Bearing Buddy installed diagram

Bearing Buddy Operation

Replace your existing grease cap with a Bearing Buddy to ensure a safe, easy way to monitor and control the level of grease in your axle hub. To adjust the amount of grease in the hub, use a grease gun to add more through the appropriate fitting. Adding grease moves the Bearing Buddy spring-loaded piston outward 1/8".

The O-ring inside the barrel of the Bearing Buddy maintains a seal from the outside. The interior of the Bearing Buddy is pressurized, preventing water from entering the barrel and diluting the grease.

An automatic pressure-relief feature is built into the Bearing Buddy. When the device is full, grease will seep around the edges of the piston and into the barrel. This prevents overfilling that can damage the inner seal.

You can manually check the grease level in your Bearing Buddy by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled.

Specs matched great. Having good specs and descriptions along with details picture when appropriate, make all the difference. Will be ordering for my other trailer soon.


Very nice bearing covers, great price and customer support. Had issues fitting on to hub but shaved down contact surface just a bit and bearing cover fitted on snug. Would definitely purchase again.


Works as it should, quality product and gives me peace of mind knowing the bearings on my horse trailer are lubricated.


One of the bearings would not go on. I had to Chuck it in the lathe and true it to go on.

You mentioned that one of the bearings was difficult to put in however I was not sure what you had to do to install it. Could you explain in more detail?


Everything they said about shipping was true, it worked out great, thx


Fast delivery thanks


These bearings Caps look great.
looked forward since I received my order. Unfortunatly I only installed these Bearing Buddy protector grease caps last week.
I tried last spring before to launch the boat, but the diameter of the caps was a little to large for my hubs. I brought them to a machine shop with one of the old dust caps.


Installed grease caps on older equipment trailer that was purchased used. After Repacked bearings and installed new wheel seals. grease caps give me peace of mind that there will be no non lubricated wheel bearings.


Excellent service and knowledge of the part.


Great product


These are very simple and convenient. When installing them I used a plastic hammer to get them started. I then used a 1 to 2 foot piece of 2x4 with one end on the buddy and hit the other end with a heavy hammer. Much easier than using the side of the 2x4 and this sent it straight in. Smack the 2x4, turn in a quarter turn, hit if again. I had a super tight fit on all 4 axles, so expect it to be snug.


Product installed very simply. Hardest part was removing the old hub caps. Installed 4 bearing buddies and filled with grease in less than 30 minutes. Received the product earlier than expected from etrailer. Great deal!


Great deal all round, there was a availability issue with my online order, but they called me and we resolved the issue by swapping for better product that was available, delivery was fast and product fitted exactly as described very easy. I would and will be ordering from "etrailer" again, just have to find something I need!!!! Soon I hope.


Works great! Well worth the piece of mind pulling my 5th wheel!


Fit well and they keep the water out of my boat trailer bearings. Wouldn't have a boat trailer without them.


Easy to use website products arrived qu ickly


These are awesome! They look good and keep the trailer bearings well lubricated.


Bearing buddies rock. Wouldn't haul a trailer without them. And what better place to buy them than etrailer!


Fit was extremely tight. Would have been a better fit if .002 - .003 smaller diameter. I hope I am not the one that has to remove them :), because I had to force them in.


Paid for two day and it took three day. Supposed to refund me $X.XX


I think these bearing buddies are awsome. Stainless is the was to go


The name alone stands out as a great product which is what Bearing Buddy has become.


Bearing buddies came on time and fit perfectly. Great transaction, thank you!


Quick shipping

  • Bearing Buddies for a 6,000 Pound Dexter Axle with 8 Lug Hub
    Check the outer bearing and race numbers stamped into the metal of the bearing and race in the hub. Most 6,000 pound 8 lug wheels we carry use outer bearing # 14125A if it is an 8 on 6-1/2 bolt pattern. If it is an 8 on 8 bolt pattern, it may use # 506849 outer bearing. If you have the 14125A outer bearing, you can use Bearing Buddy Bearing Protectors, # BB2717SS, or # BB2717.

  • Bearing Buddy That Fits 2.7 Inch Hub Bore
    We do have a Bearing Buddy which fits a similar dimension as the 2-3/4" you referenced but I do recommend using a digital caliper and measuring your hub bore size to the thousandths of an inch to ensure you get the correct fit. For a 2-3/4" hub bore the closest fit we have are Bearing Buddies that fit a 2.717" hub bore, the Bearing Buddy Bearing Protectors - Model 2717SS - Stainless Steel # BB2717SS and the Bearing Buddy Bearing Protectors - Model 2717 - Chrome Plated # BB2717.

  • Should Bearing Buddy System Replace Sure Lube Hub Setup on Trailer
    By Sure Lube you mean like an EZ Lube setup that has zerk fittings on the ends of the spindles to grease through the middle of the hub? That's what I was able to find when Googling your setup. If so, you can install a Bearing Buddy over this style of hub but it's typically better to stick with the EZ Lube setup as it applies grease in a way that's easier to reach the bearings. If you can get me the diameter of your hub where the grease cap fits I can get you a cap with a removable center...

  • Precision Digital Caliper to Measure Hub Bore to Select Correct Bearing Buddy Bearing Protector
    Bearing Buddy protectors are made in lots of sizes, many of which are very close to one another in their diameter. It is really necessary to use a more precise measuring device on the hub's bore unless you know the part number of the one that was lost. You might check the remaining one for any identification. There are two sizes that are close to your 2-9/16-inch dimension, 2.562-inches and 2.717-inches. Bearing Buddy parts that fit hub bore diameter 2.562-inches are either part # BB2562SS...

So if you do that and your hub bore measures 2.717 inches, you can use the Bearing Buddy Bearing...

  • Which Bearing Buddy Will Fit a 2 5/8 Hub Bore
    The hub bore of 2 5/8, or 2.625, is kind of an odd size. It puts you in between the Bearing Buddy # BB2562SS, which fits a 2.562 inch hub bore, and the Bearing Buddy # BB2717SS, which fits a 2.717 inch hub bore. That being said. the # BB2562SS is not a common size and is used mostly for agricultural applications. The # BB2717SS is going to be your best bet, but may require a little sanding of either the part of the hub to get everything seated properly.

  • Which Bearing Buddy Fits Hubs of 2019 Keystone Sprinter 3531FWDEN
    Since we know your 2019 Keystone Sprinter 3531 5th wheel has 7k axles like what the Dexter hub part # 42866UC3-EZ fits we know that the correct Bearing Buddy is the part # BB2717 that you referenced. Or if you wanted the stainless steel version that won't corrode you'd want the part # BB2717SS. It's pretty easy to over-fill hubs with grease using Bearing Buddies though so be careful not to put so much grease in the hub that it blows out the seal on the backside of the hub.

  • Do You Have a Grease Cap/Dust Seal Which Fits a 2.6875" Hub Bore?
    The Bearing Buddy Protectors 2.562" # BB2562SS and 2.717" # BB2717SS are the closest sizes we have to your 2.6875. While these are not an exact fit you may be able to have some bushings machined or machine down the larger size to fit these options. We do not have a standard grease cap/dust seal close to the measurement you need.

  • Needing to Find the Correct Bearing Buddies on 7,000 Lbs Trailer Axles
    When finding which set of Bearing Buddies will work on your trailer axles, you will need to find a couple of pieces of information. First, know the outer bearing number would be the best piece of info that you can use to figure out which Bearing Buddies set will fit your axles. For example, if your outer bearing is # 14125A, then # BB2717SS would be the correct Bearing Buddies Set. If you can measure the outer diameter of the part, then you can also look-up the Bearing Buddies Set...

  • Is There a Replacement for the TDE Turbo Lube 48395 Oil Cap
    I might have some options for you but I wasn't able to reference the TDE Turbo Lube 48395 Oil Cap. Therefore, in order to find a replacement for this you'll need to measure the outer diameter of the threaded portion on the oil cap. The Oil Cap, Plug and O-Ring part # RG04-230 for example fits a 2-7/8" hub bore. There is also the option of switching to grease and using a cap like the Bearing Buddy Bearing Protectors part # BB2717SS which fit a 2.717" hub bore. I have attached other sizes...
