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.

I've been pleased with how nice the bearing buddies are holding up. They still look nice, after a year. I would recommend ETrailer to anyone, they have great customer service.




by:

Fast Service, got all the correct parts as promised!




by:

Liked these until the 4th and last one I removed to tighten the nut. Wasn't too happy with this one. I thought they would be one piece. Took a large pair of water pump pliers and a crowbar to get the insert out. Needless to say I had to order a replacement. I'd have given it 4 stars until this.




by:

Worked as described.

Work great. Used on my 2001 horse trailer. Very easy to use
Carlos - 01/14/2022


by:

EXACTLY what I NEEDED for my trailer! First I went to the local Auto parts store, the first question they asked 'What is the make and model of your car". I should of know better. First question from etrailer... how many do you want! THANKS etrailer you are the best source for my trailer parts. ALSO It was delivered on time!




by:

Ordered the Bearing Buddy Bearing Protectors. They were delivered promptly and fit perfectly. They also included a note in the order stating that if they didn't fit, just send them back and they'd work to find something to fit. This company seems to care a lot about customer satisfaction.




by:

I ordered to pairs of these Bearing Buddies for my horse trailer. They fit perfectly and are of very high quality! I was very impressed with how quickly I received my order also! I ordered them about 5pm on Monday and already received them in Wisconsin on Wednesday!!! Thank you, etrailer! I was also very impressed with the great price I got them for!




by:

got large bearing buddys for a large axle trailer that i could not find anywhere.
i inadvertently made 2 orders because the first order i ordered only 1 pair, letting the fact the trailer had 2 axles. therefore i placed a second order exactly as the first. later the same afternoon i got a call asking to confirm 1 or 2 were needed. they thought i may have accidentally ordered the same thing twice. NO, i confirmed it was my error in ordering only 1 pair and that i actually did need 2 pair. confirmed, they processed the order and shortly thereafter within their promised time i had them. exactly what i needed and QUICK!




by:

I put these on my 22ft stock trailer.Easy to install, easy to fill with grease. Way better than packing the bearings every couple of years. Ill put these on all of my trailers.




by:

Came as advertised.




by:

Ordered two boxes of bearing buddys for a great price and I selected two-day shipping. Ordered was processed and shipped right away, however UPS dropped the ball. I notified customer service and they issued me credit for the difference in shipping. The parts I ordered showed up a couple of days later. Will definitely be doing more business with etrailer in the future.




by:

Had to machine slightly to fit my drums. Very happy with products and service.




by:

We are going to reserve our opinion because our experience with bearing buddies has literally cost us thousands in repairs due to their failure to stay on for more than 5-10 thousand miles.

It may work fine for those doing a few hundred miles a year.

I have a tandem trailer with brakes only on the rear, I decided to add brakes to front axle. Parts bolted on easy, and worked great. No fitment issues.




by:

Cristy knows the products well and quickly found the right Buddy Bearings for my trailer. They arrived in a timely manner and fit perfectly. I will recommend etrailer to all my friends. Cheers, George

Fit great and worked as descibed. Good detailed installation instructions.

by:

Only company I could find that had these to fit my 7000lb axles. Installed easily and work great. They give a great peace of mind knowing there is grease in the bearing.




by:

Delivered in timely manner. For most part it is a good product. But make sure the nut that hold grease fitting are tight before you put it on.




by:

The bearing buddy that I ordered were a great buy and were easy to install , Will save me a lot of time not having to take apart to grease the bearings. Thanks for a great product




by:

The Bearing Buddys were just what I had been looking for. I could not find them in the size I needed on a store shelf. Thanks for the quick service.

  • How to Measure for Selection of the Correct Bearing Buddy Bearing Protectors
    There are two ways to measure to determine the correct size of Bearing Buddy Bearing Protectors you will need. The First way is to measure the outside diameter of the bearing cap installation surface. If the bearing caps are removed gently without deforming them then this is the easiest way to measure. You will need to use a Dial Caliper to take these fairly precise measurements. The other method of measuring also requires the use of a dial caliper. You will need to measure the inside...

  • Bearing Buddy Compatibility with Dexter 6000 lb Axle
    I'm assuming there is a typo in the ID you gave. Based on the Dexter 6K hubs, it appears you may have a 2.72 grease cap. That is the closest I found to the size you gave. The Bearing Buddy Bearing Protectors - Model 2717 - Chrome Plated (Pair) # BB2717 would be the fit for that model. If you can give me the numbers on your hub, I may be able to pin point the correct kit for you if there is one.

  • How To Measure For Bearing Buddies On Trailmaster 20 Foot Trailer
    It sounds like the Bearing Buddy Bearing Protectors - Model 2717 - Chrome Plated (Pair) part # BB2717 are what you need for your hubs. These bearing buddies fits a 2.717" hub bore which sounds like what you have but I suggest measuring the inner diameter of your hub bore with digital calipers just to be sure because it sounds like you may have measured the outside. To get 4 of these bearing buddies you would simply need to purchase 2 of the part number BB2717. If your measurement ends...

  • Can Bearing Buddy Bearing Protectors Be Used on EZ Lube Trailer Spindles
    You can indeed use Bearing Buddy Bearing Protectors on the EZ Lube spindles for your trailer but as you mentioned you will first need to cut off the zerk fittings. The zerk fitting would prevent a proper fit but once it's removed you're good to go. If you are blowing seals though with the E-Z Lube spindles I would first check to make sure you aren't over filling the hubs with grease. Using a double lip grease seal will also help this. The Bearing Buddy Bearing Protectors # BB2717 that...

  • How to Remove Bearing Buddy Bearing Protector From Hub
    The best way to remove a Bearing Buddy Bearing Protector like # BB2717 is pretty much what you've been doing. Because the fit inside the hub bore is pretty tight, you just have to take a rubber mallet (or wood block) and firmly tap it around the sides until it's unseated and loosened up enough to pull it out by hand. This process is briefly shown right at the beginning of the video I attached below. If your Bearing Buddy came out in a couple of pieces it was likely damaged in the removal...

  • Are the Bearing Buddy Bearing Protectors BB2717 Threaded
    The Bearing Buddy Bearing Protectors part # BB2717 are not threaded, they instead offer press-in installation. There are Bearing Buddy Bearing Protectors available which are threaded but not for a 2.717" bore. I have attached a full list of options below but you will need to verify the exact hub bore down to the thousandth of an inch to confirm.

  • What is the Reaction When Two Greases Aren't Compatible?
    It is true that some greases do not play well together but this is based on type of grease and not on brand name. When incompatible greases are mixed, the different thickener types with cause the mixture to harden and not release any oil or do the exact opposite and soften too much so all the oil releases. Either can obviously cause bearings to fail quickly. I've attached a chart to assist and have also linked an article to further addess the different kinds of grease.

  • Bearing Buddy Bearing Protector Function and Initial Installation
    The Bearing Buddy bearing protectors like # BB2717 have the integrated grease zerk and a spring loaded piston that provides 3 psi controlled pressure to keep grease in the hub and keep water out. It is designed to pack grease throughout your hub as you stated keeping the bearings coated. It will require far more than you previously used as it will fill the space between the bearings as you stated but it will keep maintenance to a minimum as it keep everything well lubricated and keeps...

  • Bearing Buddy Protectors for 7,000-lb Dexter axles
    Thank you very much for your follow up question. The Bearing Buddy Bearing Protectors # BB2717 are designed to work with outer bearing model 14125A and outer bearing cup (race) model 14276, which are commonly found on 7,000-lb Dexter axles. Most grease caps on 7K axles have a flange diameter of 2.722 because they are made of very thin metal and are designed to slightly crush when they are pressed into the hub bore. The Bearing Buddies don't crush as easily so they are made closer to spec...

  • How Does Inner Bearing Get Grease When using Bearing Buddy
    Bearing Buddy pumps grease into the center of the hub all the way back to the grease seal. A double lip seal should be used to prevent grease from blowing out the seal when added. When the hub and seals and bearings are first assembled, they should be packed. After a period of time and when you want to maintain the grease on the bearings, the grease would travel from the zerk fitting on the Bearing buddy through the outer bearing. It would then fill the cavity inside the hub and continue...

  • Bearing Buddy for Trailer Hub that Has Bearing Number of 25580
    Since you didn't specify which bearing of your hub is 25580 I am fairly certain that the correct Bearing Buddy you would need would be the part # BB2717. But you will need to measure the bore where you old grease cap sits currently to verify that it is 2.71 inches in diameter.

  • Does Zerk Fitting On EZ Lube Spindle Need To Be Removed When Using Bearing Buddy?
    Since your Carry-On Trailer has EZ Lube spindles with a zerk fitting you will need to go ahead and remove the zerk fitting to allow the Bearing Buddy Bearing Protector # BB2717 to send grease to the bearings and spindle. I included a video of the # BB2717 for you to take a look at.

  • Correct Bearing Buddy Bearing Protectors for 7K Axle with 14125A Outer Bearing

  • Can Inner Bearing be Reached with Grease Using Bearing Buddy
    Bearing Buddies aren't ideal for getting grease through the outer bearing to the inner bearing. Typically the amount of pressure required to get the grease that far would end up eventually blowing out the seal or pushing off the Bearing Buddy. It's best to grease the bearings by hand to prevent that.

  • Bearing Buddies for a 6,000 Pound Dexter Axle with 8 Lug Hub
    Check the outer bearing and race numbers stamped into the metal of the bearing and race in the hub. Most 6,000 pound 8 lug wheels we carry use outer bearing # 14125A if it is an 8 on 6-1/2 bolt pattern. If it is an 8 on 8 bolt pattern, it may use # 506849 outer bearing. If you have the 14125A outer bearing, you can use Bearing Buddy Bearing Protectors, # BB2717SS, or # BB2717.

  • Bearing Buddy That Fits 2.7 Inch Hub Bore
    We do have a Bearing Buddy which fits a similar dimension as the 2-3/4" you referenced but I do recommend using a digital caliper and measuring your hub bore size to the thousandths of an inch to ensure you get the correct fit. For a 2-3/4" hub bore the closest fit we have are Bearing Buddies that fit a 2.717" hub bore, the Bearing Buddy Bearing Protectors - Model 2717SS - Stainless Steel # BB2717SS and the Bearing Buddy Bearing Protectors - Model 2717 - Chrome Plated # BB2717.

  • Recommended Bearing Buddy Bearing Protectors For Hub With 2.567" Grease Caps
    It sure will! Since your current grease caps measure 2.567" the correct Bearing Buddy Bearing Protectors for your hub will be the # BB2562 which measure 2.562". This is close enough in size that it will work just fine. I included a video of the # BB2562 for you to take a look at.

  • How Far to Tap Bearing Buddies into Trailer Hub
    You'd want to the Bearing Buddy part # BB2717SS as far as you can into the hub as that will allow them to fit as securely as possible. So you'd want to go past the ridge you mentioned.

  • Should Bearing Buddy System Replace Sure Lube Hub Setup on Trailer
    By Sure Lube you mean like an EZ Lube setup that has zerk fittings on the ends of the spindles to grease through the middle of the hub? That's what I was able to find when Googling your setup. If so, you can install a Bearing Buddy over this style of hub but it's typically better to stick with the EZ Lube setup as it applies grease in a way that's easier to reach the bearings. If you can get me the diameter of your hub where the grease cap fits I can get you a cap with a removable center...

    You will want to use a digital caliper like part # PTW80157 to measure the inside dimension of your hub to make sure you get the correct Bearing Buddy. The Bearing Buddy Bearing Protectors, part # BB2717 are designed to fit a hub bore that is 2.717 inches diameter. If your outer bearing is a # 14125A, then the # BB2717 would work for you.

  • Bearing Buddy Bearing Protector for 7,000 Pound Trailer Axle
    The most common hub bore diameter for 7,000 pound trailer hubs is 2.717", for which the Bearing Buddy Bearing Protectors # BB2717 will work perfectly. With that being said I still highly recommend verifying your existing hub bore diameter with a digital caliper like # 301-17068 to be certain, as not all 7,000 pound hubs are created equal. I have attached a short video review on this set that you can check out as well.
