Industrial Slip Ring Assemblies for 360° Rotating Power & Signal
Stop wire twisting in rotating machines. JARCH builds complete, ready-to-use slip ring assemblies that combine electric power, Ethernet, signal, and air/oil lines into one smooth rotary unit.
What is a Slip Ring Assembly?
A slip ring assembly (also called a rotary electrical joint assembly) is a complete electromechanical device used to send electrical power, signals, data, or fluids from a stationary structure to a continuously rotating shaft without twisting cables.
Unlike a simple loose slip ring component, an assembly is a fully integrated, enclosed unit. It comes factory-assembled with internal conductive rings, gold-alloy brush blocks, precision bearings, sealing rings, mounting flanges, and pre-wired cables—making it ready for immediate drop-in installation on industrial machinery.
What is Inside a Complete Slip Ring Assembly?
A full slip ring assembly includes all parts pre-built and ready to install on your machine
Made of aluminum alloy or 304/316 stainless steel. It protects inner parts from water, dust, oil, and harsh weather (IP54 to IP68 rated).
We use gold-on-gold contact technology. This keeps electric noise very low and gives stable data transfer without losing signals.
High-precision bearings make sure the assembly turns smoothly at speeds from 0 to 1,000+ RPM with long working life.
Comes with color-coded lead wires, connectors, or terminal plugs so your technical workers can connect it quickly.
Combine Everything in One Rotating Assembly
Instead of installing different rotary parts, JARCH can put power, internet data, and air/hydraulic pipes together inside one small housing:

Frequently Asked Questions (FAQ)
Quick answers to common engineer and buyer questions
Q1: What is the difference between a slip ring and a slip ring assembly?
A slip ring usually refers to the internal conductive ring and brush parts alone. A slip ring assembly is a complete, fully housed unit that includes protective enclosures, precision bearings, sealing, mounting flanges, and pre-wired cables ready for fast installation.
Q2: Can I combine power, Ethernet, and pneumatic lines in one assembly?
Yes! JARCH specializes in hybrid slip ring assemblies. We can combine high-current power (up to 1000A), Gigabit Ethernet, optical fiber, and 1-12 channel air/hydraulic rotary joints inside a single compact housing.
Q3: How do I choose the correct IP rating for outdoor or marine use?
For indoor factory automation, IP54 or IP65 is sufficient. For outdoor cranes, cable reels, or marine equipment exposed to heavy rain and sea spray, we recommend our sealed IP67 or IP68 waterproof assemblies with stainless steel housings.
Q4: Can you provide 2D/3D CAD models before I place an order?
Yes. Our engineering department provides free custom 2D dimensional drawings and 3D STEP files within 24 hours so your engineering team can test fitting inside your CAD software.
Q5: What is the typical lead time for a custom slip ring assembly?
Standard models ship within 3-5 business days. Custom engineered assemblies with unique dimensions, high currents, or special connectors usually take 1.5 to 2 weeks for manufacturing and factory testing.
