Capsulated Slip Rings
Slip Rings and Rotary Joints for 360° Continuous Power Signal and Data Transfer
INGIANT builds the rotating connection that lets your machine turn without winding a cable — power, Ethernet, fibre, HD-SDI, RF, air and liquid across one axis, from a 728 model catalogue or designed around your drawing.

What We Make
Thirteen Families of Rotating Connection One Engineering Problem
Every product on this site answers the same question: how do you get power, data or fluid onto a part that never stops turning? The format changes with the machine — a hollow bore for a shaft, a sealed capsule for a camera head, a separate rotor for a four metre turntable — but the job is the same.

What Problem We Solve
Four Failures That Start at the Rotating Joint
Cable wind-up
A harness that follows a rotating part fails at the flex point, and it fails in production rather than on the test bench. The slip ring removes the flex entirely.
Rotation limits
A ±180° limit forces an unwind move into every cycle. Continuous rotation removes that move and the cycle time that goes with it.
Contact noise
Signal drift and dropped packets usually trace back to resistance variation in the rotating contact. Precious metal pairs hold dynamic resistance variation under 10 mΩ.
Stacked joints
Three rotary joints on one shaft means three sets of tolerances. A hybrid body puts power, data, fibre and fluid on one axis with one mounting interface.
Why INGIANT
A Factory That Designs the Part Not Just Builds It
INGIANT designs and manufactures slip rings and rotary joints that carry power, signals, data, fibre, RF, air and liquid across a continuously rotating interface — so machine builders can turn a joint through 360° without winding or breaking a cable.

FAQ
Slip Ring Questions Buyers Ask First
What is a slip ring and when do I need one?
A slip ring transmits electric power, signals and data between a stationary part and a rotating part. You need one when two parts of a machine rotate through 360° without limit and a cable would otherwise wind up and break.
What technical data do you need to quote a custom slip ring?
Operating speed in rpm, the type of installation, the installation size, the number of circuits counted as single wires beside the cable, rated voltage and current for the power and signal rings, the signal type and its parameters, the operating temperature and the IP requirement.
How long is your production lead time?
7–15 days for standard products, 10–20 days for simple customised products and 15–40 days for complex customised products.
What can be transmitted through a slip ring?
Electrical power and low frequency signals, Gigabit Ethernet, USB, HD-SDI video, optical fibre, RF coaxial signals, and — through the matching rotary unions — compressed air, gas, water, oil and emulsion.
What service life do slip rings have?
Service life is matched to the application through three quality grades — S Standard, I Industrial and P Premium. In general a service life of up to one billion revolutions is possible.
What is your delivery port and how do you ship?
The delivery port is Jiujiang, China Mainland. Small orders are usually delivered by air and large orders by sea, negotiated before despatch.
Send Us the Axis and We Will Send You the Drawing
Rotating speed, installation size, circuit count, voltage and current, signal types, temperature and IP grade. That is everything we need to come back with a design.
