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. Drilling rigs oil or gas use air clutches and brakes that require rotary unions. 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.

The bearings are always used to allow a part of the joint, either the shaft or the housing, to rotate. Fluids typically used with rotary joints and rotating unions include various heat transfer media and fluid power media such as steamwaterthermal oilhydraulic fluidand coolants. Rotary unions are also heavily used in crude oil processing, the chemical uion, commercial food production, and pharmaceutical applications.
While rotary unions come in many shapes, sizes, and configurations, they always have the same four basic components: The textile industry is a large user of water, steam and hot oil unions.
There are two kinds of car wash facilities that use unions: Converters use rotary unions for heating and cooling rolls, as well as winders with air clutches and brakes. Rubber is compounded on big industrial mixers which use rotary unions for water cooled rolls. Thank you for subscribing. These mechanical gadgets are used to move liquid from a stationary Web offset and sheet printing equipment use many rotary unions on the ink vibrator and chill rolls.

The steel industry is one of the largest users of rotary unions primarily for continuous casting rotzry CCM which use rotary 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. It has radial housing connection and an independent rotating union. A multiple port rotary union looks like a perforated cylinder. A rotary union with a straight port transfers the substance directly through the rotary union.
With DirectIndustry you can: The second most important part of the rotary union is the bearing. Views Read Edit View history. In larger rotary unions the housing is usually bolted to the drum or roll using unino flange. This stainless steel rotor is housed in forged brass and comes with 3 vent holes.
With DirectIndustry you can: At the end of the cylinder is a threaded screw with a seal or seals that lock on to it. Paper applications span the supply chain from the raw pulp and paper mills, to the downstream paper converters. In these cases the housing rotates at the same speed as the drum. Water unions are used to flush mud from the drill tip, and must withstand shock and vibration in this severe application.
