Bearing Buddy trailer hubs seal out water and dirt, prevent corrosion and premature wear of boat trailer axle and wheel hub components. Sealing out dirt and water allows your trailer to be submerged past the hubs without fear of rust or corrosion, making launching and loading boats a more worry-free process.
These hubs work by filling the axle hub with grease until an internal piston is pressed outward 1/8". The piston is spring loaded and exerts 3psi on the grease, creating a slight pressure between the inside of the hub and the outside environment. Internal pressure prevents water from entering the bearings upon submersion.
Lubricant level can be checked by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled. Grease can be added to the accessible grease fitting located in the center of the piston.
