UNSPSC 31171716: Herringbone gear

Type of gear with two opposing helices to transmit power and motion between parallel axes. The mirrored halves of the gear face have teeth that resemble an arrow head or the letter V.

UNSPSC 31171716 Herringbone gear, a Commodity code, shows minimal recent activity in state and local procurement, with only one directly relevant solicitation among recent opportunities. The Oregon Department of Fish and Wildlife issued an intermediate procurement on June 4, 2026, requesting gearbox assemblies (Hub City Gearbox cradles and paddlewheel components) for the John Day Screen Shop fish screen system, with quotes due June 11, 2026—a tight timeline reflecting urgent operational needs. The three other opportunities posted during the same period diverge significantly from herringbone gearing: the DeKalb County, Georgia ITB for tennis center reconstruction focuses on IT and low-voltage infrastructure rather than mechanical drive components; the Hillsborough County, Florida ITQ sought Dodge taper-bushed reducer gearboxes and taper bushings for water reclamation facility equipment; and the Orange County, Florida RFP for continuing engineering services for utilities projects does not involve gearbox procurement. Only the Oregon opportunity directly targets gearbox components, and even that solicitation specifies alternative equivalent models, indicating supplier flexibility on brand and design.

Geographic activity appears concentrated in the Pacific Northwest and Southeast, with Oregon showing the only direct herringbone or gearbox-specific demand among recent postings. The issuing bodies across all four opportunities represent diverse jurisdictions—a state wildlife agency, two county governments, and a county utilities department—but only one procurement directly engages gear transmission equipment. The code shows low signal for business development purposes at this moment; herringbone gearing does not appear to be a recurring procurement category across state and local jurisdictions in the current opportunity pipeline. Firms targeting this code should monitor Oregon Department of Fish and Wildlife solicitations, water reclamation and wastewater facility upgrades, and industrial equipment supply to municipal utilities, but should not expect sustained volume.
