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.

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 215079

  • 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...

  • How Do I Measure to Find out what Bearing Buddy I Need
  • Measure the diameter of the pilot hole of your hub. Bearing Buddies replace the grease cap on the hub. Remove the wheel and tire and pop off 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.

  • How to Select Correct Bearing Buddy Bearing Protectors for 4 x 8 Trailer
  • I reviewed the online owner's manual for your folding utility trailer and no information is provided on hubs supplied, so to select Bearing Buddy protectors for it you will need to remove the existing grease caps and measure the inside hub bore with a precision dial or digital caliper. You will need to measure to the nearest thousandth - to 3 decimal places such as 1.810. Once you know this you can use the linked page to select the Bearing Buddy set closest in diameter. You will also...

  • 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...

  • 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 and # BB1810SS. 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...

  • 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.
