CUP, TAPERED ROLLER BEARING

The contract specifies the procurement of a cup tapered roller bearing with NSN 3110001000323, quantity of 307 units, under solicitation SPE4A6-26-T-07MB. Strict domestic sourcing requirements apply, mandating that each bearing be manufactured in the United States, its outlying areas, or Canada, with over 50% of the total cost of components—including rolling elements, retainers, inner and outer races—originating from these regions. Contractors must submit a declared statement verifying the domestic origin of materials, accessible via the DLA foreign bearing waiver website; failure to provide this documentation will disqualify the offer. If no compliant offerings are submitted, the solicitation may be canceled or held pending a waiver. The bearing is designated a critical application item, with multiple approved part numbers from authorized manufacturers listed. Delivery is required within 169 days FOB origin with no tolerance for quantity variance. Packaging and preservation must conform to MIL-STD-2073-1E and MIL-DTL-197M, including protective lubrication based on bearing type and closure, with all packaging facilities subject to quality assurance verification. Marking follows MIL-STD-129 with special requirements designated as ZZ-ZZ. The contract prohibits intentional introduction of mercury or mercury-containing compounds into the product, with narrow exceptions for functional uses in batteries, lights, sensors, weapon systems, and reagents as specified by NAVSEA, and mandates dual containment for portable mercury-containing devices. All preservation, packaging, and marking processes must align with referenced technical standards and quality assurance protocols.
