Bearing Buddy 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" and reveals a blue auto-check ring so you know it's full.


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, revealing a blue ring. This prevents overfilling that can damage the inner seal.


You can manually check the grease level in your Bearing Buddy by checking the blue auto-check ring. If it has receded flush with the steel retaining ring, more grease is needed. If you can see the blue ring, the hub is properly filled.

Video Transcript for Feature Review Bearing Buddy Bearing Protectors-BB27SR

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the Bearing Buddy stainless steel bearing protectors for the 2.717 hub bore and it is for a quantity of two. Now these are great for marine applications. The Bearing Buddy design is an easy way to protect your bearings by keeping water out and ensuring enough grease is in the hub. These do replace your refactory grease caps that are on your axle hub and provide your trailer bearings with premium protection. Basically these will prevent wheel bearing failure by providing an easy way to control the grease volume in your axle hub.

And it does allow boat trailer wheels to be completely submerged. Does help stop corrosion and pitting on the bearings. If you notice right here, it provides a easily accessible grease zerk fitting, makes adding grease to the bearings very quick and simple. Basically, when they're installed with the cover on, you just pop the cover off, you see the zerk fitting, attach your grease gun and pump the grease in. It does maintain a slide control pressure about 3 PSI with the spring loaded piston, prevents water from entering the hub and with this blue ring right here, it does allow visual monitoring of the grease levels using that blue indicator ring.

Basically that ring will sit flush with the top of the cylinder when it's full. And if the ring that goes below the top, you just add pumping some more grease to move the piston outward. This does prevent overfilling and rear seal damage with the automatic pressure relief feature. Basically the grease will seep around the piston edges and into the barrel when it's full. As we mentioned, these are constructed of stainless steel, so they do ensure longer lasting fit than your plastic or aluminum products that are out there.

And it does come with the rubber protective covers that you just, once you fill it with grease, just put the covers over it and it keeps anything from getting into there. And these do install easily by putting on the hub. Basically you take out your off your grease cap, put these on the hub, put a block of wood on top of 'em, and then use a hammer and tap against it so the Bearing Buddy installs evenly all the way around. These parts are made in the USA. Few specs, again, they are designed to fit the 2.717 hub bore diameter.

Now these also come available in other diameters to fit your hub size. This part here works with the outer bearing model numbers 14124 and 14125A, which are commonly found on the 5,200 pound to 7,000 pound Dexter axles. But that should do it for the review on the Bearing Buddy stainless steel bearing protectors for the 2.717 hub bore.

I haven't move the trailer after I put the BB1980T-SS grease cap on it. They started on pretty good then got harder about mid way on, so I got a pipe ranch to get them all the way on but over all it wasn't very hard to do it only took about 15 minutes to complete the project which is good. They really set the trailer off because the trailer is painted Black.



by:

Item shipped fast and secure. I always receive the correct part when I order. Thank you



by:

After being unable to get replacement Bearing Buddy's from my local boat dealer, (they claimed they were on order for 3 months) I finally got smart and found etrailer online. Easy ordering process and I had my new Bearing Buddys in less than a week. Great service, great product, I'll be back for all my trailer parts and accessory needs.



by:

Love how easy it is to keep the wheel bearings greased with these Bearing Buddy's.
Just pop the cover off, hook up the grease gun, a few quick pumps, and the bearings are ready for another season. The blue inside plate moves out as the grease goes in so you do not over fill the bearing. Slid the cover back on and you are done.



by:

As expected, fast shipping



by:

Service and shipping second to none!Thanks again!



by:

Great quality bearing enhancement. Keeps your hubs clean from dirt and packed with the right amount of grease



by:

Quick shipping, work great !



by:

Great Product and was the perfect fit for my trailer. Fast shipping and great service!



by:

wrong shipping address was applied to the order attempted two minutes after placing the order to change the address. All I got was voicemail basically two days later I received a response saying it was too late and of course, after two days, it would be too late.



by:

Fast shipping on these bearing buddys. They are an odd size, it was an old international truck axle I used to build a trailer. I couldn't find them anywhere else, and the price was good for a quality bearing protector.



by:

I replaced my plastic hub cap that fell off with these. The stainless steel models are extremely high quality. Very pleased with the purchase. After pounding them on my new hubs, I don't know how I can remove them to service the bearings in the future. Hopefully I won't have to take them off.



by:

Installation instructions were very helpful and thanks to the customer service rep, these fit my hub assembly perfectly.



by:

I lost one of four bearing buddies. I love these things, I just wish they made a model that could be used with greasable spindles. Now to figure out why the first one came off my brand new trailer. I used red picture on this one, we will see.



by:

Perfect for my trailer and will help seal out water and hopefully add life to my bearings. etrailer is and always will be my stop for great products and service!



by:

Really only needed a cap. Because not a boating trailer. But 1.81 diameter in dust caps is hard to find. It fits good. Etrailer is the place, when it comes to a large size variety.



by:

Delivered right on time fast shipping great products!



by:

Bearing Buddies customer support is horrible, one of my new caps was defective the grease zerk came off, I contacted them and this is what they sent me, I guess I’m supposed to bring it to a mechanic and pay $$$ to have it fixed ! Garbage !



by:

All 3 products are working well. Before the new parts, the trailer blew a tire which bent up the fender and smashed a tail light. I ordered what I needed from eTrailer and put my trailer back together. Parts were all available and came quick. I didn't miss any fishing opportunities as a result.



by:

Great price, excellent quality, delivery was fast and installation was easy, the bearing buddies arrived today they are on the trailer and ready to go.
Thanks e trailer!



by:

Product Review: Only intimidating before you install. Really easy, pop out the OEM caps and replace with the bearing buddies, fill the buddies with your grease gun and you are done. Nice to know my (well greased by the factory ) wheel bearings now have a supply of grease under slight pressure to be sure there will always be grease in my bearings and foreign matter will be kept out.

See what our Experts say about this Bearing Buddy Trailer Bearings Races Seals Caps

  • Roadmaster Comfort Ride Leaf Spring Suspension Kit for CrossRoads Elevation TF3612
    Hello again Adam! Since you have 7k Lippert axles the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 is the correct kit. This is going to be a significant improvement over the stock suspension. For wet bolts you can use the # 34007-187-00. With the way the system works you will only need four wet bolts for this setup. Let me know if you need anything else!

  • Is There Bearing Buddy that Fits 2024 Kara SPE Sea Doo Switch Trailer
    Hey Darin, we probably do have a Bearing Buddy kit that fits your Seadoo Switch trailer but I would need you to remove your current grease cap and measure the bore where the cap installs and get me that dimension. With that I would be able to tell which you'd need. Unlike vehicles trailer replacement parts aren't as well documented so I can't just look up your trailer. The part # BB27SR that you referenced would be correct if that dimension is 2.717 inches.

  • Can a Bearing Buddy Bearing Protector Be Used On a 7,000LB Lippert Axle With EZ Lube Grease Zerk
    With your 7,000LB Lippert axles already having a zerk fitting on the end they are designed to use the Grease Cap # TRU66FR to easily access the grease zerk. While the Bearing Buddy Bearing Protectors 1.98" # BB1980A are to small for your hub we do have the 2.717" # BB27SR for your hub size. This will generally require you to remove the grease zerk from the end of your spindle to use.
