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.

The original Bearing Buddy bearing protectors are the only way to go for wheel bearing protection. I put a set on my old 1970’s utility trailer that still has the original axle and hubs with threaded dust caps. Etrailer had the 1980T-ss bearing buddies in stock and got them to me asap. Perfect threaded fit. Sure beats breaking them down to grease!


I ordered parts from information given from your Q and A about my specific application and the information given was incorrect. When returning the product I was charged $xx for return shipping. I supposedly saved $xx on shipping because the order was over $xx, so if it cost your company $xx to ship to me, why does it cost $xx to ship it back ???? Will not be doing buisness with your company in the future.


I haven't move the trailer after I put the BB1980T-SS grease cap on it. They started on pretty good then got harder about mid way on, so I got a pipe ranch to get them all the way on but over all it wasn't very hard to do it only took about 15 minutes to complete the project which is good. They really set the trailer off because the trailer is painted Black.

William H.


Yes the cap work OK guess I made one trip with them. It was from my home at Gulf Breeze Tiger Point, FL back to Sulphur Rock, Indepentence Co, AR which is about little over 600 miles one way and they did really great.


I have a 1969 Metzendorf camper that I just had new bearings installed on. I wanted to put bearing buddies on it so I can grease them on long trips. I wasn't sure what size I needed and they needed to be threaded . I sent etrailer a message one evening asking which bearing buddies I needed and I received a message the next morning with the answer to my question. I ordered them and I received the tracking information for my order. I received them in a few days and my son installed them for me . They fit perfectly!! I'll be sure to order from etrailer in the future and I'll tell my friends what good service I received.


I have these on all of my trailers/ camper. Cheapest insurance you can buy. These are the threaded kind for my equipment trailer.


Three out of the four parts I received are only threaded on half of the diameter and unusable. The pictures are of the same piece and you can see the side with the label has incomplete threads. Big waste of $xx. Save your money!


Etrailer is the model for fast shipping


I bought these ( BB1980T-SS) to convert my Reliable oil bath hubs (EZ-Loader trailer) to greased hubs. The oil caps on my hubs are listed as 1.980", but these do NOT fit the 1.980 Reliable oil bath hub, even though .they're advertised as fitting all threaded hubs. According to Bearing Buddy the ones needed are their 2080T-SS model. These have the look and feel of a very high quality product, would have given them an excellent rating if not for the confusion over the correct sizing.

Allen E.


I purchased the 2080T-SS bearing protectors which the Bearing Buddy people tell me is the correct size for my hubs. Havent installed them as yet as I had to refill the hubs with oil when I received the wrong size Bearing Buddys. Ill probably do the oil to grease conversion this Fall, or next Spring.


The complete shipment arrived on time as usual for However, the label was missing the name of my business and the Owner/Proprietor of the mail service I use was not going to accept the packages for lack of a name. The box number was printed the the name section.

The Owner/ Proprietor is this very small town is the ONLY mail service we have here. So, thinks very powerful by reading every label and wielding her monopolistic power upon everyone. I pleaded with her to let me have package, and she finally agreed, if I would chew your butts for missing the name

Here in this town of [town] Montana we have named her the "Mail Nazi"!

I suggest you be conscience of proper mail labeling.

Otherwise, thank you for your consistent service and prompt customer service!


Good selection for my snowmobile trailer, by ski boat trailer, my fishing boat trailer and our motorcycle road racing enclosed race/shop trailer. My first stop for my trailer needs. This product is hard to find - lot's of places carry bearing buddies in the 1.98" press-fit size - even the local auto shops - but try to find the threaded version? That's when you go to, knowing that its pretty certain they have the stuff you want and need. Quick shipping, good communication - rock stars for your trailering needs.


I have a '66 Avion with GM hubs and wheels. The threaded grease cap was damaged and I had a lot of trouble trying to find a replacement. These threaded Bearing Buddy's worked perfect and added the convenience of being able to add grease! I'm going ahead and replacing the rest of the grease caps as well.


Perfect fit. Timely delivery. I could not ask for more. They are protecting my 1966 Shasta trailer with a single axle. I need to be able to easily check and lube these bearings and these do the job perfectly.


We have 5 trailers of different types, if bearing buddy didn’t come already installed we install them . I have never lost a wheel bearing Assembly because of lack of grease , This product is well made and will last as long as you own your trailer.


I recently purchased two of these bearings to replace my ( Reliable ) oil bath caps on my easy loader trailer. I have yet to install them but was very pleased to find that a threaded model was available and if they work as well as I expect I will replace the other two in the future.


etrailer did everything right, shipped same day, gave tracking advice, fair price for product and shipping. Follow up upon delivery all reasons to recommend, and buy from etrailer again


Threaded bearing buddy. I used it on a 1955 travel trailer. There threads were the right pitch but thread diameter was too large on the bearing buddy. I made it work after cursing.


Never thought that I would find a threaded Bearing Buddy. eTrailer had what I needed in stock and had them to my door in just a few days. Installed without a problem. Thanks AGAIN eTrailer!!


Customer service (Sara) was outstandi ng.


Quality parts at reasonable prices! With a friendly staff especially Eric P! He's my go to man!


The original and still a great product. I have threaded hubs and could not find anyone else that made a product for them. Bearing buddies work great. They're easy to install and easy to maintain. My shortest trip with my boat is about 45 miles and my longest is over 700. I wouldn't dream of traveling without them.


I had some difficulty finding the correct fit for my requirements on your site, and called your customer service number. This was totally not the fault of your site, it was just a difficult item to be sure about fit, and size. The person that I spoke with was very knowledgeable, social, and helpful. Everything worked perfect, and my parts are installed exactly as required. Thank you and keep up the good work.

R. S.


I couldn’t find them until I looked at etrailer. Great company.


Easy to find and order my special threaded Bearing Buddies.
Excellent communications throughout the entire order and shipping process.
I received package two days after it arrived because it required a signature. Had to travel to PO to pick it up. Did not like that as the USPS normally just drops stuff off.
Would have given an excellent if not for that.


These things are great. I have them on my bass boat , utility and pop up trailers


Very pleased with the product. Great video on installation. Experience with etrailer Was even better. Madison P was exceptional with her help. Overall a truly great experience

  • Recommended Bearing Protectors for Boat Trailer Hubs with a 1.98 ID
    If you have a hub that requires the protector to be threaded in I recommend the Bearing Buddy Bearing Protectors # BB1980T-SS, but if you just need protectors that you tap into the hub with a block of wood and hammer, then I recommend the Bearing Buddy Bearing Protectors # BB1980A-SS. Both of these will fit a hub with an Inner Diameter of 1.98 and are constructed of stainless steel which will help prevent corrosion. They have a grease zerk fitting to make it easy to add grease and a cover...

  • Difference Between Bearing Buddy BB1980T-SS and BB1980A-SS
    They are not the same. The Bearing Buddy # BB1980T-SS are threaded into place, and not driven in. If your hub bore is threaded, that's the model you'd need. If your hub bore is NOT threaded, you'd use part # BB1980A-SS. The difference between the # BB1980A-SS and your older BB1980SS is the # BB1980A-SS has the auto check feature that allows you to easily see at a glance whether the hub needs grease added, while the older model didn't have that feature.

  • Recommended Bearing Buddies to Replace Old 1.981 Inch Bearing Buddies
    In order to find the correct Bearing Buddies you will want to get the most accurate hub bore measurement you can get. If you can't get the measurement without pulling the hub you will need to pull the hub to make sure. From the measurements and part numbers you provided, along with the old ones you have, it sounds like you need the Bearing Buddy Bearing Protectors - Model 1980T-SS - Threaded - Stainless Steel (Pair) # BB1980T-SS.

  • Do 1980 Bearing Buddies Insert or Thread Into Trailer Hub
    The Stainless Steel Bearing Buddy Bearing Protectors - Model 1980A-SS w/ Auto Check # BB1980A-SS just seats into the hub. If you're needing the style that threads into the hub then you need the kit # BB1980T-SS instead.

  • Recommended Bearing Buddy Bearing Protectors for 1.98 O.D.
    I took a look online and the closest thing we have to matching the caps in the vault service kit is going to be the Bearing Buddy Bearing Protectors item # BB1980T-SS. The caps on the bearing buddies will allow your boat trailer wheels to be completely submerged. They provide easy access for lubing your axles. I have linked an installation video below.

  • Bearing Buddy to Fit Boat Trailer Hub with 1.9-Inch Threaded Hub Bore
    The Bearing Buddy Threaded Bearing Protectors you referenced, part # BB1980T-SS, are the only ones that are close to your hub bore measurement of 1.9-inches. The other two sizes are both over 2-inches. These should fit your threaded hubs. Please note that the depth of the threaded portion of this part is 5/16ths of an inch. Bearing Buddy recommends using Perma-tex or another grease proof gasket cement when installing these bearing protectors.

  • Depth of BB1980T-SS Bearing Buddy Bearing Protector
    Before it's filled with grease, the spring loaded piston is recessed by about 5/8 of an inch inward from the outside edge of the Bearing Buddy. This distance will decrease as grease is added. The top of the zerk fitting is located 1/4 inch from the outer edge of the Bearing Buddy. I've showed these dimensions in the provided photo.

  • Threaded Bearing Buddy Recommendation for Oil Bath Hub with Outer Bearing L44649
    Most likely you'd need the part # BB1980T-SS as this it the kit commonly used for hubs that have outer and inner bearings of L44649. Since we don't know your inner bearing or hub bore diameter it's hard to say for sure but most likely this is correct.

  • Locating Correct Bearing Buddy to Replace Turbo Lube Cap on Trailer Hub
    I was unable to find any information on the turbo lube cap mentioned in your question. To determine the correct Bearing Buddy replacement, you will just want to measure the pilot hole on your existing hubs. This will ensure that the Bearing Buddy will fit into place on the hub. For example, the Threaded Bearing Buddy Bearing Protectors # BB1980T-SS you were looking at are designed to fit 1.980 inch hub bores.

  • Is it Normal For Trailer Axle to Not have Grease Fitting
    Not all trailer axles have the EZ lube zerk fitting so what you have is totally normal. You can use a Bearing Buddy like you mentioned but we have found is that the Bearing Buddies make it too easy to add too much grease which then blows out the grease seal. We recommend packing the bearings by hand like you can see in the attached video.

  • Threaded Bearing Buddies for 1.988 Inch Hub Bore
    Bearing Buddies # BB1980T-SS are going to be the best match for your 1.988 hub bore. Nothing else we have comes close.

The Bearing Buddy size to match the hub bore dimension is the 1.98-inch type, such as # BB1980A-SS in stainless steel or # BB1980A in chrome finish. These are non-threaded. For a threaded Bearing Buddy in this size use # BB1980T-SS.

  • Replacement Bearing Protectors for Older Boat Trailer With 1-63/64 Hub Bore
    The size bearing protector (Bearing Buddy) or dust cap needed is based on the hub bore diameter. 1-63/64 translates to roughly 1.98 inches which is what the # BB1980A-SS stainless or # BB1980A are designed to fit. The easiest way to confirm this is to pull the hub and check the reference number on the side of the outer bearing cage. If it's L44649, L44643 or L44640 and your existing bearing protector is driven in and not threaded in, either of these would work perfectly for you. Since you're...

  • Difference Between Bearing Buddy 1980 Models
    The model 1980 Bearing Buddy simply means that they fit a 1.980 inch hub bore. There is one difference of note between Bearing Buddy Bearing Protectors # BB1980A (Chrome Plated) or # BB1980A-SS (Stainless Steel) and the Bearing Buddy Bearing Protectors # BB1980T-SS which is that the latter - with the "T" in the part number - means that it is threaded and fits internally threaded hubs.

    The Bearing Buddy Bearing Protectors part # BB1980A for chrome or part # BB1980T-SS for stainless steel fit a 1.980" hube bore. This is more than likely what you need as it is the most common size so this is what I recommend using.

  • How to Choose Correct Bearing Buddy Bearing Protector
    In the exact situation that you are referencing the measurement taken was in-between Bearing Buddy sizes so it would have been better to use one slightly larger than one that is slightly smaller as a smaller size wouldn't be able to remain installed properly. If you already have Bearing Buddy protectors installed on your trailer then you can use a digital caliper to measure the inside diameter of your hub bore OR you can measure the outer diameter of the part that fits into your hub from...

  • Correct Bearing Buddy Size for a Kokopelli Trailer that Takes 7700121 Bearing Buddies
    I did some checking and the number they gave you corresponds to the 1.980 Bearing Buddies. There are a couple of options in this size: Stainless steel with auto check # BB1980A-SS Chrome plated with auto check # BB1980A Threaded stainless steel # BB1980T-SS It does not appear that your trailer uses the threaded version so either of the first 2 sets will work.

  • How to Pick Out Threaded Bearing Buddy for Replacing Oil Bath Cap
    I wasn't able to find any reference to your oil cap or dimensions so what you'll need to do is measure the diameter of your cap so that we can determine if there's a threaded Bearing Buddy that would work. For example, we have the part # BB2080T-SS for if your hub bore is 2.08 inch in diameter, part # BB1980T-SS for 1.98 inch, or part # BB2441T-SS for a bore of 2.441 inch.
