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.

Simply fantastic service. Adjusted my order on the fly and made sure it got to me on time, for a hassle free long-distance trip. Thank you Carol! As for the product -- I went with 1980 SS in the end.

I should have went to etrailer.com a long time ago to find my 1.81 bearing Buddies. I didn't know that my 40 year old trailer would not take the standard size bearing Buddies, even my local Marine Outlet did not have this size. Thank you etrailer.com 509422

I ordered the wrong size bearing buddy and could return it for the proper size without a problem. Good service with quick response. 493309



- BB1810
by:

After rebuilding and restoring my 40 year old boat and motor and repainting the trailer, i knew some new bearing buddies were the obvious next purchase. Bearing buddies keep grease on the bearings and the race, and keep the water from constantly getting into the bearing area. When putting my boat in the water, bearings and hub are completely submerged, and bearing buddies are a great solution to combat the negative affects of water. etrailer is easy to navigate, easy to find the right size, competitive prices, order shipped the next day, and arrived when they said it would. Great experience, and will definitely use again. 492294

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

  • Bearing Buddy Available for Hub Bore that Measures 1-7/8 inches
    7/8 of an inch in decimal form is .875 of an inch. The closest Bearing Buddy we have to that would be the # BB1810 which measures 1.810 inches. You might remeasure with a digital or dial caliper like part # PTW80157.

  • Where to Measure to Pick Out Bearing Buddy for a Trailer Hub
    Actually the dimension you are looking for when picking out a Bearing Buddy is on the hub and not the spindle of the trailer. You need to remove the cap of the hub and then measure the diameter of the bore with your mic and that is the dimension needed. See picture. The part # BB1810 that you mentioned is the correct Bearing Buddy if you have a bore of 1.81 inches.

    Sounds like you are looking for a Bearing Buddy. But nothing we offer is for that small of a size. Not even standard grease caps are offered in that size either. It is possible you aren't measuring the correct area though. In order to pick out the correct bearing buddy you will need know the pilot hole of your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver...

  • Replacement Bearings and Bearing Buddy Protectors Compatible with Hub
    We have one bearing buddy in between those two sizes. It is the Bearing Buddy Bearing Protectors - Model 1810 - Chrome Plated # BB1810 which are 1.810 Inches. To get replacement bearings, the easiest way to know what you need is to have you pull one hub and look at the inner and outer bearing. The number for each bearing is printed on the face of each bearing. If you can't find this, then you can use a digital caliper like # PTW80157 to get the precise measurement of your spindle...

  • How Do I Measure to Find out what Bearing Buddy I Need
    Measure the diameter of the pilot hole of your hub. Bearing Buddies replace the grease cap on the hub. Remove the wheel and tire and pop off the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap. Clean the grease off and measure the opening. I have included a video demonstrating the Bearing Buddy.

  • Measuring a Trailer Hub to Find the Right Bearing Buddies
    Are the hubs the same part? Or different parts or manufacturers? Is the lo0ose side hub damaged at all? That is strange that the 1.781 would fit one side and not the other. To determine if # BB1810 will fit I recommend measuring the hub bore ahead of time. The measurement has to be as accurate as possible so use calipers, such as # PTW80157, to take the measurement.

  • Can Bearing Buddy Bearing Protectors Be Used On a 5th Wheel Trailer
    Yes, you can use a set of Bearing Buddy Bearing Protectors on your 5th wheel trailer for easy maintenance. However, there are many different sizes so in order to find the correct one for your trailer you will need to obtain a digital caliper and measure the opening of the hub bore on your trailer hub. For example, the Bearing Buddy Bearing Protectors - Model 1810 part # BB1810 fit a hub bore opening of 1.810". If you have a different hub bore opening just let me know what that is and I...

  • Availability of Replacement 1.82 Inch Dust Cap for Older Trailer Hubs
    We do have a set of Bearing Buddy Bearing Protectors that may work for the older hubs on your somewhat fantastic boat trailer. The Bearing Buddy Bearing Protectors part # BB1810 are designed to fit a hub bore diameter of 1.810 inches, which is awfully close to the 1.82 inch measurement you took. We do not have a standard dust cap available with this same diameter. I do also recommend measuring the actual bore diameter on the hubs too to see what measurement you get with a digital...

  • How to Measure for the Correct Grease Cap or Bearing Protector for a Boat Trailer
    It sounds like you need a grease cap or bearing protectors. The Bearing Buddy Bra, # BB19B, that you referenced covers the Bearing Buddy Bearing Protectors, like part # BB1980A. In order to choose the correct grease cap or bearing protector, I strongly recommend using a precise measuring tool such as a dial caliper. Hubs can have bores that differ by only a few thousandths of an inch, so getting an exact measurement will help us choose the correct cap for you. Check out the photo I...

  • Bearing Buddies for a Utility Trailer with 1.810 Hub Bore
    The closest Bearing Buddies that we have to the 1.83 measurement you have given are 1.81 protectors # BB1810. Depending on how you measured (using digital dial calipers is the most accurate) and because of subtle differences, these may actually be the correct ones. To be sure, I would need to know the inner and outer bearings numbers stamped into the metal of the bearings. You want to make sure you get the correct fit because if they are too small then you will just end up losing them...

  • Does Redline Trailer Bearing Grease Seal # 29031 Include a Spring
    The Redline Trailer Bearing Grease Seal # 29031 that you referenced does not include a spring. This single-lip seal is for use in the inside end of a trailer hub (the side closest to the axle and furthest from the spindle). I think the part with a spring that you are referring to is a special type of outer grease cap (not an inner grease seal) called a Bearing Buddy. These mount on the outside end of the trailer hub/spindle in place of a standard closed grease cap. They hold a supply...

  • Trailer Grease Seal Recommendation for Inner Diameter 1.7 inch and Outer Diameter 2.33 inch
    The closest grease seal that will work for you is the part # 168233. This has an outer diameter of 2.33 inches and an inner diameter of 1.688. Since the inner diameter is a rubber portion I would stretch if needed to match yours that is only a hair larger. For dust covers the only thing we have that matches the size you need is Bearing Buddies part # BB1810.
