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. Rotating Unions are used in numerous manufacturing processes to cool, heat, or transfer fluid (pneumatic or hydraulic) power.
Rotary Unions allow the feed through of water, glycol, air, hydraulic, coolant, MQL, hot oil, steam, vacuum and a variety of other media. Rotary Unions (Joints) can be configured for installation at the end of a shaft or around-the-shaft.
