Provide your trailer wheel bearings with premium protection - replace your existing grease caps with Bearing Buddies. They install in seconds and provide an easy, safe way to monitor and control the level of grease in your axle hub.
Features:
Specs:
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 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.
Keith V - 06/21/2021Fast 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.
hjrjolie - 06/08/2020Stellar 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!
Thanks for the information, it's good to have.

Patrick B - 4/9/2014 Rick S - 02/20/2015Bearing 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 this product
Bearing Buddies arrived today, I immediately had to install them with no problem whatsoever, great fit. Installed on a Harbor Freight trailer....thank you etrailer.
I use them on a 8 ft 1000 lb rated utility trailer. They simplify an otherwise arduous maintenance chore.
Only Cap that would fit Harbor Freight largest trailer. Works and fits perfectly!
I called to place a order for the grease buddies the sales person was very helpful getting me the right size I need and the product wasn’t very long getting to my house in Oregon this is the second time I ordered the grease buddies from them the first time back in 2016 and I’m going to be ordering another pair soon for my boat trailer
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.
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.
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.
etrailer.com website is easy to navigate with fair pricing. Extremely fast shipping with great tracking by location and route on a map. They have friendly and knowledgeable customer service. My order shipped the next day and arrived a couple of days later. I was very impressed! Since then I found another trailer accessary I need and placed another order yesterday. It actually shipped the same day and I'm tracking it now. Five star experience!
Prompt shipping, fair price, accurate advertising The Bearing Buddy fit my little Harbor Freight Tag a Long trailer perfectly. Your fitment description was spot on. Thanks!
Dirtstiff - 02/18/2018Installed 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.
Al F - 08/26/2018The 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.
Steve D - 03/28/2016Fit perfectly on a harbor freight trailer, solved my problem. Delivery was faster than expected.
Easy to install, makes it easy to grease my 12 year old bearings (yes-the bearings have been on my discount hardware store purchased trailer since built in 2007 and have at least 10000 miles on them with no problem) . No leaks. Great product!
Kevin J - 03/05/2020This things are great. They arrived just in time and they fit perfectly on my Harbor Freight trailer.
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.
Steve L - 08/16/2018The 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.
Mike L - 05/20/2019Very happy with the purchase and the experience of working with etrailer. Great company and great product
These are doing their job well. I have them on a Harbor Freight trailer which gets a lot of use (and abuse). 300 mile trips where the typical driving speed is 70mph. We stop about every 100 miles and the first thing I do is feel the hubs and tires. Hot on either one is a huge warning sign, and these bearing buddies help to keep grease in the hubs which deeps them running well. Really, for any wheel with a hub, bearing buddies are a no brainer. These fit well (with a little finessing - they went in tight), and protect what is arguably the weakest part of any trailer. Don;t bother with knock off brands - these are super sturdy and well made. Etrailer comes through again with a great product and fast delivery. Great company - love the installation videos!
I installed the Bearing Buddys and ran them for 100 miles or so before going on a 500 mile trip. On the first 50 miles on the highway one of the Bearing Buddys flew off and I lost it. The hub was no warmer than the other side and I was driving under 65mph in 60 degree heat. I also have new tires and bearings. The Bearing Buddy’s were very snug so I don’t know why they came off. I have used Bearing Buddys in the past with no problems, but now I feel like I need to carry a spare pair or at least one spare just in case.
Installed on a Harbor Freight trailer. Very straightforward. Took about 20mins per wheel, including jacking & clean-up. No issues at all. The Bearing Buddies have remained well sealed and have maintained grease pressure on the hub bearings. Did exactly what I'd hoped and has given me increased confidence in towing longer distances.
Shipping was a little strange as it sit in Indianapolis for 4 days but HEY that has nothing to do with etrailer. The 2047 etrailer Bearing Buddies worked prefect and I can already tell they are going to last a long time for my trailer. A+++
