UNSPSC 31163013: Shaft coupling

A device for providing a connection, readily broken and restored, between two adjacent rotating shafts.

UNSPSC 31163013 Shaft coupling is a Commodity code with minimal recent activity in state and local procurement. The code nominally describes mechanical power-transmission components, yet the two most recent opportunities posted under it diverge sharply from that scope: one solicits electric motor and pump repair, rebuild, and replacement services; the other solicits IT and low-voltage infrastructure installation for a tennis center reconstruction. Neither opportunity involves purchasing or specifying shaft couplings as a product line. State and local procurement offices appear to apply this code inconsistently or as a catch-all for mechanical and infrastructure work that falls outside narrower classifications. The mismatch between the code's stated commodity and the actual work being solicited suggests limited utility for vendors specializing in shaft coupling supply or services.

West Basin Municipal Water District (Los Angeles County, California) posted RFP RFPTH0143 on October 5, 2026, for on-call pump and motor repairs, rebuilds, and replacement services across eight recycled water and pumping facilities, with proposals due October 1, 2026—a date that had already passed at posting and signals a possible administrative error or amended deadline. DeKalb County (Georgia) posted ITB 2026-076-ITB in June 2026 for DeKalb Tennis Center reconstruction including IT and low-voltage infrastructure, with bids due July 13, 2026. The geographic spread covers California and Georgia, with no clear pattern of repeat activity. Absent a substantive flow of opportunities directly aligned with shaft coupling procurement, this code does not represent an active market segment for business development focus under state and local procurement.
