1. About Slip ring

JARCH Slip Rings are electromechanical devices for transmitting electrical power, control signals, and/or data from a stationary to a rotating structure (or vice versa). We offer a complete range of slip rings for transmitting voltage from mV to 36 kV and currents from mA to 3600 A. All the series are suitable to be mixed with signals and data. Customized solutions can go further reaching up to 13000 A and 43.2 kV. We always apply the best technology to meet your needs: double or multiple brushes, gold wires or bundle wire contacts. We can provide composition from a few poles to several hundreds, based on the requirements of your application. Slip Ring Assemblies can be supplied either as open, “non-enclosed” types for special customer adaptations, or totally enclosed with high impact plastic or metal housing, suitable even for hazardous locations. Additional rotating couplings are available for fluids or gases and fiber optic swivels can be integrated.

2. Product Overview:

Our JARCH industrial-grade slip rings are engineered to provide reliable transmission of power, signals, and data in rotating applications. Designed for durability and precision, they are widely used in wind turbines, robotics, cranes, packaging machines, and medical equipment. With low electrical noise, high-speed stability, and long service life, our slip rings ensure continuous 360C rotation without cable tangling.

1. Do all the published standard items have 2D drawings and 3D drawings?

Yes, sure. email us at kris@szjarch.cn for more information.

2. Which medium slip rings can be customized, and what parameters are required?

Through the medium: gas, liquid, electricity,Ethernet, optical fiber, gas-liquid-electric mixing and so on

3. For electrical slip rings, the parameters below are required:

a. Circuits number (ring numbers), current, voltage, rotating speed, temperature, protection grade;

b. Whether transmitting signal is required? What kinds of signal? Whether the signal should be shielded?

c. The inner diameter (ID), the required length, width, height. Any specific requirements for them? For example, the

maximum height should be under XXmm.

4. For pneumatic or hydraulic slip rings, the parameters below are required:

a. What kind of gas or liquid is it? Our slip rings can transmit pneumatic(vacuum, air, gas...), hydraulic (oil, water, cold liquid...), etc.

b. Pressure, rotating speed, the temperature of the medium being transmitted;

c. Port size: G1/8 or PT1/4, etc.;

d. The inner diameter (ID), the required length,width, height; Any specific requirements for them? For example, the maximum height should be under XXmm.
