Description

MULTI-PASSAGE ROTARY UNIONS Multi-passage (MP) rotary unions are used when more than one media are used simultaneously. An MP rotary union provides multiple seals between stationary connections and rotating equipment, such as a drum, index table, clutch, or spindle. The multiple independent passages permit the flow of the same or different media into or out of the rotating equipment. Power and fluid transfer media typically used with multi-passage rotary unions include hydraulic fluids, cutting fluids, air, or inert gas. Other media include steam, water, thermal oil, and coolant. When electrical power, signal, or data transfer is combined with fluid transfer, MP rotary unions include a through bore to accommodate a slip ring or are integrated directly with slip rings. STANDARD MP UNIONS Standard MP rotary unions are available in 2-, 4-, 6-, and 8-passage configurations and are suitable for vacuum and bidirectional pressures. MP rotary unions can be designed with up to 36 passages. Media types typically include oil, air, water, and coolant. CUSTOM MP UNIONS Have an application that requires a custom-engineered solution? Kadant Johnson’s rapid response product innovation team focuses on making the best solution possible. We work closely with you to develop reliable, efficient, and technically advanced products that meet your fit, form, and function criteria. 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 rotating journal and transfers fluid into and out of the passages.
