C-Cast™ Rotary Unions

C-Cast Rotary Unions
The C-Cast rotary union is available in both external and internal (journal-inserted) mounted options and single- and dual-flow configurations.

The internal-mounted, or journal inserted configuration, is the most popular and is found on the majority of continuous casting machines in North America and Europe. The C-Cast rotary union features a large bearing area, deep grease galleys, and two Quad-Seal O-rings that keep contaminants out of the sealing area. With a minimum of moving parts and low maintenance requirements, the C-Cast is preferred by steel makers and OEMs worldwide. The C-Cast union is rated up to 250°F (121°C), 150 psig (10 bar), and 100 rpm.
