UNSPSC 31171715: Cylindrical gear

A disk or wheel, having cut teeth of such form, size, and spacing that they mesh with teeth in another part to transmit or receive force and motion.

UNSPSC 31171715 Cylindrical gear, a Commodity code, shows minimal alignment between the code's nominal scope and recent state and local solicitation activity. The code nominally describes cylindrical gears as discrete mechanical components, but recent opportunities tagged under it do not reflect that definition. Texas A&M University System posted an ITB (due October 28, 2026) for stainless steel diaphragm plates, which are fluid-system components rather than power-transmission gearing. Harris County has posted multiple ITBs in recent months for sign posts and mounting hardware, screw fasteners, communications infrastructure maintenance, HVAC services, landfill operations, door lock replacement, waste management, thermoplastic road-marking equipment, and election-accessibility ramps — none of which involve cylindrical gears or gearing systems. Monroe County (Florida) posted an RFS for door replacement at a sheriff's office facility. The pattern suggests that either the code has been applied incorrectly to unrelated industrial and operational procurement, or the code is not actively used by state and local buyers for its intended commodity.

The geographic activity centers on Texas, particularly Harris County (Houston area), which represents the overwhelming majority of recent postings, along with scattered activity in Florida (Monroe County) and the Texas A&M System. No evidence of sustained or recurring procurement under this code for cylindrical gears or related gearing products appears in the recent opportunities block. Prospective vendors should verify with issuing procurement offices whether opportunities truly require cylindrical-gear components before pursuing; the current record suggests the code is either underutilized for its intended scope or systematically misapplied to unrelated categories.
