UNSPSC 31163021: Universal flexible coupling

A type of coupling where the angular or offset misalignment of the shaft reaches values which cannot be accommodated by flexible couplings.

UNSPSC 31163021 Universal flexible coupling is a Commodity code that typically covers rotating-shaft coupling products used in mechanical and industrial equipment. However, the recent state and local contracting activity tagged under this code shows little direct relevance to flexible couplings as traditionally defined. The single recent opportunity — DeKalb County's June 2026 ITB for reconstruction of the DeKalb Tennis Center — is primarily scoped around information technology and low-voltage infrastructure installation, including conduit, cabling, raceways, and termination work, with no mention of coupling hardware or rotating-equipment assembly. The mismatch suggests either a coding error in the source data or a narrow incidental component within a broader infrastructure project that does not reflect the primary commodity scope.

Absent additional recent opportunities properly tagged under this code, there is insufficient activity to characterize the issuing-body mix, geographic spread, or demand pattern for universal flexible couplings in state and local procurement right now. The sourced record does not support reliable conclusions about active buyers or regional concentration in this commodity category.
