NIGP 10518: Bearing Assemblies (Including Hanger Bearings and Custom-Made Bearings)

NIGP 10518 Bearing Assemblies (Including Hanger Bearings And Custom-Made Bearings), an Item code, covers fabrication and supply of bearing assemblies, hanger bearings, and custom-engineered bearing components for municipal water and wastewater treatment infrastructure. State and local governments under this code purchase complete bearing assembly sets, including auger bearing hangers and related shafts, typically for water reclamation plants and utility operations. These components are usually constructed from corrosion-resistant and stainless steel, fabricated to custom specifications with welding meeting AWS standards, and warranted against defects for a minimum one year. Issuing bodies soliciting under this code include municipal purchasing departments and utility authorities responsible for water and wastewater treatment operations.

The City of Lubbock, Texas issued ITB 26-19467-MA in February 2026 to procure four complete sets of auger bearing hangers and shafts for its South East Water Reclamation Plant, with bids due February 24, 2026. The solicitation required corrosion-resistant steel and stainless steel fabrication, AWS D1.1 welding compliance, delivery FOB destination to the plant, and submission of three professional references, fabrication timeline, and material data sheets. Bidders were evaluated on purchase price, reputation, quality, past performance, and HUB program compliance, with local business preference available under Texas Local Government Code 271.9051 for bidders within Lubbock city limits if their bid was within five percent of the lowest price. Activity under this code remains limited in recent records; the Lubbock opportunity represents the primary documented state-local solicitation for bearing assembly fabrication in the current data set.
