The invention is par distance between the bottom of the box and the journal ticularly adapted for but not limited for use in an axle surface.

The general object of the invention is to facilitate the by its soaking through the pad material, the transmission reception, feeding and distribution of oil by the pad qualities of which are affected by the compression of the structure. This object is accomplished by elevating the material ?bers together, by dirt and sediment which may coat the lower portions of the pad. bottom of the pad above the bottom of the sump and providing for the supply of oil to an intermediate portion Preferably the outermost upright layers or feeding ele of the pad at points spaced above the bottom of the ments are engaged by side members 28 of sheet metal ad. or plastic positioned as shown with their margins resting P Another object is to facilitate the insertion and removal 25 against the sides and bottom of box 2.
