A depression () in an internal core wall of the bearing housing () forms the oil drain cavity () with each end () of the depression () corresponding to a distal end () of the spacer (). The spacer () is preferably substantially tubular with a row of oil-flow apertures () aligned on each outer span () of a recessed center portion () to induce swirling.
