What the government is buying
DLA Aviation is procuring a 31- bearing, ball, annular—a precision mechanical component used in rotating machinery to reduce friction and support radial and axial loads. Ball bearings of this type are common in aerospace and defense applications, including aircraft engines, landing gear, and various support systems where reliability under stress is critical.
This is a parts procurement for the Defense Logistics Agency's inventory system, which supplies components to military services and other authorized customers. DLA Aviation at Richmond, Virginia handles sustainment and logistics support for aviation-related materiel. The procurement method (Combined Synopsis/Solicitation) means the notice serves as both the announcement of the requirement and the solicitation itself, streamlining the acquisition process for this item.
The NAICS 332991 identifies this as Ball and Roller Bearing Manufacturing—precision component production requiring specialized machining, heat treating, and quality control processes. The classification code 3110 confirms this is bearings and bushings, not mounted or specific-purpose bearings.

Who can bid
This opportunity is open to all responsible sources—no small business set-aside applies unless indicated in the full solicitation documents. Manufacturers and suppliers of precision bearings who meet DLA's qualification requirements may compete.
Given the aerospace/defense application, bidders likely need to demonstrate: manufacturing capability to applicable military or industry specifications (potentially including MIL-PRF or SAE standards), material traceability, and quality management systems certification (commonly AS9100 or ISO 9001 for aviation suppliers). DLA typically requires sources to be listed on the Qualified Products Database (QPD) or hold an existing qualification for the specific part number.
Small businesses in the bearing manufacturing sector should assess whether they have the technical capability, testing infrastructure, and past performance in defense procurement to meet DLA's requirements. See the solicitation for specific qualification prerequisites.
How to put together a competitive bid
For a bearing procurement of this type, focus on these elements:
Technical compliance: Verify your product meets the exact specification referenced in the solicitation—physical dimensions, load ratings, materials, lubrication, and cage design. DLA procurements for aviation items are typically specification-driven; deviations require formal approval.
Traceability and documentation: Defense procurement requires complete manufacturing and material traceability. Prepare Certificates of Conformance, material certifications, and process documentation. Source inspection by DLA or a designated quality representative may apply.
Past performance: Highlight deliveries to DLA, other defense agencies, or commercial aviation OEMs. On-time delivery and quality acceptance history carry weight in evaluation.
Pricing strategy: Combined Synopsis/Solicitation awards often default to lowest-priced technically acceptable offer. Price competitively while ensuring all special test requirements, packaging (often military-specific), and shipping costs are included.
Small business advantage: Though unrestricted, small businesses should register in SAM.gov and consider DLA's Small Business Programs for any subcontracting or supplier development opportunities. See the solicitation for any small business evaluation factors.
