A rotary union (also known as rotary swivel, rotary coupling, rotary joint) is a mechanism used to transfer liquids and/or gases while rotating / swiveling from one connection to another. Rotary unions are engineered to endure a large range of temperature and pressure for a variety of conditions and environments. In addition, rotary unions may integrate multiple passages and handle different types of media concurrently.
Single passage rotary unions, double passage rotary unions and multiple passage unions are available in numerous material, seal and passage size options.
With fast developing of new technology and increased demanding of multifunctional equipments, fluid, gas, power, signal and data are required to deliver in one compact assembly. AOOD are able to incorporate an electrical slip ring to a rotary union in limited space to realize the complete control of one system. That is AOOD slip ring union, also called electrical-hydraulic rotary joint or electrical-hydraulic rotary union.
