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.

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.

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. New World LLC

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!

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.

Ask the Experts about this Bearing Buddy Trailer Bearings Races Seals Caps

  • 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.

  • 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.

  • 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.

  • 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.

    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...

  • 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 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 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...

  • Which Bearing Buddies Will Fit a 2-7/16 Inch Hub Bore
    You will likely need 2441 model Bearing Buddies: # BB2441 for chrome or # BB2441SS for stainless steel. Your hub bore will be slightly less than this if it is exactly 2-7/16 inches and that ensures a tight fit. The hub bore should really be measured using calipers such as # PTW80157 because the measurement has to be as accurate as possible.

  • Does Zerk Fitting On EZ Lube Spindle Need To Be Removed When Using Bearing Buddy?

  • 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.
