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.

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.

Received all the items I ordered today so I was able replace 4 bearings and races, two seals, and Bearing Buddies on my boat trailer. Everything went perfectly, especially as this is the first time I've done one of these. The new Bearing Buddy looks to be much better than the old ones. One of the old ones had been damaged inside because the installer had left the cotter pin too long, and it tore out the zerk, letting water in and destroying the bearings. Thanks for prompt shipping and a complete and well packaged order. 837927

  • Recommended Bearing Buddy and Bearing Kit for Malone MicroSport Trailer
    The Malone MicroSport Trailer # MPG460G does have the 1.98 inch inner diameter hub. I confirmed this with the manufacturer. To add bearing buddies, you simply need the # BB1980A for chrome or # BB1980A-SS for stainless steel. You will not need to replace the bearings to install these caps. You can simply use the LubriMatic Economy Size Mini Grease Gun # L30100 and add the marine trailer wheel bearing grease # L11399 that matches what the axle comes with. When installing these, you...

  • How to Monitor Grease in Hub With Bearing Buddies
    These are good questions so I will answer them in the order you asked. 1) When using Bearing Buddies the inspection will be done depending on which model you use. For Bearing Buddy Bearing Protectors - Model 1980A w/ Auto Check # BB1980A there is a blue indicator ring which will gives you a visual indicator of the amount of grease in your hub; this ring needs to be flush with the top of the cylinder. If it is under the cylinder you simply need to add grease until the piston is 1/8" outward....

  • How to Pick Out Correct Size Bearing Buddy
    To find the correct size Bearing Buddy for your log splitter, you need to measure your hub bore diameter. I have attached a photo to show you where to take this measurement. A digital caliper like # PTW80157, will provide the most accurate measurement. Bearing protectors like # BB1980A, take the place of a regular grease cap. Since grease caps can easily bend/deform when being removed, measuring the actual hub bore on which they fit is what's recommended. For example, Bearing Buddy...

  • Red Grease for Trailmaster Trailer Hubs
    Red bearing grease is a very common grease used in trailer hubs which for that we have the Lubrimatic LMX Red part # L11390 which is Lithium based. This is the same as what you have now and since it's considered to be the best grease for trailer hub applications it's your best choice.

  • If Grease is Gritty in Bearing Buddy Should Bearing Buddy Be Replaced
    If there is possible metal shavings or dirt inside the Bearing Buddy the best recommendation I can make is to replace what you have so that you don't end up missing something small while cleaning that would end up damaging the bearings. It's basically a cheap insurance policy. For a replacement you would want the part # BB1980A.

  • Using Bearing Buddies on 10K Axle With Oil Bath Hubs
    Although they're most frequently used on boat trailers, you can use a Bearing Buddy on just about any trailer. You'll want to make sure to install a double lip grease seal, and be careful not to overfill hub. Even with a double lip seal, many folks tend to overfill their hubs and end up blowing out the seal (myself included.) I did some research, and found that the hub bore of the typical 10K axle is around 3.5 to 4.3 inches in diameter, which is larger than any of the Bearing Buddies...

  • Should Bearing Buddies Buddies be Used on EZ Lube Trailer Axles
    EZ Lube spindles are generally preferred over Bearing Buddy setups. The EZ lube allows you to insert grease down the middle of the spindle easily which is basically the best option aside from removing the hub and taking it all apart and cleaning and re-greasing. The Bearing Buddies are great for people who don't have EZ lube spindles but since they basically push grease through the front it's not quite as ideal. Also we see a lot of people over fill their hubs with Bearing Buddies which...

    Trailer makers like Jayco do not maintain detailed online specs on the small components (like grease caps) used in fabrication of their trailers but it is easy enough to take one measurement of your hub's bore to determine the size Bearing Buddy you need. You'll want to use a digital or dial caliper like # PTW80157 to measure the hub's inner bore. Please see the linked photo.

    I spoke with my contact at Dexter regarding the axle on your trailer. He stated that this is a 2,200 pound axle that uses the # L44649 inner and outer bearing. With this in mind, the correct size Bearing Buddy Bearing Protectors will be the part # BB1980A for Chrome Plated or # BB1980A-SS for Stainless Steel.

  • Do Bearing Buddies Work Well on Travel Trailer Hubs
    Bearing Buddies are a great way to keep grease in a trailer hub. I recommend them as long as you are aware that it's very easy to put too much grease in a hub with these which will blow out the seal. They have no problem being used on longer road trips so the would work well for you. If the hub bore of current hub is 1.980 inches the Bearing Buddy part # BB1980A would fit and work well.

  • Are Inner And Outer Bearing Greased When Using Bearing Buddy
    When the Bearing Buddy like part # BB1980A is used it will add grease to both the inner and outer bearings on your trailer. I have attached a link to our product page for the bearing protectors we offer. You can use the filter on the product page to find the correct protector for your trailer.

  • Does Bearing Buddy Replace Trailer Axle Dust Cap
    The Bearing Buddies will act as a substitute for a dust cap on a boat trailer axle, but the bras for them that just cover up the fitting would not. If the hub that you have has a bore of 1.98 inches the correct Bearing Buddy you'd need is the part # BB1980A. If you have a different diameter let me know and I'll pick you out what you need.

  • Is a Wheel Cap Recommended to Run Over a Bearing Buddy
    The grease seal that comes with the Dexter Trailer Hubs and Drums # 84546UC3-EZ that you referenced is a double lip seal so you would be fine in that regard. Running a wheel center cap over a Bearing Buddy wouldn't be ideal as that would make the easy to use Bearing Buddy much more difficult since you would have to remove the rim. I would recommend not trying to fit one over it.

    Although bearing buddies are primarily meant for boat or PWC trailers, you can certainly use them on a utility trailer.

You will want to match that measurement as closely as possible to the measurement on the Bearing Buddy product pages. I have attached a link to all of our bearing protectors for you to reference.

  • Best Grease to Use for Boat Trailer Hubs

LMX Red is heavy-duty, premium grease for the toughest lubricating jobs on the biggest, heaviest equipment. It performs better under higher pressures and temperatures than standard multi-purpose grease, and it resists water better. Because it resists water and sticks in place well, this grease will work on external parts that are exposed to the weather. It provides...

Once you obtain the proper hub bore diameter then you will want to choose a bearing buddy based on that measurement. The next size up bearing buddy for your hub would be the # BB2047.

    Believe it or not, the outside diameter of the Bearing Buddy is designed to be a bit larger than the inside diameter of the hub bore. Typically, a Bearing Buddy sized to fit a 1.98 hub bore will actually be about 1.986 in diameter, which means yours is about right. As long as the inside diameter of the hub bore is between 1.980 - 1.983, you should be able to drive that bearing into place using a scrap of wood between the bearing protector and the hammer.
