UNSPSC 31171700: Gears

UNSPSC 31171700 Gears, a Class code, covers specialized mechanical transmission and drivetrain components that state and local governments procure for water treatment, sports facilities, environmental monitoring, and industrial plant operations. Recent solicitations under this code show state and local agencies buying concrete gear assemblies and related transmission equipment: polymeric chains for water infrastructure, gearbox units and sprockets for fish screen operations, and heavy-duty speed reducers and taper bushings for water reclamation facilities. The issuing-body mix spans county water utilities, state environmental agencies, county purchasing divisions, and city engineering departments, with repeat activity from the Oregon Department of Fish and Wildlife and Hillsborough County water operations.

Georgia, Florida, and Oregon dominate recent activity. Representative solicitations include the Oregon Department of Fish and Wildlife's June 2026 ITQ for John Day Screen Shop gearbox assemblies (Hub City gearboxes and paddlewheel components, four units each, delivery by August 13, 2026) and the Hillsborough County Board of County Commissioners' April 2026 ITQ for two Dodge taper-bushed speed reducers and four taper bushing kits (estimated project value $30,400, delivery to the Northwest Water Reclamation Facility, bids due May 8, 2026). Gwinnett County, Georgia, issued an IWQ in July 2026 for 150 units of polymeric chain (REXNORD NH78 or equivalent), due August 5, 2026, for delivery to its Department of Water Resources Central Facility. These are typically low-dollar, single-purchase orders placed through informal quotation, invitation to quote, or intermediate procurement processes with short bid windows and exact-specification requirements driven by compatibility with existing equipment.
