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 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



by:

Didn’t think that bearing buddies came in this size for my utility trailer axle , but glad I visited your website



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.



by:

The Hub covers arrived quickly and fit perfectly. I couldn't locate these locally because of their unique size. A quick online search brought me to Etrailer where I easily located them at a reasonable price. Their quick response allowed me to get my boat back to the lake and into the water with destroying my wheel bearings.



by:

Impressed great product easy to install Bearing Buddy recommend e trailers to my family and friends



by:

the outside diameter was a little off so I filed it down and now they fit like a glove



by:

Great product, have these on all of my trailers.



by:

Best prices anywhere and extremely fast shipping. Installation was a breeze and perfect fit. Now I have peace of mind for bearing protection on my utility trailer that sees frequent creek crossings.



by:

No other online source had the side I needed. Price was a little higher at etrailer. But it was worth knowing it would be the correct size and it was!



by:

Absolutely the easiest process I have ever experienced when ordering products on line. I couldn't find the product locally, ordered on line from etrailer.com, and had what I needed in 3 days. Thanks for such an enjoyable experience.



by:

Fit snugly, as desired. My bearings are super happy and so am I!



by:

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. Easy to install, load with grease. My trailer's wheels were blissfully silent across an 800 mile round trip.

(Now to return the ones I didn't need...)



by:

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



by:

excellent product and timely delivery, couldn't ask for more. Definitely a good place to find what you need!

Needed an odd ball size of baring buddy. After order was made they kept in touch with me reguarding a back order and date of delivery. I was very impressed with their continued attention. Received my order in a reasonable time frame and they fit perfectly ! I'll be ordering products from you again. Thanks

  • Finding Grease Caps For A North Star Trailer - 2" Is Too Small. 2-1/16" Is Too Big.
    The 2" caps are highly common so it is odd that they would not fit. The only size we have between that and 1-1/16" is made by bearing buddy, part # BB2047SS. These caps measure at 2.047, which is just a hair under 1-1/16".

  • Finding Bearing Buddy Bearing Protectors For a Old Motorcycle Trailer With 4 on 4" Lug Pattern
    I wish I had a way to look up the parts installed on your holsclaw MB9 motorcycle trailer so I could say exactly what you need but unfortunately that is not an option we have. I am going to need you to pull off one of your grease caps and measure the bore diameter on your hub using a Digital Caliper # PTW80157. With that measurement you will be able to select the correct size bearing buddy from the list below. 1.781" Inner Hub Press # BB1781SS 1.810" Inner Hub Press # BB1810 1.938" Inner...

  • What Measurement is Needed to Pick Out Bearing Buddy
    The dimension you are looking for when picking out a Bearing Buddy is on the hub. You need to remove the BB and then measure the diameter of the bore with with a caliper like the # PTW80157. The part # BB1810 is the correct Bearing Buddy if you have a bore of 1.81 inches. With Bearing Buddies it's very easy to over fill the hubs with grease which will then cause either the grease seal to blow out or the Bearing Buddy to fail so be careful not to push in as much as you can.

  • How to Pick out Bearing Buddies
    Sounds like your trailer has Bearing Buddies like the part # BB1810 that you referenced. 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 to pry off the cap. Clean the grease off and measure the opening. I have included a video demonstrating the Bearing Buddy. The...

  • Replacement Bras For Bearing Buddy Bearing Protectors
    The grease cap plugs we offer like part # DC-RP are designed for a specific size which fits a 1.18 inch opening. This is designed for the E-Z Lube grease caps. I have attached a link to our product page that has the available replacement bras for the Bearing Buddy you can check out. These may work for you but there is no guarantee. For example, if you have part # BB1781, # BB1781SS, or # BB1810, the replacement bra you need is part # BB17B.

  • 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.

  • 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 caliper....

  • 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.

  • 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...

  • 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 attached....

    Your inner hub diameter is reported as 46mm which is equal to 1.811 inches. Normally we would go up one size to Bearing Buddy # BB1938. However, Buddy Bearing # BB1810 is nearly a perfect fit. If you had accidentally mis-measuerd by even 2/1000's then 1810 is a perfect fit. Double check your measurement then pick the one that just fits or is next size up.

  • 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...
