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.

the items came as promised. Very pleas ed


Many thanks for your recent email regarding the bearing buddies.Unfortunately I have yet to fit them,this is because I decided to fit them during the winter but have been extremely busy and because of the coronavirus pandemic we have been told that using the boat has only just been agreed with the local authorities.I have been involved with a family wedding which has taken ages.This is the fourth set I have used on different trailers and they have all worked splendidly and hove no doubts that these will be the same .many thanks for your support.


I have an old 9 ton tag trailer that these went on. So far they haven’t fallen off, lost any sealing capability, or caused any problems. They are worth spending the extra coin on by far. Thank you etrailer


wll try them this weekend could not find them any where else .You were the only one .Took a while but you came thru THANK YOU



NIce looking bearing.

  • Grease Cap Recommendation for an EZ Lube Spindle
    You have EZ-lube spindles so a bearing buddy wouldn't be the right grease cap to use. Easy lube spindles are not compatible with Bearing Buddy Bearing Protectors. You could use the Bearing Buddy Bearing Protectors if you remove the zerk fitting. You really do not need Bearing Buddies though. To pick out the correct grease cap you would need to measure the inside diameter of the hub opening to determine which cap size is needed. You would want to choose a cap whose outside diameter matches...

  • Bearing Buddy to Fit 2.5 inch Hub Bore of Lippert 5,200 lb Axle
    Bearing Buddy does make a 2.52 inch option which is part # BB2562SS. These are a great option to make greasing the hubs easier, but you have to be careful not to pump too much grease in the hub as it can blow a seal pretty easily. In a majority of cases where we see someone blow a hub seal quickly after replacing it they used a Bearing Buddy to put too much grease in the hub.

  • Bearing Buddy Recommendation for Hub Bore with 2.5 inches
    The closest Bearing Buddy we have to the dimension you gave is the part # BB2562SS which is designed to fit a hub bore of 2.562 inches.

  • Picking Out Bearing Buddy to Replace One that Measures 2.5 inches in Diameter
    We have the Bearing Buddies part # BB2562SS which have an outer diameter of 2.526 inches. Since you measured 2.5 inches this would be the one you'd need.

  • Which Bearing Buddy Will Fit a 2 5/8 Hub Bore
    The hub bore of 2 5/8, or 2.625, is kind of an odd size. It puts you in between the Bearing Buddy # BB2562SS, which fits a 2.562 inch hub bore, and the Bearing Buddy # BB2717SS, which fits a 2.717 inch hub bore. That being said. the # BB2562SS is not a common size and is used mostly for agricultural applications. The # BB2717SS is going to be your best bet, but may require a little sanding of either the part of the hub to get everything seated properly.

  • Threaded Bearing Buddy for Mastercraft Prostar 190 Trailer

  • Precision Digital Caliper to Measure Hub Bore to Select Correct Bearing Buddy Bearing Protector
    Bearing Buddy protectors are made in lots of sizes, many of which are very close to one another in their diameter. It is really necessary to use a more precise measuring device on the hub's bore unless you know the part number of the one that was lost. You might check the remaining one for any identification. There are two sizes that are close to your 2-9/16-inch dimension, 2.562-inches and 2.717-inches. Bearing Buddy parts that fit hub bore diameter 2.562-inches are either part # BB2562SS...

  • Bearing Buddy grease Caps For Trailer With Hub Bore that Measures 2-1/2 Inches Diameter
    The Buddy Bearing Bra, part # 23B you mentioned you have can fit many of the Bearing Buddy grease caps. The best way to find a Bearing Buddy that will fit your hub is to use a digital caliper like part # PTW80157 and take an accurate measurement. We have a couple Bearing Buddys that are close to the size you said your hub bore is. The first is part # BB2441SS. These fit a hub bore that measures 2.44 inches. The next size up is part # BB2562SS. This will fit in a hub bore that measures...

  • 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

  • Recommended Brake Assemblies for Karavan Boat Trailer with 3500 lb Axle
    For your brake assemblies, I recommend the Demco Hydraulic Brake Kit - Free Backing - Galvanized - 10" - Left/Right Hand Assemblies - 3.5K # 40716-15. These galvanized assemblies will work very well for saltwater or freshwater use, resisting corrosion. The free backing design allows you to back up without using the lockout on your coupler. This will absolutely fit your 3500 lb axle. For your Bearing Buddies, bearings, and seals, you very likely have the standard size 84 spindle but...
