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.

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. 380637

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). 812005

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.

Ask the Experts about this Bearing Buddy Trailer Bearings Races Seals Caps

  • Which Bearing Buddy Fits 5,200 lb Dexter Axle
    For your Dexter 5,200 lb hub the Bearing Buddy part # BB2441SS is the correct fit. Installing it is pretty easy. Using a flat board and a mallet you'd lightly hammer it into place.

  • What Size Bearing Buddy for Kodiak K2HR526D Disc Brake Kit
    Yes, the correct Bearing Buddy to use with the Kodiak Disc Brake kit part # K2HR526D that you have is the part # BB2441SS.

  • 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 like # 301-17068.

  • Correct Grease Caps for an Axle Equipped with a Grease Zerk
    It sounds like you have an EZ Lube type of spindle, that has a grease zerk on the spindle. You are correct that the standard grease caps do not provide the proper clearance for this style of spindle. With the bearing numbers that you provided I was able to determine that outer diameter of the grease cap that you will need is 1.986 inches. Then the correct grease cap fitting for your is the TruRyde EZ Lube Grease Cap # RG04-040. These grease caps have a removable rubber center portion...

  • Bearing Buddies for Trailer with Inner Bearing L68149 and Outer Bearing L44649
    Are you sure the outer bearing is not L44649? If it is then you can use # BB1980A-SS or # BB1980A. With an inner bearing of L68149 the matching outer bearing is most likely L44649.

  • 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...

  • 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.

  • What to Measure to Get the Correct Bearing Buddy
    Sounds like you are trying to pick out the correct Bearing Buddy for your trailer's hub. To do this you will need to remove your current grease cap and measure the diameter of the hub bore. With that measurement you will be able to pick out the correct Bearing Buddy to fit your hub. The part # BB2441SS that you referenced would fit a hub bore of 2.441 inches, if that is what you have then this would be the correct one for you. If not, check out the link I attached that will take you...

  • 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...

  • 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...

    The correct grease/dust cap size for your Kodiak Disc Brake Kit # K2HR526D is 2.44". For EZ Lube grease caps with this dimension we have part # RG04-080 which comes in a quantity of 2. If you are wanting to upgrade to Bearing Buddys (which would require you to remove the grease zerk on your spindle) we have these both in Chrome # BB2441 and Stainless Steel # BB2441SS. The advantage of the Bearing Buddys over the EZ Lube is that the Bearing Buddys give you an easy way to add grease and...

  • Which Bearing Buddies Will Work with Kodiak Disc Brake Kit 12 Inch Hub Rotor
    I took the measurements and specs from the bearings on part # K2HR526D, and matched up the specs to determine that the Bearing Buddies that you need are Bearing Buddy Bearing Protectors, part # BB2441SS. These will work perfectly with your Kodiak Disc Brake Kit, part # K2HR526D. I have linked a video overview on bearing buddies that you may find as a good reference.

  • What Parts Needed When Replacing Disc Brake Rotors # KHR12D on Boat Trailer
    When replacing the disk brake rotors on your trailer it is recommended that you also replace your bearings, races and seals at the same time. This will ensure that all components are new and in good order and will prevent the need to dismantle your trailer again to replace an older part that may wear out before others. The bearing kit for this rotor is part # BK3-100. I have included an article that covers the process of replacing bearings, races and seals on a trailer hub. The Kodiak...

  • 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.

  • 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.

    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.

    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.

  • 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.
