31--BEARING,SLEEVE
DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA AVIATION.DLA AV RICHMOND.DLA AVIATION · Response deadline: Tue, 20 Oct 2026
What the government is buying
The Defense Logistics Agency (DLA) Aviation is procuring bearing sleeves—a common aircraft component used to reduce friction between moving parts, support rotating shafts, and prevent wear in mechanical assemblies. These parts fall under Federal Supply Classification (FSC) 31, which covers bearings. Bearing sleeves are typically cylindrical liners installed in housings or bores to provide a replaceable wear surface, extending the service life of more expensive structural components.
DLA Aviation serves as the primary supply chain manager for military aircraft parts, supporting all branches of the U.S. armed forces. This procurement likely supports ongoing sustainment efforts for military aviation platforms, where bearing sleeves see routine replacement due to operational wear.

Who can bid
This opportunity is open to all responsible sources—no small business set-aside applies. Both small and large businesses may compete, including manufacturers of plain bearings and bearing sleeves and distributors who can meet DLA's technical and quality requirements.
Your firm should register in the System for Award Management (SAM.gov) and hold any required certifications for defense supply. Given NAICS 332991 (Ball and Roller Bearing Manufacturing), relevant experience in precision machining, metallurgy, or aerospace parts fabrication strengthens eligibility. DLA suppliers typically must meet quality standards such as ISO 9001 or AS9100 and demonstrate traceability, material certifications, and counterfeit parts prevention protocols.
How to put together a competitive bid
Compete on total evaluated price, not just unit cost. DLA's automated procurement system evaluates offers based on total price after adjusting for transportation and other factors. Review the solicitation for exact evaluation criteria.
Verify your part numbering and technical data. The solicitation likely contains a National Stock Number (NSN), drawing requirements, or a manufacturer part number for the bearing sleeve. Ensure your product matches all physical dimensions, material specifications, and performance requirements exactly. Substitutions generally require prior approval.
Confirm your supply chain readiness. DLA Aviation often requires delivery within specified timeframes. Assess raw material availability and production capacity before committing to a delivery schedule.
Submit your quote electronically through DLA's internet bid board system. The notice is a Combined Synopsis/Solicitation, meaning the solicitation document is integrated with the synopsis and no separate RFP follow-up is anticipated.
Address packaging, marking, and documentation requirements. Military shipments require specific labeling under MIL-STD-129 and may need DFARS clauses for defense acquisitions. Small technical deficiencies in packaging or paperwork can render a bid non-compliant.
Review past procurement history. Search SAM.gov or DLA's procurement data for recent awards of similar bearing sleeves to benchmark pricing, though actual quantities and prior awardees vary by specific NSN and requirement date.
