UNSPSC 31171544: Plummer block bearing

A mounted bearing used to provide support for a rotating shaft with the mounting surface on a parallel line with the axis of the shaft.

UNSPSC 31171544 Plummer block bearing is a Commodity code representing pillow block and flange-mount bearings that state and local governments procure as replacement and maintenance components for rotating machinery across facilities and infrastructure. State and local procurement activity under this code shows no recent substantive contract opportunities; the single recent posting from Williamson County Purchasing Department in Texas is a notice of office relocation on July 14, 2026, which contains no procurement scope, deliverables, or contractual terms.

Without active solicitation records, the geographic spread and issuing-body concentration under this code cannot be characterized from current data. Plummer block bearings typically flow through state and local maintenance contracts for water systems, wastewater treatment, HVAC equipment, and industrial facility operations rather than as standalone commodity purchases, which may explain the limited recent standalone solicitation visibility in state and local notice systems.
