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.

Stellar eTrailer.com Tech and Customer support and quality product.
I have an imported folding trailer (HF 90154) & they do not stock protective hub covers for their trailer.
I contacted their customer support they provided me the hub dimensions (dust cap by diameter 52mm) , I then shared that info with etrailer tech support who directed me to the right bearing buddy product that I needed (2.047" or part# BB2047).
They shipped and delivered it in a timely manner. I installed it this morning and it seems to be working flawlessly as I would have expected from bearing buddy!

A year later and the bearing buddy is doing its job with no issues to report! I know where to go when I need expert Trailer assistance - eTrailer!
by: Gregg09/07/2013
Bearing Buddy is a good product. I had to use a block of wood and a small sledge hammer to put them on. They would not go on with a rubber mallet.
I measured 2.045" and the closest one from Bearing Buddy was 2.047"They are on and will not come off.... The trailer is a kit that I bought at depot in 1997... I would recommend

theses also work for the northern tool 5 x 8 trailer... hard to find this sizethanks fits great
by: Willisonthefly08/08/2023
These are fantastic and actually fit the harbor freight hubs which are tough to fit. I bought these after losing the original hub covers and then suffering a complete bearing malfunction on a rafting road trip. Lesson learned. These allow me to keep the bearing greased on a regular basis with no mess. Easy to use and they create a vacuum to protect everything inside. Very intuitive.
by: hjrjolie06/07/2019
Fast Shipping. Installation easy, fits well, grease expanded into cap just as described. Looking forward to many years of bearing life without having to pack the bearings again and again.

Myself, I have been looking for nearly 3 years for the correct size, 2.047 and it was my friend that located your site. Both went on very snug. In the past I would purchase smaller ones and twist the
inner surface and shove them on with little effort and then fly off during my travels. These Bearing Buddys went on Solid ! Harbor Freight wasn't any help at all.
by: James 07/30/2023
awesome addition and so much better than doing the old-school method of packing the bearings with grease.

Quick delivery, great price. Using on hubs of a pull behind motorcycle touring trailer to keep the bearings lubed.

Very tough to find size bearing cover. Not even the Specialty trailer shop in my area didnt have them. etrailer had them and shipped them out fast. Great website made finding what I need easy.
by: Paul M. 10/07/2014
This things are great. They arrived just in time and they fit perfectly on my Harbor Freight trailer.
by: Al F.08/26/2017
Installed the BB2047 Bearing Buddies on a Detail K2 MMT 5x7 trailer.
The trailer hub has a 1/8" grease fitting on the backside which is inaccessible even to a contortionist and the maintenance instructions call for repacking the wheel bearings by hand annually or every 2000 miles.
The best alternative for a 75 year old arthritic was obviously the Bearing Buddies.
They arrived as promised and each grease cap was changed out in less than 2 minutes.
The annual repack will be replaced with a couple of strokes of the grease gun on occasion as needed.
It doesn't get any easier than that.

Working out just fine. Need to be less generous with my grease applications to avoid excess passing the rear seals and getting thrown onto the back side of my wheel rims.
by: Sam 05/19/2023
they fit perfectly, thanks to other reviews about Harbor freight trailors.
by: Steve D.03/25/2015
The Model 2047 Bearing Buddy bearing protectors were a perfect fit for the wheel hubs on the Harbor Freight heavy-duty trailer that I am using as the base for my new home-built teardrop camper. Installation was straightforward and only took a few minutes per side. I am looking forward to many years (and miles) of trouble-free wheel bearings now that these bearing protectors are installed.

Bearing Buddy is still doing its thing after a 7136.5-mile trip out West over 34 consecutive days during the Summer of 2015. A shorter, 1500-mile roundtrip was made to SC in December. Overall, Im totally satisfied with the Bearing Buddy x2 performance thus far and cant wait for the weather to warm up a little more to take my little tear camper back on the road. Ill be heading east to New England this summer.
by: Thomas 08/03/2023
Well made, heavy duty. Fit well no trouble installing. Still in the hub after lots of bumpy road travel.
by: Keith V06/20/2020
I am very pleased with the bearing buddy. I had lost the bearing cap and couldn't find a replacement at any auto shop. However, the BB2047 fit perfectly and keeps my bearings lubricated continuously. Replacing the cap did force me to repack the bearing, but that was probably a good thing as water had gotten in there. I feel the bearing buddy will protect my bearings probably for the life of the trailer; and since the grease is under positive pressure, water won't get in there.

The bearing buddies have worked flawlessly, my trailer is used not only on the road, but in the woods and dusty locations. The bearing buddies have never ped off, and keep the bearings well lubricated a clean.
by: Brian B. 04/27/2017
Excellent upgrade for my utility trailer. Easy to install and a very beneficial way to monitor and add grease to the wheel bearings. I previously had to pull off the trailer wheels to repack the bearings with grease but now I add a few pumps of grease before every road trip. My bearings will last longer and I have peace of mind. Great product!

Absolutely great!
by: Steve L08/16/2017
Fit perfectly on my 1195 lb. 4x8 foldable trailer. Tapped them in with a wood block and hammer, filled with grease, and installed the rubber covers--all done in less than 5 minutes. Haven't road-tested yet, but no reason to expect any problems.

Just received the pair of Bearing Buddy Protectors for my HarborFreight 1720lb trailer (#94564) - fit perfectly! Took less than five minutes to install, they have a nice tight seal and are now loaded with grease. Looking forward to having almost maintenance-free bearings!

Still working great after a year, Ive had no maintenance issues and have just added grease when needed. Would highly recommend!
by: Rob05/18/2019
The Bearing buddy I purchased looked good but are slightly larger that than the ID of the trailer hub that intended for. I measured it, and did internet searches on the trailer and Bearing buddy was the answer. That said, the Bearing buddy OD appears slightly larger than specified if my caliper measurement is correct. Wasted my money unless I am able to turn down the OD of the bearing buddy. It does look to be a quality product.

This Bearing Buddy is intended to fit a 2.047 hub bore that uses a 07204 bearing race, and is meant to be a very snug fit, to the point where its suggested that a mallet or a dead blow hammer and a block of wood be used to drive it into place.
by: Steve08/28/2018
I was very impressed with my transaction with etrailer. Certainly, the customer service rep was the key to my satisfaction. She was knowledgeable, SO courteous! The bearings were a perfect fit! All is well and I will shop with etrailer again

Great !!!! Such a small feature for a great deal of security in knowing that the bearings will no fail. Been There, Done That !!!
by: Andrew 04/05/2021
After trying to buy bearing protectors at Harbor Freight, (my mistake) they don't even sell the right size for their trailers. I saw on the etrailer forums that several others had the same issue and the techs had recommended the correct size. They came in this week and I installed them. They were very snug, but once lined up they went right in. Worry free now.

See what our Experts say about this Bearing Buddy Trailer Bearings Races Seals Caps
- Why Would Bearing Buddy of Trailer Hub Fall OutIt's definitely possible that something happened to the center bore of your hub where the Bearing Buddy/dust cover usually fits and that is why it keeps falling out like you described. Easiest way to determine that would be to take a digital caliper like the part # PTW80157 and measure the bore and then compare it to the other hubs to see if there's a difference. It sounds like yours happens to be bigger somehow. You might need a new hub which to help with that I would need to know the...
view full answer... - Recommendation for Replacement Hub With 30205 BearingsThe bearing you have is actually a 30205 bearing which has an inner diameter of 0.985 inches. From what I could find, this is a common bearing used on the Harbor Freight trailers. With that being said, we do not have a replacement for this, unfortunately. This is something you would need to go through Harbor Freight for a direct replacement. However, the better option will be to actually replace the axle. This will get you set up with something that is much more common. Something like...

- Is Bearing Buddy BB2047 Thread In or Press InHey Robert, the Bearing Buddy part # BB2047 is not threaded. It would get tapped in.
view full answer... - Bearing Buddy Sizes Compatible for Hub 2 Inch Inner DiameterThere are a couple of sizes close to your 2 inch diameter. If you measured with a digital caliper that goes to the thousandths then that will be much easier to determine the fit. We have the 2.047 inch # BB2047 in chrome plated or # BB2047SS in stainless steel. We also have the 2.080 inch # BB2080 in chrome of # BB2080SS in stainless steel. If it is smaller we have the 1.80 inch # BB1980A-SS in stainless steel. The fit should be snug to prevent leaks so I've attached a video...
view full answer... - Can Bearing Buddy be Used on Travel Trailer with Electric Brakes While Bearing Buddies are typically seen on boat trailer for marine use, there is no reason they cannot be used on a travel trailer like yours. They will do a great job of keeping dirt and moisture out of the hub and allow for easy access when greasing the bearings. In order to choose the correct Bearing Buddy for your trailer, you will need to measure the inside diameter of your hub bore. I recommend using a digital caliper like # PTW80157, as the measurement will need to be exact. Also,...
view full answer... - Grease Cap/Bearing Buddy Availability for Harbor Freight Utility TrailerWe have found that the Bearing Buddy part # BB2047 fits several Harbor Freight Trailers. Including the following trailers 90154 42709 90153 42708 2575 2948 Or, you can measure the bore of your hub where the cap would go with a digital caliper like part # ALL641130 to see what cap you would need. Once you know the size you need check out the link I attached to see all of the caps we carry. You will need to select your size from the filters.
view full answer... - Can Bearing Buddies BB2047 be Added to Camper TrailerYour camper trailer can absolutely use the Bearing Buddies like the Bearing Buddy Bearing Protectors - Model 2047 # BB2047. These simply replace your existing grease caps and won't get grease into your brakes; they will keep your hub and bearings better protected from dirt and water than standard grease caps so they are a good addition for your trailer. You just need to make sure you have the correct ones, and to do that you will need to measure the hub bores on your trailer's hubs using...
view full answer... - How to Measure for the Correct Dust Cap?If the bearings you took off of your boat trailer match the new ones then you'll have the correct bearings. To replace the dust covers you are going to want to measure the inside of the hub where the grease cap inserts or you can measure the outside edge of the cap behind the ridge where it inserts into the hub. The diameter does need to be a precise measurement so you will want to use the Performance Tool 4" Carbon Fiber Digital Caliper item # PTW80157. If you are worried about the bearings...

- Will the 2.047 inch Bearing Buddy Fit a Bore Size of 2.012 inchesI believe that the bearing buddy that you hub bore diameter that you saw was the 2.240 inch size, part # BB2240, which will be too big to fit in your hub bore size of 2.012 inches. The next step up from the # BB1980A that you purchased (which fit hub bore size 1.980) will fit the hub bore size 2.047 inches and is part # BB2047. Since you want the fit to be as accurate as possible this size will be too big. I called Bearing Buddy and my contact confirmed this. Custom-built trailers can...
view full answer... - Bearing Buddy Recommendation for a Harbor Freight TrailerI actually called Harbor Freight about your trailer to determine what size dust cap is used on that trailer. I reached a tech and he stated that the dust cap is 52mm or 2.0488 inches. It looks like the best option is # BB2047 or # BB2047SS . However, you normally want them to be slightly larger than the hub bore to fit snugly.
view full answer... - Determining if Bearing Buddy Could Fit 2006 Forest River Rockwood Freedom 1910We don't have a way to determine that from here but if you can pull off one of your current caps and measure the bore of the hub where the cap goes we can verify if the part # BB2047 would fit. If the dimension you find is 2.047 inch this would be a fit. Another really common size that might be correct is the part # BB1980A which fits the bore size of 1.98 inch.
view full answer... - Closest Hub Grease Cap Recommendation for Hub with Bore of 2.035 inchesThe closest cap/protector we have for your hub is the BearingBuddy part # BB2047 which is for hub bores that are 2.047 inches in diameter. This is slightly larger than what you listed so you might want to try remeasuring yours hub with a digital caliper like the part # PTW80157 to verify.
view full answer... - Correct Bearing Buddy For A 40 x 48 harbor Freight Trailer With A 4 Lug HubLooking at there 40 x 48 harbor freight trailers, It appears to come with a 4 lug hub similar to the # AKIHUB-440-2-G-1K that we carry here. All of the 4 lug idler hubs we carry would use a grease cap with a diameter of 1.98". Provided your trailer uses the same standard size, the correct bearing buddy will be # BB1980A-SS. You could always take a micrometer or caliper to the pilot hole in the hub to confirm the size.
view full answer... - Determining the Appropriate Bearing Buddy Size Using Bearing Part Numbers and Existing MeasurementsTo determine which Bearing Buddy would fit your trailer you will need either a measurement of the hub on your trailer, or the bearing part numbers. To measure your existing hub it is recommended to use digital calipers to get a precise measurement. The measurement needs to be of the inner diameter of the hub bore. Once you have that measurement then you can choose the Bearing Buddy that is the next size larger. The most reliable method to identify parts for your trailer is via part...

- Bearing Buddy and Standard Grease Caps to Fit 1.98-Inch Hub BoreAll Bearing Buddy bearing protectors have the same depth, just different diameters. Also, some are threaded to fit threaded hubs while others are not. If your spindles have a grease zerk fitting on the end you will not need to use a Bearing Buddy; that grease zerk means you have EZ-Lube spindles which provide an alternate way to maintain your hubs grease level. For such spindles use part # RG04-040 If it is the actual castle nut that hits the inside surface of the Bearing Buddy then you...

The bearing protectors closest to your OD measurement of 2.02 inches is either going to be 1.98 inches or 2.047 inches.

- How to Pick Out Replacement Trailer Axle for Harbor Freight TrailerHarbor Freight trailers don't use standard trailer axles so replacing the hubs gets challenging so replacing the axles would be the way to go. I'd need the distance between the spring centers of your current axle as well as the distance from hub face to hub face and I'd be able to pick out the correct axle for your application. You'll also need the bolt pattern of the wheels you have to pick out which I attached a help article on determining. I also attached a link to a page that has...
