel on the trailer every 3000 to 4000 miles or annually even if you dont travel very far. The grease will then break down and harden blocking any future grease.
Grease guns can produce up to 15000 psi and when you over-grease a bearing housing the lip seals can rupture allowing contaminants such as water and dirt to access the bearing housing.
Can you over grease bearings. Grease guns can produce up to 15000 psi and when you overgrease a bearing housing the lip seals can rupture allowing contaminants such as water and dirt to gain access into the bearing housing. Keep in mind that lip seals usually fail around 500 psi. Read Lip Seals - A Practical Guide for more about this topic.
Over-greasing is a common problem and can cause over heating that leads to reduced bearing life. Remember that for every 10C 18F rise in temperature over 65C 150F will cut the service life of the bearing in half. So how much grease does a bearing need.

For boat trailers manufacturers recommend replacing the grease which means removing repacking and reassembling each wheel on the trailer every 3000 to 4000 miles or annually even if you dont travel very far.
This results in accelerated wear of the elements and complete component failure. Over greasing is also to blame for seal failure and damage. Because grease guns produce up to 15000 psi lip seals can rupture allowing contaminates to enter the bearing housing.
Chris Adsett says seal damage is another negative side effect of over-greasing. Grease guns can produce up to 15000 psi and when you over-grease a bearing housing the lip seals can rupture allowing contaminants such as water and dirt to access the bearing housing.

If the excess grease reaches the motor windings the windings will get insulated with grease causing inefficient performance overheating and bearing failure. In addition to damaging your bearings over-lubrication can also have a significant impact on your. How often should I grease bearing buddies.

Large bearings especially large electric motor bearings are often lubricated through supply pipes line extensions from a grease fitting. Hardened thickener rust and other solids can build up in these pipes over time. Over greasing also causes heat buildup in the bearing.
This occurs because there is nowhere for the heat to dissipate. A full bearing will hold a higher temperature than a properly filled one. Also if a bearing is hot to the touch it is not necessarily overheating and in need of more grease.
The heatalong with the internal churning of the bearingwill force the grease to the outside of the bearing. The grease will then break down and harden blocking any future grease. The practice of over-greasing bearings not only is a waste of grease but it can also drastically shorten bearing life.
