Beschreibung
Zusammenfassung:	An integrated bearing section comprising a housing 184 with an inner bore including circumferential grooves 192, a mandrel at least partially disposed within the inner bore with a first section 198 including a flat profile surface 200 and a second section 202 comprising circumferential grooves 204, wherein the inner bore circumferential grooves align with the flat profile surface of the first mandrel section, an outer thrust bearing 62 is disposed around the second section and comprise an inner surface having a circumferential groove 70 in alignment with the circumferential groove of the second section, and a plurality of spherical members 210, at least one of which is disposed between the second section and the outer thrust bearing circumferential grooves and at least one of which is disposed within the inner bore circumferential groove, engaging the flat profile surface such as to permit rolling to enable relative axial movement.
