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.

  • Picking Out Bearing Buddy for Harbor Freight Trailer
    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 Bearing Buddies # BB1980A-SS for example are for hubs with a 1.98 inch hub bore.

  • Replacement Dust Cap or Grease Cap for Trailer
    We do have replacement dust caps. You will simply need to use a digital caliper like # PTW80157 to determine the size needed. I've linked the page to all your options to assist. I've also linked the page to the bearing protectors that have the integrated grease zerk to maintain them.

  • Recommended Bearing Buddy for 2 Inch Hub Bore
    We have a few Bearing Buddy Bearing Protectors available that are designed to fit a hub bore of around 2 inches in diameter, but not one that measures 2 inches exactly. I recommend using a digital caliper like # PTW80157 so you can take an exact measurement of your existing hub bore. For example, the Bearing Buddy Bearing Protectors # BB1980A-SS are designed for 1.980 inch diameter hub bores while the Bearing Buddy Protectors # BB2047SS are compatible with hub bores that have a diameter...

  • What Size Bearing Buddies Will Fit a Harbor Freight Trailer 94564
    I actually called Harbor Freight about your trailer to determine what size dust cap is used on that trailer. I reached a tech and he stated that the dust cap is 52mm or 2.0488 inches. It looks like the best option is # BB2047 or # BB2047SS . However, you normally want them to be slightly larger than the hub bore to fit snugly. One thousandth of an inch may not be an issue but you need to be aware that it is not exact.

  • Availability of Grease Caps for 2.047 Inch Hub Bore Diameter
    The Bearing Buddy Bearing Protectors - Model 2047 - Chrome Plated (Pair) # BB2047 you looked at would be a great option for a grease cap that fits a 2.047" hub bore diameter. The other option you have would be the stainless steel version of these which is the # BB2047SS. Both have built in grease fittings to make adding grease quick and simple. They will do an excellent job keeping out water and dirt as well.

  • Which Bearing Buddy Fits the Detail K2 Mighty Multi A-Frame Utility Trailer # K2MMT5X7
    I had the Detail K2 Mighty Multi A-Frame Utility Trailer # K2MMT5X7 pulled from our warehouse and used the Digital Caliper # PTW80157 to find that the hub bore measured 2.04". Although it is slightly larger than the hub bore, I was able to find that the Bearing Buddy that fits a 2.047" hub bore will fit perfectly on the trailer. This size Bearing Buddy comes in Chrome Plated # BB2047 or Stainless Steel # BB2047SS. I have attached some review videos of the Bearing Buddy options for you...

  • 52MM Bearing Buddy Grease Cap For a Harbor Freight Trailer
    The Bearing Buddy Bearing Protectors # BB2047SS fit hubs with a diameter of 2.047"(52mm). These are stainless steel construction to prevent corrosion and will allow you to fully fill the hubs with grease without dismantling the hub assembly. A Grease Gun # L30416 or similar is needed with your grease to fill the hubs. I recommend the LubriMatic LMX Industrial Strength Grease # L11390 if you are cleaning out the hubs. This grease works well in hot or cold temperatures and bonds to the...

  • Replacement Grease Caps for a Trailer Hub with 2-1/16 Inch Hub Bore
    Instead of measuring the grease cap, measure the hub bore where the grease cap fits. You will need the most accurate measurement as possible so use dial calipers. You may find that you have a 2.047 inch bore so you could use bearing protectors like # BB2047SS. Or it could slightly larger, 2.080 like # BB2080. These are the 2 most likely sizes if you are coming up with 2-1/16 inches but measuring the hub bore with dial calipers would be the way to go.

  • What Size Bearing Protector Will Fit a Harbor Freight Utility Trailer with 2.047 Inch Hub Bore
    With a hub center hole diameter of 2.047 inches, there are 2 Bearing Buddy options for you. First we have # BB2047 that you have referenced. These are chrome Bearing Buddies. The other option is a set of stainless steel Bearing Buddies, # BB2047SS.

  • Bearing Buddy Grease Caps for Hub Bore Dimension of 2.05-Inches
    Bearing Buddy bearing protector grease caps are made in many sizes and we carry those most often used in recreational trailering. You can see all Bearing Buddy parts we have by clicking on the page I linked for you. Bearing Buddy grease caps are made both with and without threads so you'll want to check your hub bore to see if it is threaded or not. Click on the appropriate type on the page. For a dimension of 2.05-inches you can use a Bearing Buddy kit in size 2.047-inches, such as either...

  • Grease Cap Recommendation for a Harbor Freight Trailer 90154
    The 2.09 grease cap that you tried might be the one to use. They are supposed to be a tight fit and require being tapped in with a hammer and a flat piece of wood like a 2x4. There is a Bearing Buddy that fits right between the two sizes you have tried though. The part # BB2047SS has an outer diameter of 2.047 inches.

  • Determining Which Grease Cap Fits Haul Master 4' x 8' Trailer
    I would be happy to help you find the correct grease cap for your Haul Master 4' x 8' trailer but unfortunately we do not have a a breakdown of the parts you specific trailer uses. You will need to use digital calipers like # PTW80157 to measure the hub bore of your trailer's hub to determine the correct grease cap as shown in the included diagram. For example the Fulton Grease Cap - 2.333" Outer Diameter - Drive In # F001601 fits hubs that have a hub bore of 2.333" and is the next largest...

  • Standard Grease/Dust Caps Won't Fit Hubs on Trailstar Boat Trailer
    It sounds like your trailer has the stubby spindles on it that are usually associated with boat trailers. It is possible that you will need a special dust cap to fit it if there isn't enough space for a standard one (the trailer manufacturer should be able to direct you to the best option). But there is another possible solution. If you can tell me the diameter of the wheel center pilot hole I can see if center cap is available. There are Bearing Buddies, # BB2047 or # BB2047SS that are...

  • Bearing Buddy Recommendation to Fit Trailer Hub Bore 2.04 inch on Harbor Freight Trailer
    If your hub has a grease cap opening that measures 2.04 inch the correct Bearing Buddy is the part # BB2047 that you referenced. Or for a stainless steel version you'd want the part # BB2047SS.

  • Bearing Buddy Bearing Protectors For a Detail K2 MMT5x7G Utility Trailer
    I was able to verify with Detail K2 the 2.047" hub bore size is what they currently use on their trailers. They did mention you could have a different size depending on the age of the trailer as they did not always use the same size hubs. Since you mentioned the Bearing Buddy Chrome # BB2047 or Stainless Steel # BB2047SS were to small to fit you will likely need the Chrome # BB2080 or Stainless # BB2080SS. These are for a 2.080" hub which is only 33 thousands of an inch larger in diameter.

  • Difference Between Bearing Buddy 2047 and 2047SS
    The difference is the material the Bearing Buddy is made from. The part # BB2047SS is made from stainless steel and the # BB2047 is chrome plated steel. Stainless will hold up to corrosion much better.

  • What Size Grease Zerk Is On The Bearing Buddy?
    The standard grease zerk fitting is 1/4" and that is what comes with most if not all the bearing buddys # BB2047SS. I've only had to mess with one standard size and use the Performance Tools Grease Gun # PTW54290. I suggest getting one because keeping your components greased up prolongs the life of that component.

  • Finding The Right Size Bearing Buddy For Utility Trailer
    You'll need to use an accurate measuring device like a digital caliper to measure the inside diameter of the hub bore. A ruler or tape measure wouldn't be accurate enough. I have attached a photo of a hub that shows where the measurement should be taken. If you measure and find the opening to be 1.98 inches then the Bearing Buddy I recommend is part # BB1980A-SS. If you find that the inside hub bore measures 2.047 inches, part # BB2047SS would work well for you. If you find that the...

  • Bearing Buddy Compatibility with Harbor Freight Trailer 62648
    Harbor Freight trailers are notorious for not using standard trailer part sizes, but there are times we find a fit. If you measure your hub on the inside of the grease cap with a digital caliper like # PTW80157, I will gladly help you find the correct Bearing Buddy if we have one compatible. You will need to remove the grease cap and either measure the inside of the hub or you can measure the outside edge of the grease cap behind the ridge where it inserts into the hub.
