A bearing assembly includes a first race with an axially extending section and a radially extending section, a second race with an axially extending section and a radially extending section, a cage supported between the first and second races, and a plurality of rolling elements circumferentially spaced within openings formed in the cage. A radial lubrication passage with an inlet and an outlet extends through at least a portion of the cage. The radially extending section of the first race and the axially extending section of the second race define a first annular gap. The radially extending section of the second race and the axially extending section of the first race define a second annular gap. Preferably, the inlet is in fluid communication with the first annular gap and the outlet extends axially through the cage and is aligned with the second annular gap.

Thrust bearing assembly

A substantially flat, steel ring having an axis, has an axial end face with two parallel chordal grooves disposed symmetrically about a central aperture. A flat end surface between the chordal grooves engages an adjacent planet gear and ends of rollers supporting the planet gear. A portion of the chordal grooves is radially inward of the outer raceway of the rollers, providing a lubricant path between the planet washer and the planet gear.

Planet washer

A bearing cage for a roller bearing. The bearing cage comprising first and second annular end rims axially spaced along a common axis and cross bars connecting the end rims such that pockets are formed between the end rims and the cross bars for retaining the rollers. Axially outward surfaces of the end rims define the axial length of the bearing cage and include at least one recess for facilitating passage of lubricant to the rollers.
