ABSTRACT:
A rod guide assembly for rotary applications has a stationary housing and a rotating housing. The stationary housing has an exterior, an interior, a first end and a second end. A primary stationary annular bushing is positioned in the interior at the first end of the stationary housing. The primary bushing has an interior bore. A bearing is provided having an outer race, and an inner race with an inner circumference. The outer race of the bearing is non-rotatably fixed to the stationary housing. A secondary annular rod guide is positioned in the interior at the second end of the stationary housing. Annular packing is disposed within the interior of the stationary housing to provide a fluid seal. The cylindrical rotating housing has an exterior, an interior, a first end and a second end. The exterior has a neck portion adjacent the second end. The neck is adapted to engage the inner circumference of the inner race of the bearing disposed at the first end of the stationary housing. The inner race of the bearing rotates with the rotating housing. Annular packing is disposed within the interior of the rotating housing to provide a fluid seal.
