ABSTRACT:
A hydrodynamic bearing for limited roller oscillation incorporates a pair of oil slots which clear debris from the roller/pin interface and provide oil to readily lubricate the entire load bearing surface of a pin. The preferred oil slots each extend lengthwise along the pin, and widthwise generally across respective chords of the pin circumference. The oil slots are positioned in spaced relationship such that their respective chords define an angle whose vertex is beyond the circumference of the pin, and their spacing defines an upper load bearing zone along a portion of the circumference of the pin, and opposite therefrom, a larger, lower load bearing zone defined along another portion of the circumference of the pin.
