The fluid is sealed by precision, micro-lapped seals that provide a uniform, full-flow design. The union is supported by two widely-spaced anti-friction bearings and is available with a bearing isolation system for added bearing protection. The X union is capable of intermittent dry running and features a 100% pure-molded carbon graphite or silicon carbide seal and tungsten carbide counterseat. 3

14 Technical Data otary union sizing otary unions that are used for liquid flow are typically sized so that the pressure drop is less than 0,20 bar (3 psi) for open-loop systems and less than 0,40 bar (6 psi) for closed-loop systems. The pressure drop through a dual flow rotary union is higher than the pressure drop through a single flow union of the same size, because the internal flow area is lower. Use the appropriate chart below for your configuration. Note that the pressure drop shown for dual flow unions is for the supply passage. The total pressure drop (flow in and flow out) would be approximately 2x this value.

Type X rotary unions do not require additional filtration other than what is recommended for the fluid circulation system (typically micron). Guarantee Type X rotary unions are tested prior to shipment and are warranted against manufacturing defects for 12 months. adant ohnson s global sales and service network stands behind its products and provides support to more than 150 countries worldwide. 16

17 Threaded supply pipe threaded supply pipe is used for dual flow installations and is connected to the rotary union elbow using BPT threads. ee page 15 for the BPT take-up dimension. The size of the supply pipe determines the flow rate for a particular union size. The larger the pipe size, the higher the potential flow rate for a given size union. To avoid excessive stress at the pipe thread, the supply pipe length should not be longer than 4x the overall length of the rotary union. Fixed tube supply pipe The fixed tube supply pipe is made of stainless steel tubing and is silver-soldered into the elbow of the rotary union. The lighter weight and thinner wall sections allow for higher flow rates and higher rotational speeds compared to alternative supply pipe designs. To avoid excessive stress at the tube-elbow interface, the supply pipe length should not be longer than 6x the overall length of the rotary union. otating supply pipe rotating supply pipe can be produced from tubing or iron pipe. The end of the pipe that is inserted into the rotary union elbow is machined to a specific tolerance to provide the proper fit and performance. It is recommended that the rotating supply pipe be supported inside the roll when attempting to use a supply pipe longer than 4x the length of the union. straight thread rotor (for example, BP or UN) is used to ensure concentricity. onnectors adant ohnson rotary unions are attached to roll journals using threaded, flanged, or quick-release nipples.

18 Other otary Unions t adant ohnson, our world revolves around designing and manufacturing rotary joints and precision unions to meet our customers needs. Based on more than 75 years of innovation, we produce thousands of different rotary union configurations for a variety of process industries. Our full line of standard rotating unions is used in a wide variety of applications including steam, water, thermal oil, coolant, hydraulic oil, air, and other media. If you do not see what you need, our rapid design product development group is ready to provide a custom design based on your specific application needs. Type X for steam and thermal oil ( 3 4" to 3") The X rotary joint is designed for steam and thermal oil applications with a stationary supply pipe. Its two internal carbon-graphite bearings permit self-alignment and long operating life even on cylinders that are not concentric. The convex seal ring and optimized seal diameter provide extended seal life and reduced maintenance for the X joint. The X rotary joint line is available in sizes from 3 4" to 3" and can be used in single or dual flow applications. The joint is rated up to 343 (650 F), 20 bar (300 psig), and 550 P. Type EL for steam and thermal oil (2" to 12") The EL rotary joint is designed for use with steam and thermal oil service. The double-guide design provides internal support for the joint and maintains alignment even when the roll or cylinder is not concentric. The EL is available in sizes ranging from 2" to 12" and is rated up to 343 (650 F), 50 bar (725 psig), and 200 P. 18

19 Type G for coolant, water, air, and hydraulic oil The G rotary union is a high performance, high precision union for coolant, water, air, and hydraulic oil applications. Type G unions are generally applied to spindles, gun drills, milling, and other machinery. The G union is designed for smooth-running at speeds up to P and pressures up to 400 bar (5800 psig) in sizes ranging from 1 4" to 5 8". Type P for pneumatic, hydraulic, and water applications The P rotary union is a custom-designed multi-passage union for pneumatic, hydraulic, and water applications. The precision ball bearings are lubricated for life and housing materials include stainless steel, aluminum, steel, or brass. tandard passage sizes are 1 8", 1 4", 3 8", 1 2", 3 4", and 1" with other sizes available. P unions are available with up to 12 passages and rated up to 107 (225 F), 207 bar (3.000 psig), and 500 P. Type OT for water cooling The Over-The-haft (OT) rotary union is applied to various types of driven rolls that require cooling through the driven side of the roll. The OT is made of stainless steel and bronze components and features a Quad-eal o-ring design for reliable sealing performance. For high-speed applications, a mechanical seal design is available. The OT rotary union is rated up to 93 (200 F) and 10 bar (150 psig). 19
