UNSPSC 31171905: Chain wheel

A chain pulley, or sprocket wheel.

UNSPSC 31171905 Chain wheel is a Commodity code that sees narrow, specialized activity in state and local procurement focused on replacement and maintenance gearbox components for industrial and utility infrastructure. Recent solicitations show state and local agencies purchasing specific gearbox assemblies, taper bushed reducer units, and related drivetrain components for water reclamation facilities, fish screen operations, and facility reconstruction projects. The issuing bodies are primarily county governments and state natural resource agencies—Hillsborough County Board of County Commissioners, Oregon Department of Fish and Wildlife, and DeKalb County—soliciting through ITQ, intermediate procurement, and ITB notices for discrete equipment replacement and retrofit work rather than ongoing supply relationships.

Activity under this code is geographically dispersed across the Southeast and Pacific Northwest, with recent opportunities in Georgia, Florida, and Oregon. The Hillsborough County ITQ for two Dodge taper bushed reducer gearboxes and four taper bushing kits (ITQ2600239, due May 8, 2026, estimated at $30,400.00) and the Oregon Department of Fish and Wildlife RFQ for John Day Screen Shop gearbox components—Hub City left and right cradles and paddlewheel assemblies (S6350000017069, due June 11, 2026)—represent the primary recent activity. A third opportunity from DeKalb County (ITB 2026-076-ITB, due July 13, 2026) nominally tagged to this code in fact solicits IT and low-voltage infrastructure work for a tennis center reconstruction and shows no connection to chain wheel or gearbox procurement. The code demonstrates limited, project-specific demand with no evidence of standing cooperative purchasing agreements or blanket orders at this tier.
