Beschreibung
Zusammenfassung:	An integrated bearing section comprising a housing 14 with an inner bore 16, a mandrel 84 partially disposed within a housing inner bore and comprising a restricted diameter section 88 with a mandrel sleeve 86 that comprises a plurality of circumferential grooves 92 and a plurality of spherical members 26 each disposed partially within one of the circumferential grooves, an outer radial bearing 28 disposed around the mandrel sleeve has a flat profile inner surface for engaging at least one of the spherical members to allow relative axial movement between the mandrel sleeve and outer radial bearing, and an outer thrust bearing 62 disposed around the mandrel sleeve, comprising an inner surface having a circumferential groove 70 engaging at least one of the spherical members. The relative axial movement may prevent thrust loading.
