UNSPSC 31171525: Bearing liners

UNSPSC 31171525 Bearing liners is a Commodity code that in recent state and local solicitations covers large-diameter water treatment plant valves and their installation components, including motor-operated metal-seated ball valves, actuators, and associated removal and replacement work. The recent posting activity shows water utilities as the primary issuing bodies, with procurement spanning valve equipment, labor for removal and installation, crane services, commissioning support, and warranty terms. The scope reflects capital infrastructure maintenance at treatment facilities rather than bearing liners in a traditional mechanical sense; the code's nominal name does not align with the water-utility valve work actually being solicited under it in current state and local notices.

Recent activity concentrates in Texas. West Travis County Public Utility Agency (WTCPUA) issued an RFQ for Raw Water Intake Ball Valve #1 Purchase and Installation, posted August 13, 2026 with response due September 2, 2026, requiring purchase and installation of DeZURIK VBL AWWA metal-seated ball valves with AUMA modulating actuators at its Water Treatment Plant in Austin, Texas. San Bernardino County Project & Facilities Management issued ITB 6391 for Parts & Supplies in May 2026, covering over 500 line items including motors and pumps; response was due June 19, 2026. The code shows limited recent volume and geographic concentration in a narrow water-utility subsector; no other issuing bodies or states appear in the recent-opportunities block.
