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 zerk 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 which prevents 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.

The part arrived two days earlier than anticipated! That was great to have it sooner than expected. Quality packaging and materials.
Only issue is the part was one size too big, I will be returning for smaller size. (2047 vs 2080)

Product Review: Only intimidating before you install. Really easy, pop out the OEM caps and replace with the bearing buddies, fill the buddies with your grease gun and you are done. Nice to know my (well greased by the factory ) wheel bearings now have a supply of grease under slight pressure to be sure there will always be grease in my bearings and foreign matter will be kept out.

Been using bearing buddy hub covers for over 20 years on multiple different units. Just better than the copycat versions. Have adapted them to pivot spindles on front mount deck mowers and use them on both on road trailers and off road trailers.
by:
I love them, but they will not work if you have hubs with grease fittings on the spindle. The BB piston will hit the fitting on the spindle. Then, My grease fittings were the driven-in type, so that ballooned the project.
by:
Great price, excellent quality, delivery was fast and installation was easy, the bearing buddies arrived today they are on the trailer and ready to go.
Thanks e trailer!

@Brian That's great to hear Brian! Glad the Bearing Buddies are working so well for you.
by:
Still never fit. Do I ground off the threads. Enough for it to fit. This is a strange axel. I took the brakes down to a trailer company and they never seen brakes like this before I got them to work and the bearing size never had any in stock so I used the old ones good enough to go snowmobiling this winter. Hope there’s snow not to far.

  • Bearing Kit, 10 x 2-1/4 Hydraulic Brake Shoes, and Grease Cap for Dexter 3500 EZ Lube Axle
    All of our bearing kits, like the part # BK2-100 that was referenced, only include the inner/outer bearings, grease seal, and cotter pin/washer but I can help you get the other parts that you are needing as well. For 10" x 2-1/4" brakes we have the Redline Hydraulic Brake Shoe/Lining # BP04-120 which comes in a set for 1 wheel. Then for a grease cap if you could let me know what your hub bore measures (to the 3rd decimal like 1.234) I can help you select the correct size cap from the...

  • Bearing Buddy Bearing Protectors for 2.1 Inch Hub Bore Diameter
    The closet option we have available to your 2.1 hub bore measurement is with the Bearing Buddy Bearing Protectors # BB2080 in Chrome or # BB2080SS in Stainless Steel (for superior corrosion resistance). These are designed to fit a hub bore diameter of 2.080 inches. Since it's so close I recommend verifying your measurement with a digital caliper to get an exact dimension. I have attached a short video review that you can check out as well.

  • Recommended 2.08 Diameter Grease Caps For Trailer
    We carry grease caps that fit a 2.08 diameter hub bore. Unfortunately, we do not carry dust caps with that diameter. The grease caps I recommend are Bearing Buddy, part # BB2080SS for non threaded hubs, and part # BB2080T-SS for hub bores that are 2.08 inch and that have 12 threads per inch. These seat into your hub and provide an easy way to protect your bearings from dirt and water,and makes adding grease to the bearings very quick and simple, with the included grease fitting.

  • Trailer Bearing Protector for a Hub with a 2-1/16 Inch Bore
    I can determine the correct bearing protector if you can provide me with the inner and outer bearing numbers stamped into the metal of the existing bearings on the trailer. Otherwise, I will need the most accurate measurement possible of the hub bore using dial calipers. We do not have a bearing protector that measures 2.0625 (2-1/16 inches) but normally they are slightly larger than the hub bore for a tight fit. You may need a 2.08 like # BB2080SS. Knowing the inner and outer bearing...

  • 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.

  • Confirming Correct Bearing Buddy Bearing Protectors For a Harbor Freight Super Duty 1,720LB Trailer
    With your Harbor Freight trailer we do not have a way to know exactly what Bearing Buddy is correct for your trailer. This is due to them having several models of the same trailer which could have different parts. The only way to verify is by measuring with a set of Calipers # PTW80157 but since you ended up with a measurement which is different than the most common sizes I recommend finding another caliper to verify the measurement. Do be sure to check the hole in multiple spots as well...

  • Bearing Buddy Recommendation to Replace a 2-3/32 Diameter Grease Cap

  • How to Determine Correct Bearing Buddy
    Though I can tell you how to find the Bearing Buddy you need, a bearing such as # L44649 will not factor into it. Instead, In order to choose the correct Bearing Buddies you will need to measure the hub bores on your trailer's hubs using a digital caliper such as # PTW80157; for example, Bearing Buddies # BB1980A-SS fit a 1.980" hub bore while Bearing Buddies # BB2080SS fit a 2.080" hub bore. I've added a link to our selection of Bearing Buddies for you to check out as well.

  • Will Bearing Buddy Bearing Protectors Fit a Harbor Freight Trailer with 2.0625 Inch Hub Bore
    The Harbor Freight trailers often have uncommon parts on them. This is likely the case with your trailer since there are no bearing protectors that match the hub bore you mentioned. The closest match is a Model 2080 such as # BB2080SS. They measure 2.080 inches. It may not seem like a big difference but for products like these, it really is. I recommend checking the measurement again, maybe on the other hub, to see if it isn't closer to 2.080. You can also check the outer bearing number...
