• Deep groove ball bearings to support the rotating component (attached to the machinery) against the stationary component (attached to the stationary supply source)
• End face balanced mechanical seal to seal the media passing through

The bearing type, design, material and construction vary with application. Likewise, the seal also varies depending upon fluid properties & operating conditions of the application.

Rotating Unions are used in certain manufacturing processes to cool, heat or transfer fluid (pneumatic or hydraulic) power.

Rotating Union applications include Air Clutches, Gear Boxes, Machine Tool Spindles, Textile Equipment, Rubber & Plastic Manufacturing Machinery, Steel Continuous Casting Machines and Paper Machine Calender stacks. In 1989 Deublin product line was expanded to include Steam Joints and Siphon Systems for Paper Machine Dryer Cans.

Duff-Norton Rotary Union®rotating joints are designed to provide a rotating seal between a stationary fluid supply and a revolving roll or drum. These joints are available in a wide range of sizes, from 1/8 to six inch nominal pipe sizes, in single and dual flow designs. In most styles, optically flat seal faces and ball bearings reduce torque and friction drag. The quality construction and broad performance characteristics of Duff-Norton joints make them ideal for transmitting liquids and non-toxic industrial gases to and from a wide range of rotating machinery in most industrial applications: dryer drums, extruders, calendars, laminators, press rolls, embossers and similar applications. Years of service in tough field applications prove these joints give long service, have fewer production down periods and require less maintenance than other types of sealing mechanisms. Custom-engineered models are available by special order. Please consult your local Duff-Norton Rotary Union®distributor, your local Duff-Norton district sales manager or the factory for further information.

There are three basic types of Rotary Unions®:

P: Plain	S: Stationary Siphon	RS: Rotating Siphon
Single Flow	Dual Flow	Dual Flow

There are two mounting methods for Rotary Unions®: shaft mounted, which may utilize either a threaded or quick release connection, and flange mounted in which the housing is mounted directly to the drum and rotates while the shaft remains stationary.

Applications:

• Textiles
• Tank Farms
• Machining Centers
• Clutches and Brakes
• Automobile manufacturing
• Chemical
• Printing and Converting
• Paper
• Rubber and Plastics
• Food and Pharmaceuticals
• and Many More!

Float-A-Shaft is a universal right angle gearbox coupling. It consists of two 45° helical gears that mesh at right angles. Designed to turn power around any corner, Float-A-Shaft can be operated in either direction and can slide axially along the drive or driven shaft. A light weight aluminum housing encloses the gears (serving as a structure support and a lubricant reservoir which are keyed directly to the shafts. Field-proven for over 35 years, the Float-A-Shaft's unique floating design maintains perfect alignment and eliminates the use of dangerous chain sprocket drives. Float-A-Shafts are available in either a low torque journal bearing or a high torque sealed roller bearing series. Rated for a maximum of 500 RPM. Metric models are available.
