Electrical slip ring and rotary unions – 360 degree continous rotation transmission of electric power, signals, data, gas, liquid


Slip rings – also known as rotary electrical contacts, electric rotary joints and collector rings – are devices that can transmit electric power, various types of signals and datas between a stationary part and a rotating part. As a manufacturer and thanks to our competent engineers, we at Ingiant know exactly what slip ring bodies must be able to do in your industry in order to guarantee technical functions, efficient automation and at the same time business success. But why do you actually need slip rings and rotary unions?

When the two parts of the machine rotate relatively 360 degrees without limit and continuous rotation, the wire needs to be connected to the rotating part, and the problem of wire winding will be encountered. At this time, a current connector (conductive slip ring) is needed to solve the cable winding caused by the 360 degree rotation ) to transmit power current and signal current. Slip rings are the only way to enable reliable, maintenance-free and low-wear power transmission, signal transmission and data transmission with simultaneous high system availability . Slip ring transmitters or rotary unions are also used for the wireless transmissionof liquid media (fluids) such as oil, water, grease and emulsion. The transmission of compressed air and gases can also be made possible by means of corresponding rotary unions.

Applications for Slip Ring Assemblies & Rotating Unions

Wide range of applications for slip rings

Slip rings are utilized in wind turbines to transfer electrical power generated by the rotating blades to the stationary components, such as the generator and control systems. 

Slip rings facilitate the transmission of power and signals to the rotating joints and sensors of robotic arms, allowing for unrestricted movement and precise control. 

In theater productions, slip rings enable the transmission of power and data to rotating platforms, lighting fixtures, and audio systems.

Furthermore, slip rings are employed in military and defense systems, such as radars, surveillance cameras, and communication antennas.

A: If you want to customize the special slip ring model, you need provide details as below:

1.operating speed(RPM)

2.the type of installation

3.installation size

4.channels(the No. of single wire besides cable)

5.rated voltage & current for power rings and signal rings

6.the signal type and related

parameters(very important)

7.operating temperature h.IP(sealing requirements)

A: It needs 7 to 15 days for standard products, 10 to 20 days for simple customized products,15 to 40 days for complex customized products.

A: Our delivery port is Jiujiang, China Mainland

A: Usually small orders can be delivered by air, big orders can be delivered by sea. It can be negotiated before delivering.

A:Robots are designed according to the requirements of the respective production situation. This often requires multi-axis systems that move the production material to the predefined positions. The Ingiant slip rings have been designed to transmit the power and data of the individual drives and to connect the sensors in all sections of the robot arm. Fast rotation speeds, maintenance-free design, high temperature resistance and extremely compact dimensions are the distinguishing features of our Ingiant slip rings.

A: Slip rings are generally found in most electromechanical machines and are a very versatile product. They are mainly used in crane technology, filling systems, packaging machines, medical technology and robots.

A: Slip rings play an important role in creating a continuous electrical connection between a static and a rotating system. Therefore, slip rings allow the transmission of power and data from static sources to a moving part.

A:The service life of the slip rings is individually adapted to customer applications. Ingiant basically offers three different qualities: 1. Quality S (Standard), 2. I (Industrial) and 3. P (Premium). Together with our customers, we determine the desired quality for our customers. In general, a service life of up to one billion revolutions is possible.

A:At Ingiant, in addition to the transmission of electrical energy, we offer solutions for the transmission of optical fibers, signals and fieldbuses such as 100 BaseT Ethernet in rotating systems. In addition to our data-transmitting slip rings, there are also slip ring solutions that enable the transmission of compressed air and gases through appropriate rotary unions.

A:Slip rings offer very reliable, maintenance-free and low-wear energy, signal and data transmission. This means that your Ingiant slip rings do not require maintenance.
