Rotary Unions, Slip Rings and Combinations
Your benefits
Very high production rates
To meet the demands imposed by increased production rates in steel rolling mills, GAT has developed a rotary union that reliably supplies the coiler with hydraulic oil at high speeds. Minimal friction and wear ensure a very long service life.
High level of reliability
Rotary unions of the ROTOSTAT N and ROTOSTAT E series are renowned for their extraordinary reliability and unique emergency running properties. The hydrostatically controlled radial gap sealing system is designed for maximum durability with minimal leakage. Costly downtimes are prevented.
Complete system from a single source
If different media such as water and grease must be provided, several rotary unions can be combined to ensure reliable transmission.
- Coilers in cold and hot rolling lines
- Continuous casting machines / Slab casters
- Ladle turrets
- Other
