Rotating Unions
Rotating Swivels - Rotary Swivels - Rotary Couplings - Rotary Joints - Rotary Unions
Rotating Unions (also known as rotary swivels, rotary couplings, rotary joints) are precision mechanical devices used to transfer fluid from a stationary source, such as a supply pipe, into a rotating piece of machinery. A typical rotating union features:
- Ball bearings to support the rotating component (attached to the machinery) against the stationary component (attached to the stationary supply source)
- Mechanical seal to seal the media passing through the rotating union
Mechanical seal face materials and secondary seals will vary depending upon the fluid properties & operating conditions of the application. Likewise, bearing type, design, material & construction will also vary with application.
Rotating Unions are used in numerous 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, Paper Machine Calender stacks, Paper Machine Dryer Cans, etc.
