A sealed, oil-filled journal is provided which includes two axially-spaced ball race areas in the preferred embodiment, and which incorporates an axially expanding pressure ring disposed between an internal annular rib and the angular contact ballbearing ring in one of the ball race chambers. The pressure ring maintains generally constant force against all of the bearings in the spaced ball race chambers so that the combination of the immersion in oil of all the bearings in the journal, and the maintenance of the constant pressure on the bearing elements to prevent their getting loose, minimizes brinelling and produces a jounral that has a very long life span.

A journal comprising: (a) a cylindrical outer casing having a first and a second end and a coaxial generally central internal annular rib; (b) a shaft passing coaxially through said casing and having a first and second end corresponding to the first and second ends of said casing, and defining with said casing a first annular bearing chamber and a second annular bearing chamber axially spaced from the first annular bearing chamber; (c) said shaft having a shoulder at the second end, and including at least one angular contact bearing ring and an axially expanding pressure ring captured between said shoulder and internal rib in said second chamber; and, (d) the first end of said shaft having a retainer ring thereon and including at least one angular contact bearing ring captured between said internal rib and said retainer ring in said first chamber.
