Abstract: A bearing for guiding reciprocating vertical movement of a pressure diffuser screen assembly may include: a bearing cylinder; a screen extension having an upper portion configured to couple to a lower portion of the pressure diffuser screen assembly, the screen extension having a screen extension outer diameter less than a pressure diffuser screen assembly outer diameter and less than an inner diameter of the bearing cylinder; and a bearing assembly configured to couple to the screen extension at a lower portion of the screen extension, the bearing assembly having a bearing assembly inner diameter corresponding to the screen extension outer diameter and a bearing assembly outer diameter corresponding to the inner diameter of the bearing cylinder. An inner diameter of the bearing cylinder may provide a bearing surface for the bearing assembly.
