UNSPSC 31171535: Cartridge bearing

Bearing having the same properties as radial ball bearings except a wider width.

UNSPSC 31171535 Cartridge bearing is a Commodity code that covers individual bearing units and component parts for industrial rotating equipment. State and local governments procure cartridge bearings primarily as components within broader facility maintenance, water treatment, and equipment-repair operations rather than as standalone line items. Recent solicitations show these bearings being sourced as part of mixed-commodity acquisitions supporting water infrastructure, HVAC systems, pumps, and motors. The issuing bodies active under this code include county utility agencies, county facilities management departments, and regional water authorities. The work encompasses both direct purchase of bearing cartridges and, more commonly, procurement of bearing-containing assemblies or parts-and-supplies contracts that bundle bearings with related mechanical components.

West Travis County Public Utility Agency (WTCPUA) in Texas and San Bernardino County Project & Facilities Management in California represent recent activity, though the WTCPUA solicitation (RFQ RFQRWIBALLVALVEPUMP120260902, due September 2, 2026) focused on ball valves and actuators rather than cartridge bearings specifically, and the San Bernardino County ITB 6391 (due June 19, 2026) included motors and pumps among its 500-line-item parts catalog without itemizing cartridge bearings as a distinct line. No solicitations in the available block explicitly isolate cartridge bearing procurement as the primary scope. Recent activity appears concentrated in Texas and California, reflecting water utility and county facilities operations in those regions, though the source provides insufficient detail to establish whether cartridge bearings represent material volume or pricing under these opportunities.
