UNSPSC 31171504: Ball bearings

UNSPSC 31171504 Ball bearings, a Commodity code, encompasses rotating components and fastening elements that state and local governments procure as replacement parts and maintenance supplies for facility operations, water treatment infrastructure, and mechanical systems. Recent solicitations show that the code captures both specialized industrial components — such as ball valves with bearing assemblies for high-pressure water systems — and commodity-grade fasteners and replacement parts bundled into broader maintenance supply contracts. Issuing bodies range from single-purpose utilities (water districts, county public utility agencies) to county facility-management departments and special-purpose districts. The work involves procurement of new replacement bearings and bearing-equipped assemblies, removal and disposal of worn components, and installation labor at customer sites; vendors frequently bundle procurement, delivery, installation coordination, and warranty terms into single RFQ or ITB responses.

Recent activity centers in Texas and California. West Travis County Public Utility Agency (WTCPUA) in Austin, Texas issued RFQ RFQRWIBALLVALVEPUMP120260902 on August 13, 2026 (due September 2, 2026) for the purchase and installation of four motor-operated metal-seated raw water ball valves — including bearing and seating assemblies — at its Water Treatment Plant, requiring vendor quotes on equipment, removal and disposal, labor, crane services, freight, and warranty terms. San Bernardino County Project & Facilities Management issued Formal Invitation to Bid 6391 on May 18, 2026 (due June 19, 2026) for over 500 line items of parts and supplies across multiple facility categories; the procurement explicitly includes motors, pumps, and mechanical components where bearings are secondary procurement elements. San Bernardino County offers a local vendor preference of 5 percent for vendors whose principal place of business is located within county boundaries. No federal set-asides are mentioned in recent opportunities under this code.
