3 ULIN KPS TH WORL ROTTIN Since 945, eublin has grown from a small garage shop to the world s largest manufacturer of rotating unions. Today, eublin s international headquarters is located in Waukegan, Illinois, with manufacturing facilities, sales offices and warehouses located in 7 countries on four continents. Our worldwide distribution network allows end users all over the world to specify eublin unions when purchasing equipment made in another country. We re manufacturers ourselves, so we understand the importance of fast response time to keep your manufacturing process rolling. Wherever you re located, eublin has a stocking distributor nearby to meet your requirements quickly. UNIQU RQUIRNTS N USTO UNIONS Rotating unions must accommodate a broad range of materials, viscosities, temperatures, pressures and speeds. That s why the eublin product line offers over 500 standard unions, over,000 separate models. ven this extensive line cannot meet all the specialized needs required by our customers. That s why we manufacture an evergrowing line of custom unions to meet individual manufacturers particular requirements. In many instances, we can adapt or convert an existing union and offer a cost-effective solution to meet your exact specifications or ULIN

4 ROTTIN UNION OR VRY PPLITION Rotating unions are used in many manufacturing processes to cool, heat or transfer fluid (pneumatic or hydraulic) power. Typical rotating unions feature deep groove ball bearings to support the rotating component against the stationary component, and balanced, precision-engineered mechanical seals to seal the media flow. eublin rotating unions vary for each application, depending on design, bearing type, construction and material required. In 989, the eublin product line was expanded to include steam joints and siphon systems for paper machine dryer cans. Here are just some of the industries that rely on eublin for their unique rotating union needs: LUINU UTOOTIV N KIN R WSH QUIPNT HIL/PTROHIL/RINRY ONSTRUTION QUIPNT ISTILLRIS/RWRIS R QUIPNT LOOR & WLL OVRINS OO PROSSIN HINRY LSS NUTURIN INSULTION LUNRY QUIPNT LUR & WOOWORKIN HIN TOOL RIN ININ PPR - ONVRTIN PLNTS - ORRUTIN - PULP & PPROR - ROOIN PTROLU PLSTIS PRINTIN - USINSS ORS - LXORPHI - W OST RUR STL TXTIL TIRS TRUKIN ULIN S state-of-the-art manufacturing facilities are strategically located worldwide, and feature the latest N technologies including multi-axis/multi-function, robotic interfaces, single point threading and cylindrical grinding. These advanced machining techniques and proprietary processes allow eublin to achieve the most precise tolerances in the industry, and ensure superior union performance and service life or

5 W TRT PRISION S N XT SIN PRISION rotating union must be capable of containing high pressures while rotating at very high speeds. Smooth, easy rotation can only be achieved by exactly mating the seal faces to minimize friction. Precision and tight tolerances are critical in the micro lapping of seal faces. ll eublin seals are micro lapped to an optical flatness within 2 light bands or " utilizing proprietary lapping machinery and compounds. This level of precision is essential for dependable leak-proof operation. Housings are machined on multi-axis twin-spindle lathes to obtain the necessary part-to-part precision. Rotors and other parts are turned on automatic bar machines to ensure true-running rotating unions without any wobble. This assures extended service life. XTN LI SLIN Responding to ever-increasing speeds and pressures, eublin pioneered xtended Life Sealing (.L.S.)..L.S. rotating unions offer outstanding performance under the toughest conditions, and can extend service life two to four times, depending on the severity of the application..l.s. unions use advanced materials such as tungsten carbide and silicon carbide to provide the best possible seal solution for the application. Where reliability is of prime importance,.l.s. should be specified to protect against contaminants and resist wear caused by rust, scale, chips and other harmful abrasives. PROSSIONL SRVI ROUN TH WORL t eublin, our service is as reliable as our products. iven the importance of rotating unions to your equipment s performance, our products have to be reliable. To provide you local and emergency service, we have a worldwide service network consisting of whollyowned subsidiaries and authorized distribution network. Whether you need a spare part, a new product, technical advice, or help with an ongoing design project, our experienced customer service representatives and engineers are always available to provide immediate assistance. LN HNIL SL The greater the pressure on a rotating seal face, the greater the friction, torque and wear on the union. That s why eublin rotating unions feature "balanced mechanical seals." With this technology, the thrust load or seal face contact pressure is kept to a minimum regardless of media pressure. This reduces wear, resulting in longer seal life. The spring-loaded seal is keyed so that it cannot rotate or creep, which can cause premature failure in secondary seals, resulting in a leaking union. or all your rotating union requirements no matter how unique or complex you can rely on eublin. NUR SYST ULIN ordering numbers for standard rotating unions consist of 2, or 4 number groups. ach group describes a particular characteristic feature such as application, seal combination or rotor connection (refer to ordering example). Rebuilding and repair kit numbers differ from their respective rotating union numbers by the insertion of a letter ( or ). The letter stands for a rebuilding kit, and the letter for a repair kit (refer to ordering example). Unbalanced echanical Seal ntire line pressure is applied to seal face. ULIN alanced echanical Seal Partial line pressure is applied to seal face. ORRIN XPL: rotor seal combination model / series / size Service kit Plus elbow for duoflow design Service kit or ULIN 5

10 eublin water service unions can be adapted for uoflow applications where a single media is circulated through and around the supply pipe. uoflow elbows are available in styles to accept a variety of different supply systems. The guidelines shown below should be carefully considered. poorly designed supply system can contribute to premature union failure. ustomer Shaft uoflow Supply Pipe Installations dapter* Pilot asket Where long pipes or high speeds are required, an adapter should be used to avoid transmitting stresses from heavy pipes, cascading water or vibrations to the union. typical adapter is illustrated. Union Stationary Tube lbow Rotating Pipe* Rotor *Supplied by customer. arbon illed T earing* asket* Outlet Inlet Threaded Pipe The largest threaded supply pipe achieves the maximum flow rates available for a particular size union. Stresses at the pipe thread can cause breakage allowing the pipe to fall into the roll. or this reason pipe lengths longer than 4 union lengths (4 x ) and rotational speeds above 000 RP should be avoided. ixed Tube Thin wall stainless steel tube silver soldered into the uoflow elbow produces the strongest, lightest weight assembly. The thinner wall sections allow greater flow rates than the threaded pipe. aximum flow rates are obtained with the largest tube available for a given size union. Tube length is usually limited to 6 union lengths (6 x ). Speeds to 500 RP are possible. Rotating Pipe Rotating pipes are fastened internally to rotate with the roll. The uoflow elbow helps to support the pipe and restrict crosstalk between passages. The pipe must be straight and concentric to the center line to avoid excessive loading of the union. The union must also have a rotor with a straight thread (xample "-4" UNS) rather than a tapered pipe thread to assure concentricity. Rotational speeds above 000 RP should be avoided or

The O-Ringed union body can be installed in the solid axle and air lines connected to the rotor head. eublin has developed a number of hubmounted unions specifically designed to accommodate the passage of air between a vehicle s stationary axles and its wheels. This allows tire pressure to be varied from inside the vehicle s cab, and is already very popular in the logging industry and on military vehicles. The ability to vary the air pressure allows the driver to adjust pressure for the surface being traveled. Lower pressure with a broader footprint is suitable for soft terrain. Higher pressures and a smaller footprint is suitable for higher speed highway travel. odel /2" capacity, maximum pressure50 psi. max temperature 250, maximum speed,500 RP.
