Around the shaft rotary union

Around The Shaft Rotary Unions - 5Series - Duff Norton. What is a rotary union? The shaft is the component that carries the medium through the rotary union into the drum or roll. In many cases the shaft will turn with the drum or roll. In some cases, like in larger flanged rotary unions , the shaft may be stationary while the housing rotates.

The bearings and seal are typically assembled around the shaft. Over-the-Shaft Rotary Unions Over-the-shaft (OTS) rotary unions are used with roll journals that contain internal passages and require fluid conveyance through the journal into the roll. An OTS rotary union seals around the journal and transfers fluid in and out of the passages as the journal rotates. Media transfers into the shaft from the mounted position of the rotating union.

The Series 6Rotherm Rotary Joint is designed for applications requiring one or two passages that transfer fluid into or out of a rotating shaft. Typical applications are for introducing fluids when the end of the shaft is not available for more traditional rotary joints. The Rotary Joint is designed to fit tightly on an existing shaft , locked into place with three set screws and sealed to the shaft with O-Rings.

Rotoflux around the Shaft Union for Water, Air, Vacuum, Hydraulic. Rotary Joints and Rotary Unions that can be configured for installation at the end of a shaft or around -the- shaft. Design Considerations for Rotating Unions Sealing Technology. Pass Threaded Shaft Rotary Unions. They all function the same way but have taken on different names over time and through translation around the world.

Rotary Systems offers a wide range of in-stock rotary unions from our standard product lines to match your media type, pressure, spee and temperature specifications. These unique rotary union designs offer diverse technologies such as mechanical seals, Teflon seals, and hydrostatic seals with single passage and multiple passage options. Rotary Unions (also: Rotary Joints, Rotating Unions ) are required for the transfer of media between stationary and rotating machine parts in almost all branches of industry. According to the numerous applications, different requirements are placed on a Rotary. See the products and contact us for any information.

On an offshore hose reel, rotary unions (integrated with electrical slip rings) transfer hydraulic flui data and power signals through the reel hose down to subsea equipment. DSTI rotary unions reliably seal and transfer fluid such as water, air, hydraulic oil, coolant, steam, and other media types from stationary sources to rotating parts. The RX rotary union uses a balanced seal with special ball bearing or optional tapered roller bearings to support the rotor. This rotary union from Kadant Johnson incorporates the latest.

DSTI rotary unions ( rotary joints) reliably seal and transfer fluid such as water, air, hydraulic oil, coolant, steam, and other media types from stationary sources to rotating parts. A rotary union is a union that allows for rotation of the united parts. Fluids typically used with rotary joints and rotating unions include various heat transfer.

The housing unit also includes the outlet port of the rotary union. These are usually the stationary components of the rotary union. Shaft : Shaft of a rotary union of water carries the medium in terms of course of the rotary union over the drum. The other two components of the rotary union are generally assembled in the region of the shaft. The seal prevents the medium (water, oil, air, etc) from leaking outside the Rotary Union while the Rotary Union is in operation.

Duff-Norton uses four basic types of mechanical seals in its Rotary Unions : 1) pusher-type end face mechanical seal, 2) non-pusher type end face mechanical seal, 3) lip seals and 4) o-ring seal. There are numerous designs and configurations for rotary unions — in fact, they’re often custom-designed for the application — but all rotary unions are made up of four basic parts: the housing, one or more bearings, the shaft , and one or more seals. Our multiple-passage rotary unions are a convenient solution when you need to pass more than one type of media to and from rotating equipment.

Available in standard or flange mount configurations, our entire line of multi-passage rotary.
