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.

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:

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

Have had no problems with buddy bearings they work great and give me confidence when making long hauls.



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:

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:

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.

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:

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:

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:

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



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:

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

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!

Still working like a charm. No complaints.

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:

Ordered the Bearing Buddy Bearing Protectors. They were delivered promptly and fit perfectly.



by:

THE RIGHT PARTS CAME AND THEY GOT HERE IN THEIR SCEDULED TIME. THEY WERE ALSO DELIVERED QUICKLY ENOUGH FOR ME TO ORDER OUT NEXT TRAILER PARTS FROM YOU
THANK YOU



by:

On our toy hauler-work perfect. Do not have to remove the wheel bearing as often



by:

Great product! Easy to install! Keeps your bearings greased, and you can tell when it's time to add more, simply.



by:

The parts I recieved were in good condition considering the box they came in was trashed. Two of the bearings were a little bigger than the other, they took a little longer to install. One I hope I didn't damage having to hit it a little harder. Overall if they all work I will be very satified.



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.



by:

Bearing buddy are the best
Easy to
install easy to use
Have them on all of our trailers



by:

Page easy to negotiate, found a whole bunch of other things there too... Later.
Exactly the product I ordered.
Fast delivery.
Haven't put them on yet so I have no idea if I will need customer service but the note in the box says they will be there.
Directions good and simple.
thanks

Everything looks like what I ordered. I was impressed with the sales person I talked to and that it was shipped the same day. Thank You

  • Precision Digital Caliper to Measure Hub Bore to Select Correct Bearing Buddy Bearing Protector
    Bearing Buddy protectors are made in lots of sizes, many of which are very close to one another in their diameter. It is really necessary to use a more precise measuring device on the hub's bore unless you know the part number of the one that was lost. You might check the remaining one for any identification. There are two sizes that are close to your 2-9/16-inch dimension, 2.562-inches and 2.717-inches. Bearing Buddy parts that fit hub bore diameter 2.562-inches are either part # BB2562SS...

  • 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.

  • 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.

For the Dexter Trailer Hub and Drum Assembly for 5,200-lb to 7,000-lb Axles - 12" - 8 on 6-1/2 # 8-219-4UC3 you were looking at you will need the # K7CAP if your spindles have the grease zerk built in. The removeable rubber plug allows you to access this zerk without needing to completely remove the cap. If your spindle does not have a built in grease zerk you will need to go with the Bearing Buddy Bearing Protectors - Model 2717 - Chrome Plated (Pair) # BB2717 instead. These...

  • 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.

  • Replacement Bearings and Seals for Converting 8K Oil Bath Dexter Axle to Grease
    I believe I was able to find the bearings and seals that you need, but you'll want to double check on your end by removing the hub and looking at part numbers just to make sure. Inner Bearing - # 25580 Inner Race - # 25520 Outer Bearing - # 02475 Outer Race - # 02420 Grease Seals - # RG06-070 (2.250" ID and 3.376" OD) When it comes to the oil bath caps from what I could find yours should be part # RG04-230 which has an OD of 2.875" and nothing we have is that fits that.

  • 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 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.

  • 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.

  • Is Grease Seal Removed to Install the Bearing Buddy Kit on Trailer Hub
    The only thing you'll be removing to install the Bearing Buddy # BB2717 is the grease cap on your hub. There should only be an inner seal for your hub and the grease cap or the Bearing Buddy will be the equivalent of an "outer" seal.

  • 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...

  • Recommended Hydraulic Brake Assemblies, Actuator, And Brake Lines For Dual Axle RV
    For your conversion to hydraulic brakes on your 7,000 lb dual axle RV, I recommend the Hydraulic Brake Kit - Uni-Servo - Free Backing - 12" - Left/Right Hand Assemblies - 5.5K to 7K # AKFBBRK-7. These assemblies are side specific and are labeled for you. These will work with your current hub and drum assemblies. For installation and adjustment, you will want the Brake Adjustment Spoon for Drum Brakes # W80630. If you need the mounting bolts for these assemblies, I recommend # BRKH12. If...

  • Selecting Correct Bearing Buddy for 8-Lug Hub on 7000-lb Axle on PJ Dump Trailer
    Selecting the correct Bearing Buddy bearing protector for your 8-lug hubs requires that you know the hub's bore where the grease cap (or Bearing Buddy) fits. This requires using a precision digital or dial caliper and measurement to the nearest thousandth - 3 decimal points. You also want to note whether you hubs are threaded or non-threaded as we offer both types of Bearing Buddy. For example, we offer an 8-lug hub for 7K axles, part # 8-219-4UC3, and this hub's bore happens to be 2.720-inches...

  • 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 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.

  • 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.

  • 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.

  • Will Bearing Buddy # BB2717 Work With AL-KO 7,000-Lb Axle
    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.

  • How to Determine Correct Bearing Buddy for 2011 Newmar Kountry Star 5th Wheel Trailer
    In order to determine the correct bearing buddy for your 2011 Newmar Kountry Star 5th Wheel, you will need to locate the outer bearing number or take a precise measurement of the hub bore using a digital caliper like # PTW80157. This will ensure you will find the correct buddy bearing. For example, the Bearing Buddy Bearing Protectors # BB2717 fit a 2.717 inch hub bore and works with outer bearing models 14124 and 14125A. It is commonly used with 5,200 - 7,000 pound Dexter Axles, which...

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...

  • 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...

    The largest Bearing Buddy available is a 2.717 inch diameter # BB2717SS (stainless steel) or # BB2717 (chrome plated), which means you wouldn't be able to convert your oil bath hubs to greased ones. However, we do carry the direct replacement for your Dexter Oil Cap Kit number K71-148-00, the Redline # RG04-270, which includes the cap, gasket and plug and is designed for 9K-15K Dexter Oil Bath Hubs like # K08-288-90.
