UNSPSC 23153146: Machinery transmission and accessories

A transmission is the transfer of energy from where it's generated to a place where it is used to perform work using simple machines, linkages and mechanical power transmission elements.

UNSPSC 23153146 Machinery transmission and accessories (Commodity) covers specialized transmission equipment and component parts purchased by state and local governments for infrastructure, facilities, and equipment applications. Recent solicitations show purchasing concentrated in water and wastewater systems, corrections facilities, and specialized industrial applications—reflecting the code's role in supporting mission-critical mechanical systems rather than general maintenance items.

State and local issuing bodies under this code include county governments (Gwinnett County, Georgia; Orange County, Florida; Collier County, Florida; Palm Beach County, Florida; Indian River County, Florida) and municipal water authorities, with no school districts or transit authorities appearing in recent postings. County purchasing departments dominate the activity, often procuring as part of larger capital projects or facilities upgrades. Representative recent opportunities include Collier County's single-source procurement for Vaughan centrifugal and chopper pumps for wastewater treatment (PUR17185, June 2026, three-year contract through September 2029), Collier County's single-source for an Alfa Laval lime sludge dewatering belt filter press system (PUR17185, April 2026, three-year contract), and a Palm Beach County pre-qualification for industrial machinery components including bearings, belts, couplings, gears, and sprockets on an as-needed basis (RPQ68023009CC15, ongoing with $208,500 estimated funding). Gwinnett County's freezer-replacement project (BL109-26, August 2026 response deadline) included evaporator and condensing units as part of a sealed-bid IFB, reflecting the code's application in specialized mechanical systems. Activity is geographically concentrated in Florida (five recent opportunities across Collier, Orange, Indian River, and Palm Beach counties) and Georgia (Gwinnett County), with occasional Texas activity. Single-source and pre-qualification procurements predominate, signaling limited competitive bidding under this code and supplier relationships tied to specialized equipment standards and OEM exclusivity. Pricing for named opportunities ranges from $208,500 (Palm Beach pre-qualified vendor estimated value) to $7 million-plus (Orange County corrections facility security and access-control work, though that project's mechanical-components portion is not isolated). Set-asides and local preferences appear in pre-qualification structures (Palm Beach's 5% local preference and S/M/WBE designations) but not in recent sealed-bid procurements for specialized transmission and pump systems.
