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.

The blue indicator ring allows you to visually monitor the amount of grease in your hub. The ring should sit flush with the top of the cylinder. If the ring is below the top of the cylinder, add grease until the piston moves 1/8" outward.

I installed these without too much difficulty - the etrailer instruction video for bearing protectors was extremely helpful. I haven't used the trailer much yet but expect these to work well.


First rate service and product knowledge.





I was struggling to find the correct hub kit for my boat trailer because etrailer has a large inventory of products. I decided to call and the salesperson Mellissa found the correct part in minutes and had it shipped to my house in less than 24 hours. It’s is nice to know that etrailer still believes in great customer service and the human element of customer service.


I recently upgraded my 43 year old small boat trailer with parts from ETRAILER. New hubs, bearings, Bearing Buddy's, wheels and tires. Natalie L spent quite a bit of time on the phone with me to figure out what I needed and when it arrived everything was perfect. This is the first time I have replaced the hubs and wheels in 43 years. Timely service, great prices and I could not be more pleased.


Bearing Buddies, the only way to fly on a boat trailer. No substitutes.


I could not be happier,

What a
diiference to have not just good brakes, but great brakes. Plus, the install was so easy, all the hardware was a perfect fit, instructions were right on the money (btw, I'm a retired engineer from a nuclear plant and I wrote procedures, so I'm picky) Anyway, towed the boat 1,000 miles and what a reassuring feeling to know that the equipment is in good working order and does the job when called upon.

I'm attaching a couple of pictures so you can see what I did.

Thanks again, I will be using etrailer in the future anytime I need something, feel free to pass on my comments


Works great, no issues. Another happy c amper!


Buddy bearings make keep grease in the hubs so much easier. No need to take them off to apply grease, just shoot some marine grease into the zerk fittings and put the soft cap back on and your good to go. Easy to install!


When I called etrailer for supplies I spoke with Dana. She was most helpful in securing the correct bearings and races for my small trailer. She helped through the entire process and had my order shipped the same day. I am very satisfied with the order and the speed it was delivered. I am sure you will be happy with any order placed with etrailer, Chuck B.


Easy and fast as always!! Thank you!


Very snug fit with the new etrailer blue dot hubs , went on nicely, abit of hitting with a dead blow hammer but nothing to excessive, they do not feel like they will be lost going to the ramp, possibly the galvanized hubs help with the good fit, just got to head out to the ramp to see, feeling confident.


Installed with ease and seem to be doing what they are intended for well.

Thanks eTrailer!



All has been great!


I fitted these to my Northern Tool 4x8 folding trailer, so I don't have to worry about repacking the bearing anymore. They are excellent quality, and I highly recommend them.


I didn’t realize that there were a pair in a package. But the tech is great.


super customer service! I lost a red eye bearing cover when I hit a boulder in the road. I had recently installed a complete 2 axle disc brake kit with coupler for my boat trailer that I ordered from etrailer. Mike S. found the right size from my original order and shipped out new Bearing Buddies in no time flat! I highly recommend etrailer to everyone I know.



no complaints


Delivered a month earlier than expected. They were installed on the trailer 10 minutes later. You guys are the best


Quality parts and perfect fit.


Look, there are various bearing buddy knock offs out there that might be "good enough". These are the real deal and they have added a nice little feature - these blue ring indicators. The indicator ring lets you know when you might need to add more grease - and might also keep you from going overboard. I think it is more common for people to try to push too much grease into the hub especially with bearing buddy protectors installed.
Great insurance for a boat trailer especially.



The bearing buddies still look great one year later. As fishing season starts again in mn I look forward to being able to check at a glance to see whether I need to add grease.


Good service!!!


1 problem, I found out after I ordered, the price was 12.00$ higher than others. I think you should price match on items such these. thanks kenneth barry estey


Attached are two photos of Bearing Buddy protectors on my Time Out tent camper.


Bearing Buddy protectors live up to their reputation. What I really appreciate is the immediate attention and prompt shipping etrailer gives to each order. Thank you etrailer!


Great company, service & products at competitive prices. Reasonably priced Shipping as well!


Did not use as hubs were wrong


I installed bearing buddies on a boat trailer that sees both fresh water and salt water. In the past, despite loading the bearings up on grease, it wasn't uncommon to replace them every couple of years. We are at the year one mark with the bearing buddies and no issues. Also, the bearing buddies also show you how much grease is in the wheel hub; our hubs only needed a small amount of grease to top them off the beginning of this season.
