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!



by:

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!



by:

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.



by:

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



by:

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



by:

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.



by:

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



by:

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



by:

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.



by:

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).



by:

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.



by:

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 edtrailer.com 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!!!



by:

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.



by:

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.



by:

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!



by:

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.



by:

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.



by:

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.



by:

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.



by:

Installed bearing buddies on a Ram-Lin trailer which hauls an airboat...they are working as advertised...very happy with your product



by:

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.



by:

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



by:

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!



by:

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



by:

This is my second order in the past month, I was impressed with the ease of finding the parts,and ordering . The price was very reasonable, shipping was very timely. My son who lives in Alhambra IL. put me on to this site, he has ordered from etrailer many times before. I also like it that they accept pay pal. I really like the instructional videos that they sent.

  • Recommended Disc Brake Kit for Trailer With Tandem 5200 lb Axles
    I suspect what you have is what's known as a 5200 lb axle. Assuming your axle uses the 25580 inner and 15123 outer bearings which are typical on axles with capacities of 5200-6000 lbs, and your existing wheels have a 6 on 5-1/2 inch bolt pattern, the Kodiak # K2HR526D disc brake kit you'd looked at would work great for you. The kit includes 2 hub/rotors, 2 brake calipers and 2 caliper mounting brackets as well as the bolts for mounting the calipers to the brackets. For a tandem axle trailer,...

  • 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.

  • 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...

  • Can Bearing Buddies Be Installed on 2002 Springdale Clearwater Edition
    Yes, you can replace the dust covers of your hubs with Bearing Buddies like the part # BB2441SS which fit hub bores that are 2.441 inches. You'll need to remove the caps you have now and measure the opening with a caliper like part # PTW80157. The # BB2441SS fits a hub bore of 2.441 inch but if you have a different dimension check out the link I attached that has all of the ones we carry. If your trailer has a 4,400 lb axle you most likely would need the # BB2441SS or if you have a 3,500...

  • Bearing Buddy for 2-3/8" Grease Cap
    A measurement of 2-3/8" is equal to 2.375" and there are a number of bearing buddies that are close to that measurement. In order to determine the exact replacement you need, you'll have to use a digital caliper such as # PTW80157 and measure your hub bore for the exact measurement. Your other option would be to take a look at your outer bearing, as that will also tell you what you'd need. Bearing Buddy # BB2240 fits a 2.240" hub bore and works with 1700 series outer bearings.

  • 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. I have attached a short video review that you can check out as well.

  • Is There a Bearing Buddy that is Threaded Comparable to a 2240?
    I contacted Bearing Buddy to see what threaded cap they recommend for your application to convert from oil bath to grease. They said that the Bearing Buddy Bearing Protectors, # BB2441SS, is most likely the application for your trailer based on the 2240 question. This Bearing Buddy threaded grease cap has 12 threads per inch, as does # BB2080T-SS, but there are other threads like the # BB1980T-SS which has 24 threads per inch.

    You are correct that the zerk fitting on your spindle will need to be removed for you to use the bearing buddy, but the great part is the bearing buddy will be able to push grease through the spindle providing grease through the spindle to the inner bearing. To find the correct bearing buddy you will need to use digital calipers like # PTW80157 to measure the inside diameter of your hub since each bearing buddy is made for a certain sized hub.

  • Bearing Buddy For A Straight Spindle With An Outer Bearing # LM67048
    When doing some research with the Outer Bearing # LM67048 you provided, the flange diameter of your hub should be 2.44 inches. The Bearing Buddy Bearing Protectors # BB2441SS fits with a 2.441 inch hub bore. The bearing buddy is constructed of stainless steel.

    There are a few different Bearing Buddy Bearing Protectors that are close to 2-3/8" in (2.375") diameter, so I recommend measuring your hub bore with a set of digital calipers like # PTW80157 to get a precise measurement. The available options are the Bearing Buddy Bearing Protectors - Model 2328 - Chrome Plated (Pair) # BB2328 which fits hubs with a 2.328" hub bore, and the # BB2441SS which fits a 2.441" hub bore. I included videos for both of the products mentioned for you to take a look at.

  • Is there a Trailer oil Bath Hub Oil Cap for a Dexter 6,000 Pound Axle
    The 21-36 oil cap, # RG04-270, fits 9K (after 10/1989) and 10K GD (2 piece drum), and 10K to 15K Dexter axles. The 21-35, # RG04-230, fits 6K to 8K ( and 9K before 10/1989) Dexter axles. It would be too large with its 2-7/8 inch thread diameter. All of these oil caps are for oil bath hubs. If you are replacing a dust cap, you probably have regular hubs. For bearing protectors measuring 2.441 inches, go with the stainless steel bearing Buddies, # BB2441SS, or, if the hub is threaded, #...
