Protect your trailer bearings from water, dirt, and corrosion while making greasing quick and easy. Bearing Buddies maintain light grease pressure inside the hub to help prevent bearing failure, even when your hubs are completely submerged.
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.

This product is just great. I've used these on my other trailers and I swear by them. They stay in place under very rough conditions and do a fine job of keeping the bearings greased.
They fit perfect. Took a 5000 mile trip this summer and was glad I had the option of applying grease to the bearings.
Great product, Good company and super fast shipping

Perfectly! Can’t go wrong with bearing buddy
Haven't put it on yet,but the service and the tome it took to get it was excellent. Went to the dealer to get a buddy bearing they were all you need the Vin number of your trailer and what kind of axle it has,went Google Drive it and 3 minutes later had it ordered 6 days later I had it.
I put 4 of these on my 26' fifth wheel. The installation was very easy and exactly as described. I tapped them gently with a hammer to get them started and then used a block of wood and hammer to seat them fully for a nice tight fit.
I've been using Bearing Buddies on my boat trailers since the early 80's and never had a trailer bearing fail. These are still the best solution to protect any bearings that get submerged. Make sure they are pumped up before each submergence and everything will last forever.
Bearing Buddies are worth the investment. Saves time on maintenance and money on parts (and labor if you farm out the work). I've used these on flatbeds, cheap Harbor Freight trailers, utility trailers and now finally putting them on my toy hauler. Quality piece and is US Made. The ONLY suggestions is verify your hub size and if you measure it and still doubt what you measured ask etrailers wonderful customer service. there are a lot of different hub sizes.

I work as a fisheries biologist for a state agency and travel hundreds of miles every week with my boat. These bearing buddies and other bearing products have worked great and were a huge upgrade over other trailer hub products I've had in the past. So far no issues.
The product and the service was exceptional. The Buddy Bearings fit exactly and were easy to install. The items arrived in a few days through the US mal without any problems. It was really nice to be able to track my order so I'd know when it was arriving. I will be ordering any additional items needed from etrailer.com because they actually had the best price I could find.
Great for, I didn’t realize I had the ez lube axles and didn’t need these. I really like the covers better than the cheaper ones. I removed the inner zero assembly so I can use these as caps. Much thicker material and better looking.
Work great, have absolutely no problems with these bearing caps. Work much better than the etrailer brand caps I ordered at the exact same time for my other trailer.
Worked out great and quickly delivered.
Purchased for my Utility trailer, fast shipping , perfect fit , great selection , have purchased fenders etc from etrailer before very happy with all my purchases
Putting off greasing wheel bearings is so easy to do. Bearing Buddies make greasing wheel bearings easy because they give incentive. Only takes 5 minutes vs a couple of hours. Being on the side of the road with a break down from bad bearings isn't fun and totally preventable.
they came in the mail when you said they would. they were exactly what i wanted, and they fit perfectly. you people know what you are doing. if i need anything else that etrailer sells, i will surely order it from you

the protectors are fine, but the rubber covers have disappeared. i pushed all the air from them when i put them on. do you sell them seperately? other than that i am happy with them. thanks wayne

I recently upgraded to electric over hydraulic disk brakes from the hydraulic drum surge brakes that were on my boat trailer when I bought it. I scoured the web site and put together a list of parts for the conversion but still had a few questions. Lisa was most helpful and had some additional suggestions. She made my etrailer.com shopping experience the best online shopping experience ever. Once I had the brake parts I found my old Bearing Buddies didn't fit the new hubs so I ordered new Bearing Buddies and new coupler while I was at it. I ordered them on Sat. and they arrived today, Tuesday. I already have the new parts on and they are working perfectly. Thanks etrailer.com and thanks Lisa. You have a new customer for life.
Nice item and very easy to install, trouble free traveling.
These are the BEST hands down! The originals, a must have if you want to keep your axles in optimum dependability. Easy to install, easy to service, and peace of mine knowing the bearings are greased. Great customer service and knowlageable help with getting the correct size.
While we only just received out bearing buddies. They are as described and installed easily. The only trouble was the beauty covers don't fit over the hubs any longer. Doesn't really matter as the product is attractive. The wheel studs not so much but we can live with that.
I will have to write another review after we have taken a few trips and greased things up a bit.
Quality product,
Great product and excellent customer service! Thanks, etrailer.

You're very welcome John, I'm glad we could help!!
This product is as good as their rep have used them before on a
boat trailer never had a bearing go out as long as I used the
buddy bearings they are great! Service was just as good.
These bearings were installed on a heavy duty low boy trailer.
No pictures trailer is in South Texas about 300 miles from my location. Hauling oil field equipment. Picture of the trailer being
overhauled before new fenders were added.
Your product arrived on time and undamaged. It installed exactly as described in the literature. I am very pleased with my new Bearing Buddy's. As a side note I noticed a small amount of chrome machining debris inside the hub of the housings. It was easily cleaned out with a rag before installation. These Bearing Buddy's are installed on a 32 year old utility trailer I am refurbishing. Although the trailer is small (4 x 8) it has a 5000# axle and has seen some pretty tough use. Ive attached a pic of the trailer undergoing refurbishment along with a couple of pics of the installed Bearing Buddy's. Excellent product and service!
Great customer service and shipped fast.
Ordered these for my 5th wheel trailer 8 days before vacation. They were shipped and received with 3 days to spare. Installation was flawless. Thanks etrailer. Well done!

Just started our camping season. Pulled the caps off, hooked up the grease gun, pumped some grease and done. Took longer to write this then grease. No pulling the 4 tires to get to the bearings and getting my hands greasy.
Info for this part was:

Still working a year later however a side note. Do not over grease as it will leak onto the inside of the drum and prevent the brakes from grabbing.
