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.

This is a very easy install for such great protection. If you want to keep those bearings greased this is the way to go! Once again, the best help finding the perfect product!


Excellent product. Have used them on 3 trailers. Every time I buy a used trailer, I completely rebuild the hubs, bearings and brakes.

I don’t trust other people to keep boat axels, up to my standards. We travel long distances with our boat trailers.

Never had a failure.

Thank You etrailer!


The old bearing caps left a lot to be desired. These did the job perfectly. The trailer traveled coast to coast without an issue.


I have not been on a trip since installing the ss bearing buddies on my camper, however they were very simple to install and I look forward to the ease of greasing my hub bearings now. I had to modify my hub covers so I can access the bearing buddies to grease them.

Sorry the pictures would not upload to this site.


I've used Bearing Buddys properly for 13 years Four Boat trailers, Two Motorcycle trailers and a 21' camper. I have not had a case of water intrusion or bearing failure.


Very handy gadget. Stayed in place. Even the rubber covers have stayed on.
Easy to get on & off when needed.


They do what they say they do, kind of a pain to get hammered onto the disc, but thats a good thing because I know they are sealed really well


I installed these stainless bearing buddies in 2010. It's now 8 years later and they still work and look like new. Other than forcing in a few squirts of grease at the end of each season I've done nothing else and my hubs still spin like new despite getting constantly dunked into salt water.


Got my bearing buddies installed and I'm ready to go!
Thanks etrailer!


etrailer was great. I ordered the wrong bearing buddies, and I called to initiate the return, and everything went super smooth. Abigail help me with the return, and to order the correct ones for my 5th wheel trailer. I would recommend to everyone I know. thanks again. The bearing buddies fit great and work great. I had a trailer with bearing buddies on them for 16 years and never had an issue. Doing the same for my new trailer and so far no issues. Great product!!!


Very high quality, but don't try to replace the hub caps, you don't need them. There may not be quite enough room and seating the hubs may unknowingly cut the soft rubber cover of the Bearing Buddy under the cap. And if you do damage the rubber cap/cover, make sure to replace it (Needs to stay waterproof). its easy to order another.


Nice job "e-Trailer"; received this "heavy" order very promptly; did not expect it so quickly in view of how other retailers/ manufacturers/ on-line businesses are behind in fulfilling orders. Packages (3) came all intact, well packed and product received in great condition. The order included:
> 5-Leaf Slipper Spring w/ Hook End for 6,000-lb Trailer Axles (2)
> U-Bolt Kit for Mounting 8,000-lb, Round Trailer Axles - 8" Long U-Bolts (2)
> Tandem-Axle Trailer Equalizer Kit for 2" Slipper Springs - 10-1/8" Long Equalizers (2)
> Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 6K (2)
> Mounting Bolts and Hardware for 12" Brake Assemblies (2)
> Bearing Buddy Bearing Protectors - Model 2441SS - Stainless Steel (Pair) (2)
> Bearing Kit, 15123/25580 Bearings, GS-2125DL Seal (4)
> Optronics LED Combination Trailer Tail Lights - Submersible - 40 Diodes - Driver and Passenger Side.
These items are being utilized in the total suspension replacement of a 10,000 gvwr tandem axle trailer. Good sized job for a DIY'er. I expect that it will give my JD 2038 tractor a smooth and safe ride as it is towed/ hauled down the highway.
Thank you.
I would/will strongly recommend to a friend/relative or associate.
( I'd take a picture of the "project", but there is a vicious rain storm occurring outside; perhaps one or two pics to follow at a later time).


Great Product. Delivered when and as promised. Easy to install and maintain. I wouldn't tow a trailer without them. You can always be assured that you have grease in your bearings. No unplanned roadside bearing repairs!


Bearing Buddies should be on all boat trailers. The hubs warm up as you tow, then you dunk them into the cold water. The sudden cooling off allows a little water to sneak by the seals and that water causes bearing failure, unless you re-pack the bearings regularly. Bearing Buddies have a spring that keeps a little positive pressure on the grease inside the hub so the water can't get in. This pair is stainless steel which is a must for salt water use. (SS at the end of the part number denotes ALL stainless. Don't be confused. The chorme plated versions have SOME stainless and are often listed as stainless when they are not) And they came with the rubber caps too, often sold separately.
As always e-trailer was a breeze to deal with. Right parts, right price, right on time.


These ss bearing buddy's are an excellent, high quality product. Although I've only put about 1000 miles on them, I've launched my boat several times and upon a recent inspection, there were no signs of moisture in the bearings. I would recommend them as I have installed them on two more of my boat trailers as well.


What is horrible about this design is that it uses a press on adaptor for the larger hub bores, and when removing the unit from the hub, for routine inspection, about 50% of the time the bearing buddy comes off and the adaptor remains lodged in the hub. It is nearly impossible to remove the adaptor from the hub without damaging it. A one piece design for the larger bore would net 5 stars.


worked great and got them with no delay. Etrailer was a great source to restore two boat trailers.


Don't get me wrong I think Bearing Buddy's are a great product provided they fit your application. Based on my outer bearing number and cap size the model 2441 Bearing Buddy was supposed to fit. The only problem was that instead of being 2.441" they were actually more like 2.448" and would not fit. After playing the run around game of ordering another set and talking to the factory I took them to a local machine shop and had them turned to the correct diameter. The machinist said that the problem was the shoddy machining of Bearing Buddy and when he cleaned up the rough machining they were at the right diameter. Only trouble was I had to pay an additional $35 to finish the job that should have been done at the factory which by the way is now in Puerto Rico.


Service was great. The wrong bearing buddy's and back seals got delivered. The hubs, and bearings worked great. They were quick to email me a pre paid packing slip to send it back and quickly sent me the right parts.
Very helpful and responsive.


I got 2 sets of these. They fit well, pumped up with grease and I expect they will protect the bearings as they aught.

The only complication is that they don't fit with the hub covers. I had to leave the covers off. I guess I could drill out the covers to allow these to poke through but I haven't.


These Bearing Buddy bearing protectors are great. I use these on many trailers including farm wagons that don't have greaseable hubs. I have used the chrome and now the stainless and like them both. This is the third set I have purchased for trailers and will continue as I find the need.


The new bearings have made all the difference. Easy installation and less maintenance. ordering was very easy


The quality of these fittings are truly top notch. They installed very snugly into the hub and I've filled them with grease. Perfect! oh...and best price I found anywhere. Thanks etrailer!


The Bearing Buddies arrived on time and in perfect condition. They were exactly what I had ordered. The fit was excellent. They will be a much needed safety improvement to our "new" 1995 5th wheel. Thank you so much!


Fit exactly as it should. I installed one, and needed to remove it to remove the hub. I followed the instructions for removal, and the bearing buddy separated from the collar. I was still able to remove hub. Upon reinstall everything seemed to fit back together. Time will tell I guess.

  • Are the Bearing Buddy Bearing Protectors BB2441SS Threaded
    The Bearing Buddy Bearing Protectors # BB2441SS are not threaded. These are simply pushed into place. If you need this same size but that are threaded then the part number you're looking for is # BB2441T-SS instead. Same specs and still stainless steel, just with a threaded portion for the installation.

  • Bearing Buddies for 2.430 to 2.444 Inch Hub Bore
    We do have the Bearing Buddy Bearing Protectors # BB2441 or the Stainless Steel version # BB2441SS for corrosion resistance that are designed to fit hub bore diameters of 2.441 inches. This certainly falls within the range you provided but you might want to try and take one more measurement on your car hauler's hub bore just to be sure it matches.

  • What Size Bearing Buddy to Replace 2-7/16-Inch Grease Cap
    The best way to measure hub bore to determine which Bearing Buddy size you need is with a digital caliper. If you do not own one you may be able to borrow or rent one from a local auto parts store. Your other option is to obtain the outer bearing number from your trailer. You may be able to obtain the bearing number without having to pull it from the spindle; try wiping it clean of grease to see if the bearing number can be read. The size you quoted, 2-7/16 inches, corresponds to 2.437...

  • Can Bearing Buddy Protector be Used on Trailer Spindle with Grease Fitting
    To install Bearing Buddy Bearing Protectors like the part # BB2441SS that you were looking at on trailer spindles that feature a grease fitting you will indeed need to remove the zerk fitting first. This is simply because the Bearing Buddy won't fit to the hub properly with the grease fitting behind it on the spindle. With the fitting removed the Bearing Buddy will fit and work great as long as it is the correct size for your hub. This particular model is designed to fit a hub bore diameter...

  • Determining if Bearing Buddy Bearing Protectors # BB2441SS Will Fit 4,400 Pound Dexter Hubs
    Most likely the Bearing Buddy Bearing Protectors # BB2441SS that you referenced are the correct units for the hubs on your Dexter 4,400 pound axle, as the hubs should use the # LM67048 outer bearing. With this in mind I do still recommend verifying your hub bore diameter to be sure. These are designed to fit hub bores with a diameter of 2.441 inches. As you can see the measurement is very precise so I do recommend using a digital caliper that can measure to 3 decimal places.

  • Should New Bearings Be Packed Prior To Instillation If using Bearing Buddies?
    I recommended removing all of the old grease and packing the new bearings prior installing them. When you install the Bearing Buddy Bearing Protectors - Model 2441SS - Stainless Steel (Pair) Item # BB2441SS you can add more grease with a gun to help make sure everything is fully packed. You want to make sure you use the same grease as some different greases cannot be mixed.

  • How to Determine Which Bearing Buddy Bearing Protectors Will Fit a Boat Trailer
    The best way to determine what size grease caps or Bearing Buddies will fit your hubs is to pull a hub off of the trailer and get the inner and outer bearing numbers stamped into the metal of the bearings. With those numbers I can determine many replacement parts for your hubs including which Bearing Buddies fit. Another way is to measure the inner diameter of the hub bore (where the Bearing Buddies will fit into). You will need to use a set of digital or dial calipers to get the most...

  • Replacement Bearing Caps for a Boat Trailer with 4.4K Axles
    For a boat trailer like yours, I recommend going with a Bearing Buddy that will keep the water out. With a gross vehicle weight rating of 8026 pounds, you probably have 4.4K axles. The appropriate Bearing Buddy will be part # BB2441SS. This will fit inner hub bores with inner diameters of 2.441", so be sure to measure yours to ensure it's correct. If, by chance, your hub bore is threaded, then use the Bearing Buddy with threading, part # BB2441T-SS. I've linked to video reviews of both...

  • Recommended Bearing Buddy Bearing Protectors for Montana Travel Trailer
    To determine which Bearing Buddies you'll need, use a digital caliper to measure the inside diameter of the hub bore, not the outside diameter of the grease cap. Given the 2.443 inch dimension you provided, it's extremely likely that you'd need the model 2441 Bearing Buddy which measures 2.441 inches in diameter. They're available in chrome as part # BB2441 or stainless as part # BB2441SS. If your hub bores are threaded, use part # BB2441T-SS. I'd still recommend you measure for confirmation.

  • 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.

  • What Bearing Buddies do You Recommend for My 2017 Coyote Trailer Hubs?
    Without knowing what exact hubs you have installed on your 2017 Coyote Trailer, you need to know the hub bore measurement in order to know what Bearing Buddy size you need. The best way to do this is to measure the opening to the hub to the third decimal place using a digital caliper. Once you know your bore measurement, you simply select the correct Bearing Buddy that fits your bore. For example, the Bearing Buddy Bearing Protectors - Model 2441SS # BB2441SS fits 2.441" hub bores.

  • Which Bearing Buddies Will Fit a 2-7/16 Inch Hub Bore
    You will likely need 2441 model Bearing Buddies: # BB2441 for chrome or # BB2441SS for stainless steel. Your hub bore will be slightly less than this if it is exactly 2-7/16 inches and that ensures a tight fit. The hub bore should really be measured using calipers such as # PTW80157 because the measurement has to be as accurate as possible.
