SLIP RINGS & ROTARY UNIONS
“Optimize your industrial processes with our high-quality slip rings and rotary unions.”
What are rotary unions and slip rings?
Slip rings and rotary unions are devices that allow the transfer power, signals or fluids between a fixed part and a rotating part.
There are several types of rotary joints depending on what they transfer. The most common are electrical rotating unions, which pass current and electrical signals. Other popular types are pneumatic rotary joints, which transfer compressed air, and hydraulic rotary joints, which handle liquids such as oil, are also widely used in a variety of applications.
More specific cases require optical rotary joints, specifically designed to transmit fiber optic signals; mixed type joints, which combine several types of transmission. We have specific rotary joints for demanding applications, such as wind turbines and rotating pedestals for military applications. Both applications work in extreme environmental conditions and our designs improve the operating efficiency and durability of the systems.
