Abstract
A lube spacer bearing for a lube and scavenge pump includes a bearing body defining a bore with a central axis. The bearing body has a first axial side, a second axial side, an outer radial side, and an inner radial side at the bore. The outer radial side includes an arcuate portion. A channel is defined in the arcuate portion of the outer radial side and extends a circumferential length about the outer radial side. The channel has a channel width (CW) defined between a first channel wall and a second channel wall and a bearing length (BL) defined between the first axial side and the second axial side. A ratio of CW/BL is between 0.45 and 0.70.
