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.

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!


Comments
part number BB2047 will fit the following Harbor Freight Trailers.. 90154, 42709, 90153.42708, 2575 and 2948, as all those trailers use the same Harbor Freight replacement dust cover, received mine and they installed with little effort great product..Thanks etrailer,com

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 this product

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

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.

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!

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.

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.

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.

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.

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.

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.


Comments
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.

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!

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+++

etrailer.com had the exact item I needed when my local trailer place boldly proclaimed, "It doesn't exist." I needed grease caps or Buddy Bearings for an odd size brake drum (3,500# axles). They were brand new, bought off of ebay. Opening measured 2.0345 and standard is 1.98 or 2.38/2.44. It took me a while but eventually I found that etrailer had exactly what I needed -- 2.047 Buddy Bearings. I researched the part number for price and with shipping etrailer was several dollars cheaper than anyone else. Others had commented that they had used them for exactly the same purpose so I took a chance. Shipping was quick and they arrived in perfect condition. I stuck them in the freezer until the next morning (to get as much "shrink" as I could) and then drove them in with a block of wood and my trusty hammer. Snug but good fit. End of story.

  • 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.
