Features and Benefits

FEATURES and BENEFITS

9000 Series General Purpose Rotary Union

Advanced Sealing System

The Bellows Sealing System provides superior sealing performance throughout the wear life of the Rotary Union.

Superior Alignment

Dual bearings available in all sizes over 1-1/4 inch to provide superior alignment.

Resists Debris Build-Up

Compared to seals utilizing springs, the 9000 series bellows sealing system is more resistant to debris in contaminated media, which reduces clogging.

Easy Mounting

The flange attaches directly to the machine journal, providing inherently concentric mounting, minimizing overhang, and partially relieving bearing load to increase service life.
