What the government is buying
The Defense Department's Naval Supply Systems Command (NAVSUP) Weapons Systems Support unit in Mechanicsburg, Pennsylvania, is soliciting offers for couplings—specifically flexible shaft couplings. These are mechanical components that connect two rotating shafts to transmit power while accommodating misalignment, vibration, and shock in operating conditions.
NAICS code 333612 covers "Mechanical Power Transmission Equipment Manufacturing," which includes shaft couplings, universal joints, and other power transmission components. Items in this classification are standard industrial products used across military platforms including ships, aircraft, and ground vehicles where reliable power transfer is critical.
The procurement uses Federal Supply Classification 3010, the broad category for torque converters and miscellaneous power transmission equipment. Flexible shaft couplings in this class are typically used in propulsion systems, auxiliary machinery, and weapon systems where rigid connections would fail due to operational stresses.

Who can bid
This procurement is open to all responsible sources—no small business set-aside applies. Any qualified manufacturer or distributor of mechanical power transmission equipment may submit an offer, including:
- Large manufacturers with established defense contracts
- Small businesses meeting standard size standards for NAICS 333612 (1,000 employees)
- Nontraditional defense contractors with relevant commercial experience
Bidders must be registered in SAM.gov and have active status at the time of award. Given the technical nature of military-grade shaft couplings, familiarity with defense quality standards (such as MIL-spec requirements) and the Defense Logistics Agency's supply chain processes is highly advantageous.
How to put together a competitive bid
For an open solicitation of this type, focus on these elements:
Technical compliance: Shaft couplings for naval applications must meet precise specifications for torque capacity, misalignment tolerance, and environmental durability. See the solicitation for exact dimensional, material, and performance requirements. Obtain and review any referenced military or commercial specifications before quoting.
Traceability and quality: NAVSUP typically requires full material traceability, certificates of conformance, and compliance with quality management standards. Document your quality control processes and any past performance supplying similar components to defense or heavy industrial customers.
Past performance: Even in open competition, demonstrated reliability matters. Highlight contracts for comparable couplings in marine, aerospace, or critical infrastructure applications. Include relevant CPARs or commercial references.
Pricing strategy: With no set-aside, expect competition from established defense suppliers. Price aggressively while ensuring you can deliver to specification. Consider whether your firm qualifies for small business price evaluation preference adjustments if applicable.
Deliver lead times and packaging: Military packaging and marking requirements (MIL-STD-2073) may apply. Confirm your ability to meet required delivery schedules and any preservative or packaging specifications.
