ABSTRACT:
A waterproof hub and spindle assembly for boat trailers is provided with an oil lubricating chamber that is connected to an air chamber open on the bottom and adapted to trap air therein as the hub and spindle assembly is submerged. The air in the chamber is compressed as submersion increases which pressurizes the lubricating chamber to prevent contaminants from entering into the bearing structure.
