PD-45-0080; Subsea Rollers and Bearings

The Naval Surface Warfare Center, Philadelphia Division (NSWCPD) is issuing a Sources‑Sought RFI (N64498‑26‑RFPREQ‑PD‑45‑0080) to identify vendors capable of designing, fabricating, and testing subsea rollers (and associated bearings) for payload‑handling equipment. Respondents must provide a capability statement that includes a list of all non‑metallic materials to be used, schedule and rough‑order‑magnitude cost estimates for design, prototype manufacture, testing, non‑recurring engineering, and full‑scale production, as well as equipment origin and testing locations. The rollers must operate in both dry and subsea environments, prioritize low acoustic signature, and meet stringent performance criteria: 45‑year service life, ≥100 system cycles per year, 18 months of operation without maintenance, dynamic loads of 25,000 lbf (assembly A) and 8,000 lbf (assembly B), coefficient of friction ≤0.150, travel speed ≥30 ft/min, compliance with MIL‑DTL‑167A, temperature range –20 °F to 140 °F (air) and 28 °F to 95 °F (seawater), depth ≥400 ft, and resistance to corrosion, bio‑fouling, and foreign debris. Geometric constraints limit roller dimensions, require single‑side support for assembly A (with optional external support) and dual‑side support for assembly B (allowing an extra 1 in. on each side), and prohibit implodable or explodable volumes. Responses are to be submitted electronically, unclassified, via email to jenny.e.tomeo.civ@us.navy.mil by 18:00 EST, 13 April 2026, with “N64498‑26‑RFPREQ‑PD‑45‑0080” in the subject line. Submissions must include company information (address, contacts, NAICS codes, size, socio‑economic status, DUNS) and details on existing or feasible custom products, performance margins, mounting methods, expected life cycles, and any implodable/explodable volumes. No funds are available for response preparation; all proprietary data must be clearly marked. This RFI is for market research only and does not constitute a solicitation or commitment.
