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 is a Commodity code covering the procurement of self-aligning roller and ball bearings used in facility maintenance and industrial equipment repair operations. State and local governments source these components as line items within broader parts-and-supplies procurements that support building systems, mechanical equipment, and infrastructure maintenance. Purchasing departments, county facility management offices, and municipal maintenance operations issue these requests, typically bundled with other industrial supplies and components rather than as standalone bearing-specific solicitations. The work is driven by maintenance cycles at public facilities, utilities infrastructure, and equipment repair needs rather than new construction or large-scale manufacturing.

San Bernardino County Project & Facilities Management issued ITB 6391 on May 18, 2026 for parts and supplies to support facility maintenance and repair operations, with a June 19, 2026 response deadline; self-aligning bearings appear within the over-500-line-item catalog that bidders must price a minimum of 20 items from, with delivery required within 14 days of purchase order receipt and payment on Net 60 terms. The county applies a 5 percent local vendor preference for vendors with principal place of business within San Bernardino County boundaries. Beyond this California opportunity, the source documents no additional recent state or local solicitations under this code. Activity is sparse and episodic, concentrated in county-level facility management procurement rather than higher-volume state or municipal activity.
