Agriculture

Equipment used in grain harvesting including combines, tractors, grain carts and threshers, employ rotating unions. Once harvested, many crops will be processed with equipment that uses rotating unions. Food processing equipment that use rotating unions include cooling conveyors, flaking mills, shredders, steam cookers, starch dryers, rotary cutters and roll-forming.

Car Wash

Car Wash

There are two kinds of car wash facilities that use unions: the automatic and the hand operated. Most manufacturers of automatic systems have several revolving brushes which use 55 series to introduce low pressure detergent water through the supporting shaft to the brushes. In addition touchless car washes have spinner s that require rotating unions to transmit high-pressure water into the spinning mechanisms. Model 22 union has been specifically designed for this type of application.

Converting

Converting

Downstream processing of paper, plastic film, foil and related substrate materials into finished, printed packaging such as bags, pouches, labels, tags, folding cartons and corrugated shipping cases is called converting. Deublin rotating unions are used in all types of converting for water, steam, thermal oil, air or hydraulics.

Machine Tool

Machine Tool

Nearly all modern machine tools and machining centers are equipped with so-called “flood coolant”. High-speed cutting tools require both cooling and lubrication to reduce the rate of tool wear and to prevent over heating which degrades the tool’s strength. For many machining operations, such as milling or hole drilling, flood-coolant systems are less effective at delivering coolant fluid to the cutting edge. In machining centers with through-spindle coolant (TSC), coolant fluid is conducted directly through the cutting tool to cool the cutting edge, reduce friction and remove chips. Coolant flows axially through a rotating union into the spindle and toolholder directly to the heat surface. Compared to flood-coolant systems, TSC pays for itself in terms of lower operating costs for tools and coolant. Deublin offers the greatest variety of seal technologies and mounting configurations to fit every machining application requirement. Rotating Unions may be used to transmit coolant, cutting oil, MQL, pressurized air in a bearingless or bearing supported configuration. Deublin seal technologies include Pop-Off, Multi-media, AutoSense and a variety of other advanced technologies for all applications. Besides coolant delivery, Deublin unions are used for chucking, tool sensing, rotary index table and other machine tool applications. The selections in the website represent a small range of standard products. For critical applications, please contact Deublin.

Oil & Gas

Oil & Gas

Drilling rigs (oil or gas) use air clutches and brakes that require Deublin rotating unions. Deublin water unions are used to flush mud from the drill tip, and must withstand shock and vibration in this severe application. Oil and petrochemical refineries use batch mixers, flaking mills, blenders and drying rolls that each require Deublin rotating unions.

Paper

Paper

Deublin paper applications span the supply chain from the raw pulp and paper mills, to the downstream paper converters. Mills use steam joint and siphon systems and water unions for heating and cooling. Converters use rotating unions for heating and cooling rolls, as well as winders with air clutches and brakes.

Plastics

Plastics

The manufacturing of plastic materials encompasses a wide variety of applications including cast film, blown film, foam, flexible and rigid sheet extrusion, single and multi-layer co-extrusion, blow molding, thermoforming, pelletizing, wire and cable, injection molding and winding. Deublin rotating unions for water and thermal oil service are used for heating or cooling the many processing rolls throughout the wide variety of applications. In addition, Deublin rotating unions for air and hydraulic service are used in winding and injection molding applications. Many of todays modern winding applications will also utilize Deublin electrical slip rings.

Rubber

Rubber

Rubber is compounded on big mixing machines called Banburys which use Deublin rotating unions for water cooled rolls. Rubber extrusion is similar to plastic extrusion, with Deublin rotating unions used to cool the extruder screw. Tuber dies and calendars require similar cooling. Rubber tire manufacturing has it’s own Industry page.

Steel

Steel

The steel industry is one of the largest users of rotating unions primarily for continuous casting machines (CCM) which use Deublin rotating unions to cool the numerous rolls that support molten slabs as it moves by gravity through various segments onto a run-out table to downstream annealing and heat treating. The slab is formed into coil or sheet. Coil is further converted in processing centers that require hydraulic unions for actuation of mandrels.
