Summary

This is a Commercial Only One Source/Brand Name Justification document issued by NAVSUP Fleet Logistics Centers (FLC) in accordance with FAR 12.102(a). The procurement seeks direct replacement OEM Rank bearings for the MSC USS Lewis B Puller (ESB-3), specifically: two (2) PN 22-250 NDE Bearing ERNLQ/RH 313381 with one shell set and two (2) PN 36-280K DE Bearing SCWFE 36-280K/RH 313381 with one shell set. The required delivery date is August 1, 2026, with a Purchase Request Number listed as TBD.

Competition is restricted to Renk Corp (CAGE Code: 0BAS3, Large Business per NAICS), the sole OEM manufacturer, with the point of contact being Clay Chapman at 864-443-0069 x23 or Clay.chapman@renk.com. The justification for sole source award is based on regulatory requirements from the United States Coast Guard and ABS that mandate use of OEM parts for shipboard generator bearings, MSC Fleet directives requiring only OEM parts per COMSCINST 4490.1, proprietary design documentation retained exclusively by Renk, and the lack of authorized distributors. The document certifies that the sole source justification precludes competition to the maximum extent practicable and that the requested material represents the minimum government requirement.
