UNSPSC 31170000: Bearings and bushings and wheels and gears

UNSPSC 31170000 Bearings and bushings and wheels and gears is a Family code that in practice encompasses miscellaneous auto and shop supplies, fleet maintenance parts and repair services, and MRO (Maintenance, Repair, and Operations) inventory for state and local equipment. State and local governments procure under this code broadly: oils, lubricants, filters, fasteners, hoses, belts, cleaning agents, safety equipment, and general shop consumables for fleet and facilities maintenance. Recent solicitations show transit authorities, cities, and state departments sourcing supplies on blanket purchase-order contracts with firm-fixed or discounted pricing, typically awarded to multiple vendors per category to ensure capacity. The Orange County Transportation Authority (OCTA) in California has posted two iterations of miscellaneous auto and shop supplies procurements (IFB 250457 and the earlier IFB 250325, both budgeted at $500,000 over two years), reflecting the scale and repetition typical of this code. The City of Tucson is simultaneously procuring comprehensive MRO supplies across twenty-five product categories through RFP 240078, valued at approximately $4 million over three years with cooperative purchasing potential through OMNIA Partners. The State of Oregon Department of Administrative Services is establishing a statewide master price agreement for auto parts and installation services (RFP S-10700-00016861, response deadline September 24, 2026) serving state agencies and cooperative purchasing members across five regional ODOT designations.

Recent activity concentrates in California, Arizona, Oregon, Florida, and Connecticut. OCTA's repeat solicitations in Orange County, California dominate the code's visible pipeline; the City of Tucson, Arizona appears concurrently with machine shop services (IFB 270172, cylinder head and engine rebuilding, due October 19, 2026); and the State of Oregon's statewide master agreement spans nationwide coverage through cooperative purchasing eligibility. Transit authorities and municipal public works departments predominate as issuing bodies, followed by state departments establishing cooperative vehicles. The City of Milpitas, California (IFB 26-229) sought five-year blanket purchase orders across five MRO categories with local vendor preference and prevailing wage compliance (due July 23, 2026). The Borough of Naugatuck, Connecticut (Solicitation 36927) posted a one-year hardware, lumber, and maintenance supplies bid due May 28, 2026. Geographic concentration leans heavily toward the West Coast and Southwest, with secondary activity in Florida and the Northeast. Evaluation is predominantly cost-based; DBE, MBE, WBE, and local vendor preferences appear in many solicitations. Current contracting activity suggests healthy demand for established distributors capable of maintaining broad inventory, meeting delivery windows (typically four business days), and complying with prevailing wage, federal labor, and environmental standards.
