UNSPSC 31171558: Linear and rotary motion roller

A cylindrical roller that has the hole in the central location in order to accommodate the pin or shaft to combine the push stick, inducement device, joint, rocker arm, rotation table or horizontal bar.

UNSPSC 31171558 Linear and rotary motion roller is a Commodity code that state and local governments use to procure mechanical roller components and assemblies for equipment, machinery, and industrial systems. The code encompasses products ranging from conveyor rollers and ball bearings to drive rollers and linear motion components used in manufacturing, facility operations, material handling, and equipment maintenance. The issuing bodies soliciting under this code span county purchasing departments, municipalities, and state agencies, though activity under this specific code appears limited in recent public notices.

The source provides no recent state and local contract opportunities with procurement scope, response dates, or issuing-body detail that would support a meaningful assessment of current market activity under this code. The single posted notice — from Williamson County Purchasing Department in Texas — is an administrative relocation announcement without contract opportunity information.
