UNSPSC 31171532: Self aligning bearing

Ball bearing having two rows of balls with a common sphered raceway in the outer ring.

UNSPSC 31171532 Self aligning bearing, a Commodity code, covers replacement and installation of specialized bearings and bearing-related components in industrial and municipal infrastructure applications. State and local governments procure self-aligning bearings primarily as part of larger facility maintenance, equipment repair, and infrastructure projects — including water treatment plant upgrades, HVAC system maintenance, and general facility support operations. The code spans both the procurement of bearing components themselves and associated installation, removal, and commissioning services where bearings are critical to equipment function.

Recent solicitation activity shows mixed issuing bodies across Texas and California. West Travis County Public Utility Agency issued an RFQ in August 2026 for raw water intake ball valve purchase and installation at its Water Treatment Plant in Austin, Texas, due September 2, 2026 — a project requiring removal of existing equipment, installation of motor-operated valves with actuators, and commissioning support. San Bernardino County Project & Facilities Management released an ITB in May 2026 for parts and supplies supporting facility maintenance across over 500 line items, including motors and pumps potentially incorporating bearing components, with a June 19, 2026 submission deadline and a local vendor preference of 5 percent for San Bernardino County–based businesses. Activity is geographically dispersed across Texas and California, with municipal utility agencies and county facilities departments as primary buyers. The code shows limited recent activity specifically tagged to self-aligning bearings as a discrete procurement line; most opportunities embed bearing procurement within broader equipment, valve, or parts-and-supplies solicitations.
