UNSPSC 31163011: Jaw coupling

A type of coupling device that requires no lubrication and has no metal to metal contact.

UNSPSC 31163011 Jaw coupling, a Commodity code, shows limited direct activity in recent state and local procurement records. The code's nominal scope — mechanical power-transmission couplings that join rotating shafts — does not align with the recent opportunities tagged under this code. The City of Philadelphia's micro purchase for anchoring and buoy components (B2728124, due October 8, 2026) and silo accessories (B2727866, due September 2, 2026) fall outside jaw coupling's typical application in industrial machinery, pump systems, and equipment maintenance. Texas Health and Human Services Commission procurements in the same period—telecom parts and tools (HHS0017595 V2, due October 2, 2026), door hardware and locks (HHS0017874, due August 31, 2026), and maintenance supplies across multiple state facilities—similarly reflect miscellaneous building and facility operations rather than precision mechanical coupling systems. The Indiana Department of Public Works' traffic sign hardware solicitation (RFB14DPW1817, due October 15, 2026) addresses structural fasteners and bollards but not shaft couplings.

Recent issuers include municipal procurement offices (Philadelphia, Indianapolis, Austin), county governments (Hillsborough County, Florida), state health and human services agencies (Texas HHSC), and cooperative purchasing vehicles (Sourcewell on behalf of multiple Washington counties). However, these bodies are acquiring general maintenance supplies, equipment components, and operational consumables—not industrial transmission equipment. Geographic activity concentrates in Texas, Pennsylvania, Florida, Indiana, and Washington, but the match between code and actual procurement scope is weak. The code appears underutilized or mistagged in current state and local procurement systems. Firms pursuing jaw coupling opportunities should monitor industrial manufacturing, wastewater treatment, public works equipment maintenance, and transit authority mechanical-systems contracts rather than rely on this code's recent posting activity.
