UNSPSC 31163018: Bellows coupling

A type of flexible coupling designed to transmit torque while permitting some radial and axial and angular misalignment.

UNSPSC 31163018 Bellows coupling is a Commodity code that refers to flexible mechanical connectors used in rotating-shaft and vibration-isolation applications, yet the recent state and local procurement activity under this code shows minimal relevant sourcing. DeKalb County's June 2026 ITB for reconstruction of the DeKalb Tennis Center in Decatur, Georgia—posted under this code—centers on information technology and low-voltage infrastructure installation, including conduit, raceways, cabling, and terminations, rather than bellows couplings or mechanical power-transmission components. The mismatch suggests either a coding error in the county's procurement system or a narrow application of bellows couplings as an incidental component within the larger IT infrastructure scope.

The single recent opportunity identified under 31163018 does not reflect typical bellows coupling procurement. DeKalb County's ITB, with a response deadline of July 13, 2026, requires a contractor to furnish and install complete IT and low-voltage systems meeting DeKalb County Department of Innovation and Technology standards, coordinate device locations, and deliver testing and final documentation—a scope unrelated to mechanical couplings. The code shows little recent activity reflective of bellows coupling sourcing by state and local bodies, limiting visibility into current demand patterns or geographic concentration in this commodity class.
