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.

Most common media used for cooling in a variety of applications including printing, plastics, tire and rubber, steel, and aluminum casting
Common media that expands the temperature range of water for both heating and cooling, primarily rolls
Media used for pneumatic applications that transmit air at specific pressures or volume, including clutch, brake, machine tool, holding, clamping
Media used for applications that deliver fluid pressure for actuation, clamping, and, indexing
Media used for hydraulic applications that deliver fluid pressure for actuation, clamping, indexing; brake fluid requires unique sealing technology vs. hydraulic
Most common media for machine tool applications; through-spindle coolant dispenses at the cutting surface for greater efficiency than flood cooling
Minimum quantity lubrication or MQL is a mixture of air and coolant prevalent in machine tool applications
Media used for heating of rolls for a variety of applications including plastics, paper, tire, and rubber
Media used in heating applications, primarily rolls for paper, corrugating, converting, tire and rubber, and food processing
