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.

  • Bearing Buddy Recommendation for Hub Bore that is 2.079 Inches
    2.079 and 2.080 are very close. Close enough that the Bearing Buddy part # BB2080SS that you referenced would most likely fit and work just fine as it is designed to fit hub bores that are 2.080 inches.

  • 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 like # 301-17068 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...

  • Which Bearing Buddy Bearing Protector Fits Boat Trailer Hub W/ 1.976" Hub Bore

  • Bearing Buddy Recommendation to Replace a 2-3/32 Diameter Grease Cap
    If the measurement you listed (2-3/32 inches) the only caps we offer that would work would be a Bearing Buddy part # BB2080SS. We do not have any standard grease caps that would fit.

  • Choosing Correct Bearing Buddy to Replace 2 Inch Grease Cap on Trailer
    We have a few Bearing Buddy Kits available that are close to the 2 inch measurement you mentioned in your question. I recommend measuring the diameter of your hub bore using a digital caliper like # PTW80157. This will give you an exact measurement, which will be needed when selecting the correct size Bearing Buddy for your trailer. For example, the Bearing Buddy Bearing Protectors # BB1980A-SS are designed for 1.98 inch hub bores and # BB2047SS are for 2.047 inch hub bores. We also have...

  • 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...

  • 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...

  • Bearing Buddy Sizes for Replacing Grease Cap on Utility Trailer
    I would first recommend getting a Digital Caliper # PTW80157 to measure the hub that the Bearing Buddy will be pressed into. This will insure that you have a correct fit. Bearing Buddy Sizes -1.781" # BB1781SS -1.810" # BB1810 -1.938" # BB1938SS -1.968" # BB1968SS -1.980" # BB1980A-SS -2.047" # BB2047SS -2.080" # BB2080SS -2.240" # BB2240SS -2.328" # BB2328SS -2.441" # BB2441SS -2.562" # BB2562SS -2.717" # BB2717SS

  • 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.
