How to calculate grease quantity and frequency for bearings?
The formula is as follows: Re-lubrication Amount of Grease (g) = 0.005 * Bearing Outside Diameter (mm) * Total Bearing Width (mm). If the speed and load are known for the bearing; only then can a frequency be determined, otherwise it is trial-and-error. Unfortunately an error in lubrication means a machine is down.

How much Greese should be in a bearing?
Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.
How often should I add grease to Bearing Buddy?
They said the best thing to do is have the bearings packed once a year. Once packed and with a good seal, there is no need to add more grease. Grease doesn't get consumed by bearings. You shouldn't lose grease if your seal is fine and your bearing buddy isn't squirting grease out the front.

Can you over grease trailer bearings?
Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.

How long does wheel bearing grease last?
Closed Bearings “Lubricant deteriorates over time as a result of aging, condensation, and separation of the oil and thickener. For closed bearings – sealed or shielded – that contain the standard domestic grease (GJN), and that are still in their original, unbroken packaging, the recommended shelf life is five years.

What are bearing buddies?
bearing buddies are the best invention since sliced bread..... they offer no advantage whatsoever for a trailer that is NOT dunked but they will definitely prevent water intrusion on a boat trailer so long as you keep them "charged" as the above poster stated.
Do bearing buddies keep pressure?
The bearing buddies keep pressure inside the hubs, so when they are submerged, the cooling hubs and bearings don't suck water in. Too much grease in the bearing buddies can blow out the rear seal defeating the whols purpose. Bearing buddies do not eliminate the need for regular maintenance and inspections. L.
How often should I grease bearings?
How often should I grease my bearings, and how much grease do they need? 1 FOR STARTERS, note that most sealed bearings come pre-greased from the factory with a 25%-35% grease fill. This is all the grease the bearings will ever need, because the relubrication interval (explained below) is longer than the expected life of the bearing. 2 DON’T JUST GUESS. It can be tempting to give the bearings a pump of grease each day, or to pump until grease comes out from under the seals. However, this effectively destroys the seal’s ability to keep contaminants out of the grease; and too much grease “churns” inside the bearing, generating resistance and leading to rapid heat build-up. 3 FREQUENCY: The accompanying chart shows approximate relubrication intervals. Start at the bottom by choosing your speed; follow the line straight up until you meet the curve that matches your bearing O.D., then go straight left to see the relubrication interval for your bearing type. 4 AMOUNT: To find ounces, [ (OD in inches) x (width in inches) x 0.114]. To find grams, [ (OD in mm) x (width in mm) x 0.005].
Can you pump grease out of bearings?

However, this effectively destroys the seal’s ability to keep contaminants out of the grease; and too much grease “churns” inside the bearing, generating resistance and leading to rapid heat build-up.
Where to put grease on bearings?
In addition to packing the bearings in the traditional manner, it's best to get as much grease as possible inside the hub cavity between the bearings and then, while the Bearing Buddy® is off, fill it with grease as well from the backside.
How does bearing buddy work?
How Genuine Bearing Buddy® Works. The axle hub is filled with grease until the grease forces the Bearing Buddy® piston outward about 1/8 inch. Because the piston is spring loaded, the piston exerts a slight (3 PSI) pressure against the grease, which maintains a slight pressure between the inside of the hub and the outside environment.
Where is grease added to a piston?
Grease can be added to the hub through an easily accessible grease fitting located in the center of the piston. Lubricant level (and pressure) can be checked quickly by pressing on the edge of the moveable piston. If you can rock or move the piston, the hub is properly filled.
Why can't water enter a bearing hub?
When the hub is submerged, water cannot enter the hub because of this pressure. An automatic pressure relief feature prevents over-filling and over pressurization. See Bearing Buddy diagram: Without this feature, the inner seal will be damaged.

What happens when you put too much grease in a bearing?
Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease , pushing it out of the way, resulting in energy loss and rising temperatures. This leads to rapid oxidation (chemical degradation) of the grease as well as an accelerated rate of oil bleed, which is a separation of the oil from the thickener.
What is a bearing buddy?
The bearing buddies are created to protect and prolong the life span of the bearings by keeping dirt and water out of the hub. The fill-up valve on the bearing buddy will also prevent overfilling and rear seal damage with an automatic pressure relief feature.
What happens when oil bleeds into grease?
The heat that has been generated over time along with the oil bleed eventually will cook the grease thickener into a hard, crusty build-up that can impair proper lubrication and even block new grease from reaching the core of the bearing. This can result in accelerated wear of the rolling elements and then component failure.
Why are boat trailer bearings corroding?
Unlike regular trailers, The #1 issue with boat trailers is that the bearings get immersed in water and can, therefore, easily become contaminated and begin corroding because of the water intrusion without this fact being readily noticeable.
How to put grease in rollers?

What is bearing bb2441?
The Bearing Buddy Protectors have a spring loaded seal that keeps the moisture and debris out of the bearings. This pressurized grease will maintain bearing function as long as the seal on the hub stays functional. If this seal is broken, I recommend inspecting and repacking good bearings when you replace the seal. As you maintain the grease in the Bearing Buddy, it continues to fill the bore, so your bearings and spindle stay properly lubricated for proper function.
