UNSPSC 31163024: Flange type flexible coupling

A coupling that drills the diameter of the bolt hole of the main body of the flange slightly large to permit the deviation of the shaft center in a way of inserting the bush and convey the power by fixing the flange with the bolt.

UNSPSC 31163024 Flange type flexible coupling is a Commodity code that covers mechanical power transmission components used to connect rotating shafts in machinery and equipment. State and local governments purchase these couplings primarily as components within larger infrastructure, mechanical systems, and equipment maintenance projects rather than as standalone items. The issuing bodies soliciting work under this code span county governments and special-purpose authorities managing parks, utilities, and facilities.

The source records show limited recent activity directly aligned with the coupling scope. The single posted opportunity—DeKalb County's 2026-076-ITB for Reconstruction of the DeKalb Tennis Center in Decatur, Georgia, with bids due July 13, 2026—centers on IT and low voltage infrastructure installation for a recreation facility and does not reference flexible couplings or mechanical power transmission work. The code sees minimal documented state and local procurement activity in the recent opportunities block, suggesting either infrequent standalone solicitations for couplings or procurement bundled within broader equipment or construction packages that carry different UNSPSC codes.
