Industrial Rotary Unions

Moog's rotary unions are currently used around the world for the transfer of media between stationary and rotating machine parts in almost all branches of the industry to ensure reliable transmission of media as oil, water, grease, emulsion as well as (compressed) air, gas, or vacuum. A wide range of speeds and pressures are offered.

Our rotary unions are designed for a variety of industrial applications. They are fully integrated solutions and can be combined with our electrical slip rings and fiber optic rotary joints.

Moog offers standard solutions as well as customized solutions on request.
