The 600D Series Rotary Union is specifically engineered for clamping and unclamping applications in steel strip down coilers. Designed for high-speed and high-pressure operation, it delivers reliable hydraulic performance, superior sealing, and long service life in demanding steel processing environments.
The 600D Series Rotary Union is specifically engineered for clamping and unclamping applications in steel strip down coilers. Designed for high-speed and high-pressure operation, it delivers reliable hydraulic performance, superior sealing, and long service life in demanding steel processing environments.
The 600D Series combines two independently separated flow paths with a sealing and bearing arrangement built for the repeated clamp and unclamp cycles of a down coiler.
Individual flow paths provide reliable separation and transfer of multiple media.
Self-supported sealing design provides reliable sealing performance during operation.
Dynamic elastomeric sealing provides effective sealing for continuous rotary operation.
Hardened sealing rotor provides improved wear resistance and longer service life.
Widely spaced ball bearings help absorb side loads and provide stable operation.
A down coiler's clamping mechanism cycles continuously as strip is coiled and released — the union's sealing and bearing arrangement is built to sustain that cycling without degrading.
Individual flow paths provide reliable separation and transfer of multiple media, keeping the clamp and unclamp hydraulic circuits fully isolated from each other.
Self-supported sealing design provides reliable sealing performance during operation, with dynamic elastomeric sealing and a hardened sealing rotor sustaining sealing performance across repeated high-pressure clamp cycles.
Widely spaced ball bearings help absorb side loads and provide stable operation, keeping the union aligned and sealed under the mechanical loads typical of coiler duty.
