Auto manufacturing is a diverse user of rotating unions for a broad range of parts or components and materials, whether machined steel, iron or aluminum, stampings, plastics, glass or paperboard. Rotating unions are used for operations that require coolant, lubricant or hydraulics.
Transfer Lines/Flexible Machining Centers
Complex metal components from engine blocks, to transmission housings require transfer lines for deep drilling facilitated by through-spindle coolant. Components from carburetors to gears, and valve stems require flexible machining centers.
Stamping/Forming Presses/Welding Machines
Large presses for auto stamp bodies or frames use air or hydraulic clutches with rotating unions. Welding equipment including robotic, TIG welders employ rotating unions for air clamping devices.
