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.
