UNSPSC 31163027: Roller chain coupling

A coupling that tightens the two lines of roller chain to fit at the end of both axes attached to the sprocket to deliver the driving force.

UNSPSC 31163027 Roller chain coupling is a Commodity code that nominally covers discrete mechanical fastening components, but the recent state and local opportunities indexed under it diverge sharply from that scope. The two most recent solicitations — West Basin Municipal Water District's on-call pump and motor repair services (RFPTH0143) and DeKalb County's IT and low-voltage infrastructure installation for the DeKalb Tennis Center reconstruction — involve no roller chain couplings as discrete procurements. The code shows little relevant recent activity tied to its stated commodity. This mismatch reflects a common state and local tagging inconsistency; opportunities involving pump stations, motors, and mechanical systems are sometimes indexed under component codes even when the actual procurement is for integrated services or system-level work rather than discrete parts.

The issuing bodies in the recent record span a special-purpose water district (West Basin in Los Angeles County, California) and a county government (DeKalb County, Georgia), representing geographically dispersed jurisdictions. The West Basin opportunity, due October 1, 2026, is structured as an on-call RFP with a $1,000,000 not-to-exceed amount over two years plus a potential one-year extension, and includes set-aside incentives for SBEs, LBEs, and VOBEs; this work involves pump and motor repair, rebuild, and replacement services at eight recycled water facilities. The DeKalb County opportunity, due July 13, 2026, is an ITB for construction-phase IT and low-voltage infrastructure at a recreational facility. Neither opportunity represents procurement of roller chain couplings as a product line, and the code does not surface meaningful commodity-specific activity in current state and local markets.
