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.

I wasn’t going to write anything, but since feedback was sought out and requested…here it is. The bearing buddies themselves were fine. I followed instructions, used a micrometer caliper to size things, but still ordered the wrong size. That’s not really etrailer’s problem, but mine. The reason I’m not thrilled, is because to return them is so expensive it’s not even worth it. While you get “free shipping” to order, if you have to return them, you have to back pay the shipping, and of course the return shipping as well, so you end up with a few bucks and the inconvenience of a bunch of time spent getting them shipped back. I would rather support the small guy, but on this one, with the sizing being a little tricky, I would have been much better off getting them from Amazon that makes returns easy.


Product was delivered as requested. Overall process was very smooth.



The product solved my issue. I have not had to worry about it since.


I am so happy to get these Bearing buddies. It will save me so much money. I can grease the bearings easily, without hassle and without taking it in to pay someone to do it.

The bearing buddies are excellent. I travel for a living and it is hard to take the tires off to do the bearings while living in an RV park. Now, I can just pull the plastic dust seal and do it in a matter of minutes. I will definitely use them again if I have another trailer that doesnt have access for lubing the bearings.


Simply fantastic service. Adjusted my order on the fly and made sure it got to me on time, for a hassle free long-distance trip. Thank you Carol!

As for the product -- I went with 1980 SS in the end. Easy to install, load with grease. My trailer's wheels were blissfully silent across an 800 mile round trip.

(Now to return the ones I didn't need...)


Shipped earlier than expected. Quality name brand product with boot accessory for better price. Just received and installed in 10 minutes Great Value Strongly Recommend seller 5 stars !



Still keeping my hubs dry, I take my jet skis to the lake 2 to 3 times a month during summer Trailer stays in the water for up to 6 hrs each time No complaints ..just always keep the bearing preloaded with grease


Perfect fitment!


Bearing buddies take much of the concern out of pulling my trailer. thanks


Service at etrailer has been great. These Bearing Buddies are the best, and the pricing is great too. If you ever have a problem, the staff is always there to help you.

  • Bearing Buddy Bearing Protectors for 1.975 Hub Bore Diameter
    The closest Bearing Buddy Bearing Protectors we have to matching the 1.975" inner hub bore diameter you measured are part # BB1968 for Chrome or # BB1968SS for Stainless Steel (rust resistance). As you mentioned in your question these are designed to fit a 1.968" hub bore, so it doesn't match your dimension exactly but it's close enough to fit and work great (this is a difference of just 0.007"). The hub bore is going to be tapered as well which will further seal this cap in place. I...

  • Recommended Bearing Buddy Bearing Protectors for Hubs with Bore of 1.986-Inches
    It sounds like you are looking for a Bearing Buddy bearing protector with a grease zerk fitting for your hub that has a 1.986-inch inner diameter. We offer two choices for your pop-up, either chrome-plated Bearing Buddy # BB1968 or the stainless steel version # BB1968SS. Both kits include two Bearing Buddy protectors and two flexible covers. Take some care when initially filling the protectors with grease to avoid over-filling that could blow out your inner grease seal.

  • What is Next Size Smaller Bearing Buddy than One with 1.98 inch Outer Diameter
    Bearing Buddy does have a size that is slightly smaller than the 1.98 inch one you already tried with the # BB1968 or stainless steel # BB1968SS. It's .012 of an inch smaller in diameter which sounds like exactly what you are looking for.

  • How to Determine the Right Size Bearing Buddy for a Ranger Utility Trailer
    Instead of measuring the dust cap you have, measure the hub bore where the dust cap fits. You need the most accurate measurement possible so using dial or digital calipers is the way to go. Usually the dust cap or bearing protector outer diameter is slightly larger than the hub bore. this is so you have a very tight fit. It sounds like you might actually need a 1.98 inch, which is more common. But measuring the hub bore should tell us. In the event that the hub bore returns a similar measurement...

    For a standard grease cap close to your original's 1.975-inch diameter you can use part # F001610 which is 1.960-inches. If your hubs are not threaded, then for a Bearing Buddy protector you can use stainless steel part # BB1968SS or chrome-plated part # BB1968.

  • Bearing Buddy Recommendation for Hub Bore of 1.97 inches
    For a hub bore of 1.97 inches going with a Bearing Buddy part # BB1968SS would be the closest match. The .02 inch difference would only mean the Bearing Buddy would fit slightly easier.

  • Bearing Buddy Recommendation for Trailer with Hub Bore of 1.975
    It sounds like the Bearing Buddy Bearing Protector # BB1968SS is exactly the Bearing Buddy you would need since it is designed for 1.968 in hub bores and your measurement is very close to that. If you wanted to be absolutely sure I would recommend you pull the outer bearing to see what you have. You most likely will have a M-12649 or 07100 bearing, and if you do then the # BB1968SS would be the correct kit for you.

    The closest fit of any bearing protector we have to a 1.950 hub bore is going to be either # BB1968SS for stainless steel or # BB1968 for chrome plated. These are designed to fit a hub bore of 1.968 inches. Bearing protectors are often slightly larger than the hub bore for a tight fit. But 0.018 inches still might be too large to fit. Make sure that when you measure you are using dial or digital calipers for the most accurate measurement. It also might help if you can tell me the inner...

  • What Size Bearing Buddy Is Needed For A Hub Bore Size Of 1.940 Inches On A 1951 Utility Trailer
    I have a Bearing Buddy Bearing Protector, # BB1938, which fits a 1.938 inch hub bore. This would be the closet to your measurement of 1.940 inches and should work in your hub. The next closest size I would have is the Bearing Buddy Bearing Protector, # BB1968, it fits a 1.968 inch hub bore. The Bearing Buddy Bearing Protector, # BB2047, you have referenced fits a 2.047 hub bore, which would be too big for your trailer.

  • Recommendation For Fitting 2.047" Bearing Buddy Bearing Protectors On Hub With 2.045" Measurement
    You should be able to make your Bearing Buddy Bearing Protectors # BB37SR fit by placing them in the freezer. The cold temperatures will cause the steel to shrink slightly but they will likely have to sit in the freezer overnight to ensure they get cold enough.

    If the 1938 Bearing Buddy was too small the next biggest size is the # BB1968 which is for a hub bore of 1.968 inches. Since this is pretty close to what you thought you had and is slightly larger this would most likely be it.

    What you have are wheel bolts and a hubcentric hub. This means that the wheels center on the hub using the center pilot hole.

Compare that to the pilot hole on the wheels you have to determine if this tire and wheel combo will fit. If it will then you can use it.

  • Which Bearing Buddy Do I Need on My Utility Trailer
    Since the 1.98 inch is just slightly too large then more than likely the 1.968 inch # BB1968 is going to be your fit. To find out for sure which Bearing Buddy you need you can check your bearings. If your outer bearing is M12649 or 07100 then you need the 1.968 inch. If you have outer bearing models L44643, L44649 or L44640 then you will need a 1.98 inch Bearing Buddy # BB1980A. Or if your outer bearing is model 09067 then you need the 1.938 inch # BB1938.

  • Bearing Buddy Recommendation for a Trailer Hub with 1.974 Bore
    The closest bearing buddy we have would be the 1.980 part # BB1980A that it sounds like already tried. The next smallest size we have is the 1.968 part # BB1968 which unless you measured wrong would be too small. I am surprised you couldn't get the # BB1980A to fit. That should be close enough to make it work, it could be that you need to use a hammer and a board to lightly tap it into place.

  • How To Find the Correct Size Bearing Buddy Bearing Protectors

  • Determining Which Diameter to Measure for Bearing Buddy
    You need to use the inner diameter of your hub bore to determine what size Bearing Buddy you need. If you measured the outside diameter and chose your Bearing Buddy on that, then it will not fit. If you measured the inner diameter, then as you said, it's supposed to be a tight fit. To get an accurate measurement of your hub bore, it's best to use a digital caliper like part # PTW80157 as this is accurate to 0.01 inches. Once you have measured, then choose your Bearing Buddy with that...
