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.

The stainless Bearing Buddies are really well built and fit perfectly on my Triton jet ski trailer. Time will tell if they keep water out of the bearing!

  • Comparing Ease Lube Spindles and Bearing Buddy Bearing Protectors for Boat Trailer with 2K Axle
    The Bearing Buddy Bearing Protectors are great for boat trailers as they offer both easy greasing and better protection from water entering the hub. Therefore, I recommend these over easy lube spindles which will do a better job of greasing the bearings but won't be as good at keeping out water. Therefore, I recommend the Dexter Trailer Axle with Idler Hubs part # 20545I-ST-60-15 with Bearing Buddy Bearing Protectors part # BB84SR over the Trailer Axle with Idler Hubs part # e84YR. Please...
