UNSPSC 31171542: Tensioner bearing

A friction reducing device designed to work with an axle, which it supports, while enabling another attached item to spin, absorbing the tension between the two.

UNSPSC 31171542 Tensioner bearing is a Commodity code that designates individual mechanical components used in rotating equipment and drive systems within state and local facility maintenance and operations. State and local governments procure tensioner bearings as part of broader parts-and-supplies buys supporting HVAC systems, motors, pumps, and equipment found in county facilities, administrative buildings, and municipal infrastructure. The solicitations under this code come from county purchasing departments and project-management offices responsible for facility operations and maintenance at the jurisdiction level.

San Bernardino County Project & Facilities Management issued ITB 6391 on May 18, 2026, with a due date of June 19, 2026, for parts and supplies spanning over 500 line items across motors, pumps, HVAC components, and related mechanical parts in support of facility maintenance operations. The source shows limited recent activity directly tagged to this Commodity code; the primary recent opportunity reflects acquisition as part of a broad county facilities maintenance program rather than specialized procurement of tensioner bearings as a standalone item. No other state or local opportunities are documented in the current record.
