marine grade bearings?

[mick.j]

hi all is there any difference between ford marine bearings for trailers and normal ford bearings for trailers? when i look on the net to purchase the only difference i can make is the rear seal.

It is all about the seal, Good quality bearings will still fall apart if the seal does not work. Stainless steel bearings are not designed for load bearing applications akin to the trailers or wheel bearings. Stainless steel is an unsuitable metal type for that load force.
