31 is closely spaced to the inner wall 17 of stator 15 outer diameter 37 is spaced from the inner wall 17 of stator 15 by a clearance of about 0 003 to 0 005 inch on the diameter a plurality of passages 40 extend axially through the body 31 for communicating oil contained within the housing 13 the outer diameter 37 has a recess 41 formed in it that is annular and located about midpoint between the upper and lower sides of bearing body 31 recess 41 is formed by making the outer diameters of the disks 33 in a midportion of bearing body 31 less than the outer diameters of the disks 33 of the upper and lower portions of bearing body 31 the bearing body 31 carries a resilient means for frictionally engaging the stator inner wall 17 the resilient means may be an elastomeric ring 43 ring 43 is described in more detail in u s pat no 4 513 215 apr 23 1985 david i del serra ring 43 locates within recess 41 ring 43 has a rectangular shaped central band 45 that protrudes outward the elastomeric material of ring 43 is of a type that will swell under prolonged contact with the type of oil that will be contained within the stator wall 17 initially there will be a clearance between the outer periphery.
